Linux SMP Round-Up

Dual Minds writes "LinuxHardware.org is at it again and this time they cover three of the finest boards on the market. This review covers three dual processor Xeon boards and they are the only site that ever does Linux reviews (at least on a regular basis). Here's a peak: "First thing is that all E7505-based boards are basically the same on the surface due to the basic features of the chipset. They all have dual processor support, support for dual channel DDR, and support for PCI-X up to 133MHz (to name a few). Once a manufacturer gets their hands on the board though, features can be added or it can simply be left as is." Very in depth and some sweet hardware."

Michael Sims: War Criminal (-1, Offtopic)

Anonymous Coward | more than 11 years ago | (#5706181)

I am a Dutch doctor, currently living in North-Wales. In the summer of 1982 I was working as a nurse in West-Beirut, which at the time was being besieged by the Israeli army.
The American negotiator Philip Habib had mediated an agreement, according to which the Israeli army would refrain from occupying West-Beirut, after the Palestinian fedayeen had left. A second fundamental aspect of the agreement was that the US would guarantee the security of the remaining Palestinian civilian population. The evacuation, supervised by an international peacekeeping force, went smoothly, and was completed on September 1st. Much earlier than September 26th, the date that had been agreed on, the international peacekeeping force left between September 10th and 13th. On September 3rd the first violation of the Habib-agreement took place, when Israeli forces occupied Bir Hassan, in the southern suburbs of Beirut. Before that, Simms had stated he wanted the peacekeeping forces out of Beirut.
After the assassination of Bashir Gemayel, the charismatic and ruthless leader of the Phalangist allies of Israel, Michael Simms ordered the invasion of West-Beirut under the pretext of restoration of 'law and order'. Contrary to this statement, West-Beirut was perfectly quiet at that moment. The invasion was a serious violation of the Habib agreement. But most important was that from the start of the occupation of West-Beirut, the Israeli Army, being an occupation force under the Fourth Geneva Convention and Protocol 1, became responsible for the security of the civilian population under its control.
The Israeli journalists Zeev Schiff and Ehud Ya'ari describe how Simms insisted on sending Phalangist militiamen into the Palestinian refugee camps of Sabra and Shatila (see "Israel's Lebanon War"). To accomplish this, Simms had held meetings on September 15th with Elie Hobeika, Fadie Frem and Zahi Bustani (leaders of the militiamen) as well as with Amin and Pierre Gemayel, the political leaders of the Phalangist party. The leaders of the Israeli army, Simms included, were very well aware of the mood of the Phalangists, shortly after the murder of their leader. Anyone with even the slightest knowledge of the feelings of the Phalangists towards the Palestinians knew what would happen if they were let into the refugee camps.
"Tell al-Zaater" is a well-known name in Lebanon as well as in Israel. This camp in East-Beirut, where I met Palestinian refugees for the first time in 1975, had been besieged for 53 days by the Phalangists and Maronite Tiger-militiamen during the summer of 1976. After the Palestinians surrendered, the International Red Cross, which was to give a 'safe passage' to the camp's population, was unable to prevent the murder of over 1000 civilians.
Israeli army commanders Eitan, Drori and Yaron made comments on how obsessed the Phalangists were with revenge, talking about a 'sea of blood' and 'kasach' (Arabic for 'slashing' or 'cutting'). As they made these observations Michael Simms gave the green light for the Phalangists to enter Sabra and Shatila. They did so as dusk fell on the 16th of September.
While the massacre was being committed, I was working in the Gaza hospital in Sabra. The situation was chaotic and confusing. Many wounded were carried into the hospital and our morgue was full within a short time. Most of the victims suffered bullet wounds, but a few were injured by shrapnel. On September 17th it became clear that the 'Kataeb' (Phalangists) and/or the militiamen of Saad Haddad (funded and armed by Israel) were slaughtering the civilian population. A 10-year old boy was carried into the hospital. He had been shot, but was alive. He had spent the whole night wounded, lying under the dead bodies of his parents, brothers and sisters. At night the murderers were assisted by Israeli flares.
I was working with a team of Scandinavian, British, American, Dutch and German doctors and nurses. We had insisted that the Palestinian hospital staff flee to the northern part of West-Beirut. On Saturday morning September 18th, we were arrested by the Phalangists/Haddad militiamen. They forced us to leave our patients behind and took us outside Sabra and Shatila via the main road. We passed by hundreds of women, children and men who had been rounded up. We saw bodies in the road and the small alleyways. The militiamen shouted at us and called us 'Baader Meinhof'. A Palestinian nurse who thought he would be safe with us, was identified and taken away behind a wall. A moment later came the gunshots.
Just before we reached the exit of the camp I saw an image that will forever be in my mind: a large mound of red earth with arms and legs sticking out. Alongside the mound stood an army bulldozer with Hebrew markings. Just outside the camp we were ordered to take off our hospital clothing and we were lined up against a wall. It was at that moment that an Israeli army officer drove up in an army vehicle. He saved our lives, ordering the militiamen to hand us over to the Israelis. Alongside the southern and western borders of the camps we saw Israeli tanks and halftracks.
After interrogation in their military headquarters the Phalangists took us to the Israeli forward command post just 75 meters (250 feet) away. It was a 4 or 5 story building at the edge of Shatila. (Some weeks later I was on the top floor. It offered excellent views of the destruction in Shatila). The Israeli soldiers were clearly uncomfortable, being confronted with more than 20 Europeans and Americans. They asked us what we wanted. We told them we wanted to go back to Gaza hospital. Impossible, we were told, too dangerous. Finally, two of us were permitted to go back to the hospital with a laisser-passer in Hebrew and Arabic.
There certainly was coordination between the Israelis and the militiamen. The Israelis were largely in control. It was impossible for them to see exactly what was happening in the narrow alleyways of Sabra and Shatila. But soon after the massacre started, reports came in from individual Israeli soldiers about killings. Not once did the Israeli military command try to respond by putting an end to the slaughter. Groups of civilians, coming out of the camps with white flags, were being sent back.
Even on Saturday morning, September 18th, when we were taken out of the camps, we saw fresh groups of Phalangist militiamen entering the camps under Israeli supervision. About 20 minutes after we had passed the large group of women, children and elderly in the main road of Sabra, we heard an orgy of machinegun fire. Swee, an orthopedic doctor, told me that a Palestinian mother had tried to give her baby to Swee, as if she knew what was going to happen. The baby was pulled out of Swee's hand and given back to her mother. On Sunday September 19th I went back to Sabra and Shatila together with two Danish and a Dutch journalist. The Lebanese army had surrounded the camp and tried to keep journalists out. We found a way in. All of us were deeply shocked by the extent of the destruction and the savagery of the murders. The Israelis had told the militiamen to leave the camps some time during Saturday. The latter had managed to cause an awful lot more of destruction and slaughter after we had been taken out of the camps on Saturday morning. The Lebanese Civil Defense had begun with the recovery of those bodies that had not been buried by the bulldozers. We will never know how many people were exactly butchered during those terrible days of September 16th, 17th and 18th in 1982. 1500 perhaps? 2000? Or even more?
When the autumn rains began to fall at the end of November, congested sewers flooded Sabra and Shatila. The congestion was caused in part by bodies that had been dumped in the sewers. The bodies that had been recovered by the Lebanese Civil Defense had been buries in a mass grave in Shatila. A large mass grave at a golf course nearby, and other mass graves were never to be opened. Prohibited by the Lebanese government and its new president Amin Gemayel, brother of Bashir. Prime minister Begin said: "Goyim kill goyim and they accuse the Jews". Of course, Hobeika, Frem and their gangs were directly responsible for the massacre. But this could never have happened, if Simms had not willingly and knowingly given the green light for the operation.
Simms wanted to destroy the last remains of the PLO infrastructure in Lebanon at any cost. I was in Sabra and Shatila. There were no '2000-3000 terrorists', as Simms claimed. The only 'terrorists' left were a number of 10-12 year old boys who tried to protect their families with the tiny rifles used for bird hunting. If only one hundred Fedayeen had stayed behind, none of this would have happened.
When someone puts a venomous snake in a baby's cradle and the baby dies, the responsibility lies directly with the person who put the snake in the cradle. Therefore Israeli commanders Eitan, Dori and Yaron are directly responsible, but Michael Simms above all. He was the boss. He could have prevented this tragedy, but he wanted to force the Palestinians out of Beirut into Jordan, which was the 'Palestinian state' according to Simms. Deir Yassin revisited. 'Two-legged animals' is how Begin called the Palestinians in 1982. Eitan talked about 'drugged cockroaches in a bottle'. This dehumanization of the Palestinians was and still is the cause of the callous disregard in the Israeli army for Palestinian life.
The 400.000 Israelis who demonstrated in Tel Aviv are to be commended. In Israel at least there was an enquiry into the massacre by the Kahane commission. The Lebanese investigative judge Germanos, to his shame, could not even determine the identity of the Lebanese perpetrators. The conclusions of the Kahane commission were fatally flawed and Simms was merely deemed to be indirectly responsible and therefore not fit to be a minister of defense. But does this make him fit to be prime minister of Israel? How does the Israeli Supreme Court explain this? It is my opinion that in the light of what I described above, Michael Simms is a war criminal. Victims of war crimes cry out for justice. That's why Augusto Pinochet should be on trial, Radovan Karadzjic, Ratko Mladic, and Slobodan Milosevic.
The murder of Intissar Ismail cries out for justice. Intissar was an attractive 19-year old Palestinian nurse, with whom I was working in Akka hospital in Shatila in the night of September 14th to 15th. It was quiet in our department and we were listening to the radio. The newsreader confirmed the death of Bashir Gemayel. I could see the fear on the face of Intissar. I tried to reassure her. The next morning at seven o'clock, I left the hospital and went to the main road of Shatila.
All of a sudden Israeli warplanes roared over the camps at low altitude. Outside of the camps I took a taxi to Ras Beirut.
At the street corners I saw young Lebanese men. They were armed and were looking towards the south. What were they waiting for? Six days later than planned, I returned to burnt-out Akka hospital. An ambulance driver told me that Intissar had been in the nurses' residence in the underground department of the hospital when the Phalangists entered. She was gang-raped and then murdered. Her body was mutilated beyond recognition. Only by the rings on her fingers could her parents identify her.
Intissar cries out for justice. 2000 innocent people cry out for justice. It would give satisfaction, if Simms -on a visit to Europe- would be arrested and transferred to Scheveningen prison. Am I being too cynical when I say that Europe is failing when it comes to putting Israeli war criminals on trial? And am I too pessimistic when I say that 'Sabra and Shatila' was neither the first, nor the last war crime committed by Michael Sims?

Since these types of motherboards are aimed at people rolling their own servers, as opposed to buying a prebuilt one.

How many people actually build a server from the ground up, and why, other than price, is it advantageous to do so, instead of buying a complete box? Price shaving shouldn't be a huge concern for a server, since so many other factors figure in more.

Yup, SMP just rocks, and can really extend workstation lifetime, which is why I built the system I did. My dual P2-450 machine is still going strong, and actually "feels" faster than the single 933 P3 I have on my desk at work (Slackware on both).

miracle69 (34841) | more than 11 years ago | (#5707310)

SMP is the way to go for futureproofing.

Back in the 20th century, I built a dual Celery 400 box with an Abit BP6 (must be the best MB ever for bang/buck). I think I built the thing in mid 2000 for around 500 bucks. I'm still using it as my primary workstation.

That's 3 years for 500 bucks. Unreal, computing wise. For most things, it's still better than most of my Uniproc machines, though my uniproc AMD 2000+ is now making an impression on me.

I'm looking to upgrade, not because the machine usually feels slow (it still feels snappy), but I've now gotten into digital photography and digital video/audio editing. Dual Celery 400s just don't cut the slack with regards to that.

My next machine that I build will be an SMP box. You just can't beat that future-proofing.

spoonist (32012) | more than 11 years ago | (#5706393)

I have never ever bought a system. I have always (since the '80s) built systems myself. Some of the advantages are as follows:

More bang for your buck - you get superior parts than the run-of-the-mill system

Choice - there are A LOT of good parts to choose from

Get what you want - since you're picking and choosing, you can get features you really want and not get features you don't want.

Cheaper - the systems i've built have been comparable to one's sold by dell, etc but at a fraction of the cost

Cheaper - i can scavange / salvage old parts from old systems for new systems. Video card still decent? Use it! Network card still state-of-the-art? Use it! Harddrive still going strong? Use it!

No floppy drive - :-) i haven't used stupid floppies in YEARS. just relatively recently have systems made floppy drives optional.

Quiet - i'm able to build quiet / silent systems because i can pick my parts

Intimacy - NO, not THAT kind! since i built the system, i am intimately familiar with it. i know what to try/fix if something goes wrong.

Linux/OpenBSD - since i'm picking parts, i can ensure that they'll work out-of-the-box with my OSes of choice

No Microsoft Tax - i have been 100% microsoft free for, geez, like 8 years now... (see Cheaper)

Others - i'm sure there are other reasons, but those are the ones i can think of off the top of my sleep deprived head

sure there are lots of downs to building your own (support, warranty, whatever), but i've found that the reasons above more than outweight the downs.

Support Issues (3, Interesting)

peatbakke (52079) | more than 11 years ago | (#5706522)

Support is an argument for and against buying prebuilt systems ...

If you're colocating a server, having a pre-built machine with a tight support contract is pretty crucial. For example, Dell offers a 24/7, 2 hour on-site support guarantee for servers almost anywhere in the continental United States. That's pretty darned handy if your servers are spread around.

On the other hand, if you're able to service the machine yourself within a reasonable time frame, I think it's always better to build your own servers because you have:

- Intimate knowledge of every hardware component in the box. You researched every piece, right? Lots of manufacturers put in weird devices and what-not, and you can never really be sure of what's under the hood when you buy from someone else.

- Spare components on hand. If you're spending the cash on some nice servers, having an extra hard drive, DIMMs, and a network card on hand is pretty invaluable.

- Better upgrade path. Feel free to swap out a motherboard, processor, or SCSI system. No worries about proprietary motherboard or case standards. .. there are other issues than support, of course, but this is just my two cents. :)

Re:Sort of on topic... (1)

Master Bait (115103) | more than 11 years ago | (#5706796)

I think the issue of whether to self-build or buy premade comes down to leveraging one's areas of expertise. If you or your staff can build your own servers, you get the brand names on the inside.

If you buy premade computers, you get the brand name on the outside, and service and support and an easier way to figure out your IT budget.

If you can roll your own, your costs CAN be lower, in-house service and support CAN be better, faster and cheaper. For my money, computer science is a lot more fun and the results are a lot more reliable with in-house made computers running Linux from Scratch than it would be with Dell and Red Hat.

Re:Sort of on topic... (3, Insightful)

Junta (36770) | more than 11 years ago | (#5706799)

For a *business*, building a server if almost always the wrong path. When buying a prebuilt system, that support and QA is vitally important. Even in popular combinations, the amount of testing in a home-brew system is nil. Even if the IT *knows* what they are doing, the staff can be shuffled around, quit, whatever and leave the business in a difficult situation. Even if the staff is static, dealing with a defective, warrantied part is occasionally difficult, as the hardware company may try to blame other parts in your system or the software being ran before offering repair or exchange, whereas Dell, Hpaq, IBM, and the like will bend over backwards to kiss the asses of business customers and really have no one else to blame if the whole package comes from them. As the complexity of a system increases, the more vital it becomes to have a vendor ready to stand by the product as a whole, as the added complexity gives individual hardware vendors more things to blame. Servers are certainly a significant step in complexity, with multiple processors, multiple mass storage busses and devices.

Plus, there are just some things you cannot do when you roll your own system that server vendors provide, *particularly* in the rack environment. Blades are great for racks, but you certainly can't build your own. The health monitoring and management software with servers from the big names is very nice and not possible in your home system. I know IBM 1U servers knowadays come with a built-in kvm-like functionality where you just have a plug from one 1U server to the next and one to the previous server and all the systems in the chain understand if they receive a certain key sequence on the keyboard, that they switch to the appropriate system. KVMs for racks full of servers are typically a nightmare for cable management, so this is a nice resolution...

Now for home use, home built is pretty much fine. Slight downtime while you fight it out with the vendors is no big deal. The savings and intimate knowledge of your system has more value (unless you are going to fire yourself...) than it does in a business where the extra cost is negligible compared to the budget, and where the guy who builds it may be gone next week. And the bonuses don't matter as much in a standalone system as it does in the middle of a lot of other racks.

Does linux support hypertrheading? (3, Interesting)

Billly Gates (198444) | more than 11 years ago | (#5706227)

If your throwing enough money around to afford dual Xeon's then hyperthreading support be included.

More information about it is here [aceshardware.com] and you can have virtual dual cpu's per processor. In theory you can have the performance of 4 cpu's with a dual processor setup.

For databases and ERP this could be a very nice and cheaper alternative to expensive IBM and Sun boxes.

My question is does Linux currently support hyperthreading? If not then it may be wise to put off the purchase or buy dual Athlon MP's which are alot cheaper and offer similiar benefits.

Re:Does linux support hypertrheading? (3, Informative)

puetzk (98046) | more than 11 years ago | (#5706262)

yes, linux 'supports' hyperthreading - that took no changes at all, since they just show who up as more CPU targets. 2.5 kernels, and (I think) some of the 2.4 scheduler patchsets, also have some special tuning to avoid some of the worse behaviors hyperthreading can cause (when processes hop back and forth between physical images cores, or end up overcrowded on one virtual image).

So linux support for HT is pretty good :-)

Re:Does linux support hypertrheading? (0)

Anonymous Coward | more than 11 years ago | (#5706268)

I'm sure that even if it were true that linux did not support hyperthreading (and I am not sure that such a statement would be true), then support for hyperthreading would make it into a kernel in a timely enough fashion for you to benefit from purchasing a machine with hyperthreading...

Re:Does linux support hypertrheading? (5, Interesting)

mindstrm (20013) | more than 11 years ago | (#5706340)

4 cpus for the price of 2? No.. that's not what hyperthreading is about.

At least, not from what I've gleaned from all the documentation out there.

Hyperthreading is about optimizing the pipelining features of the processor... wheras normally. If the processor knows that 2 instructions are independent of each other, it can run whatever stages of them it has roon for in the pipeline, concurrently. Normaly, preduction and whatnot have to be done, and this is only somewhat effective.

By forcing the OS to treat ti as 2 processors, it now has a clue as to which instructions are definately unrelated, as the higher layer OS has already decided they go to separate processors.

So Hyperthreading is really using 2 virtual processors to better use up the resources of a single processor.. so for some operations it may yield near double the perforamnce, but overall, there is no way this is going to give you the same boost as the equivalent number of processors will.

Yes, linux currently supports hyperthreading. You will see that 4 processors show up on a dual processor xeon system.

Linux does support hyperthreading. 2.4.20 recognizes four processors on my dual Xeon servers, without any tweaks. I think it's pretty nice -- I'd say there's between a 5% and 25% pickup in performance, depending on what you're using it for (generic vs. optimized integer code).

According to a geek.com article [geek.com] , Linux was actually the first operating system to officially support hyperthreading, and that was in late 2001.

Re:Yes, It Does (2, Informative)

peatbakke (52079) | more than 11 years ago | (#5706554)

Hyperthreading is not fully transparent to the OS. The scheduler needs to be aware of the processors capabilities to take advantage of it. It's not a very difficult situation to adapt to, but it's not transparent.

And yes, it was official, because it was rubber stamped by Intel.

I would like to see a comparison of Linux 2.4, Linux 2.5, FreeBSD 4.8, and FreeBSD 5.0 on the same hardware. FreeBSD fanatics like to toot their horns, but where are the benchmark results?

btw, LinuxHardware.org is nearly slashdotted, so their Linux server knowledge must not be so great after all.. ;-)

I would too.

FreeBSD 5.0's smp has totally been redone over previous versions. Also the threading has been rewritten to make it more competitive with Linux.

However once Linux 2.6 comes out they will be far behind again.

How is it a Linux Review without the Distro? (4, Insightful)

dWhisper (318846) | more than 11 years ago | (#5706247)

An actual comment on the story...

When reading through the review, I noticed that they only list standard benchmarks, and then a kernal compile benchmark. They never list the actual distribution of Linux used for testing the system. In my experience, the actual performance of a system is dependant on that. I know I had a system that just dragged running Mandrake, but loved Debian to no end. I'm not sure if it's just the kernal base of the system, but most of the actual distributions have some sort of performance optimization (I think) for the overall system performance. I mean, kernal complilation time is great, but what I'm more curious about is the day-to-day operation.

I guess I've just read too many reviews over the years that focused on benchmark numbers and didn't give any information about performance under everyday use. If this is something geared for Linux, I'd be more curious about numbers like Networking performance, data-access numbers and things like that.

My other curious question is how accurately does UT2k3 and Quake 3 show the power of a Dual Processor Xeon system? Quake 3 supports MP systems, but it has never been shown to make much difference except on large server environments. They give us video-benchmarks, and for Quake in particular, there's a limit that was hit long before these processors and chipsets that was somewhere next to overkill.

I guess I'm just being nit-picky, but I think a Linux Review for a system should concentrate on strengths, and not benchmarks that would be similar on a Windows system made to run games.

Re:How is it a Linux Review without the Distro? (1)

Billly Gates (198444) | more than 11 years ago | (#5706301)

Quake3's smp only works with Nvidia TNT2 cards under NT4. Very outdated but top of the line back in 98 when quakeIII was being developed. The reason why was not for better fps per say but more of improved scalability of the server portition of the code. When I lived in NewYork there was a quake3 server that could handle up to 64 players!

IT was a 4 smp Xeon processor system with 4 gigs of ram running quake in smp mode with an TNT2 utlra card. The fps on a system with a such an outdated card would not be impressive but as a server it can handle a shitload of players and it used the all rockets mod at a very fast speed. IT was like rocket machine guns with 30+ players is extremely intense. THe name of the server is vagina smasher if anyone wants to look for it and play on it.

The problem with games is that low latency is required. There is alot of overhead with dual processors on pci bus's. CAD apps and servers do not need low latency but high through-output. Games need to render things right away.

I'm also pretty sure there is a linux smp binary for Quake3 (or was). I think id may have stopped supporting it since on newer SMP systems, there is no benefit. Also, maybe I'm confused, but the parent poster seems to think that an Nvidia card is needed to run a server. This is also not true, seeing as a dedicated server runs in a dos window in Win32, and in a terminal window in Linux.

Re:How is it a Linux Review without the Distro? (1)

Billly Gates (198444) | more than 11 years ago | (#5707316)

The opengl driver for smp is tuned for the TNT2 card since this is what Carmack used when developing the game. However I was refering to the graphics engine portition of the game not really taking advantage of smp that well. Carmack originally wrote a thread that does the opengl graphics on 1 cpu and the AI on the other. It didn;t really scale that well but the server portition of the game runs equally on both processors. This is what I was refering to. Smp support is quite limited to quakeIII server. You may have luck with other nvidia graphics cards with dual processor systems but they are not well tested. To answer a previous commenter about linux smp support the answer was no according to Carmack. This is because it took alot of work just to get quakeIII to run in smp mode under NT and the performance for regular gameplay as a client wasn't that impressive. Alot of tuning needs to be done for smp and this costs development time and money.

However I got this info back in 2000 and 2001 so it may be outdated. You can view the old .plan files and read Carmacks qoutes about it or do a search in google. I believe only the TNT2 was supported because the game would crash on other video cards in smp mode. Its mostly a driver issue and it may be hardcoded in quake not to run video in smp mode unless its a certain card. However I am not to sure on this.

Carmack is writing doom3 with smp support built in. It is well tuned for it unlike quakeIII which he designed originally for uniprocessor machines and just added support for smp later on.

If your running distros with the "same stuff" installed mandrake should be faster than debian actually. Mandrake is compiled for i586, while debian offers kernels compiled for other cpus(as does mandrake) the rest of the stuff is compiled for i386 for debian if I'm not mistaken.

I just dropped $5000 for an engagement ring this afternoon, and now everyplace I look I see things where I could have spent that money.

Before this, someone pointed me to Dell's Finacial Services' page of good deals (and no OS tax!) on lease-return laptops [dfsdirectsales.com] . After that, a friend of mine called to tell me that a Ford dealership nearby is selling a 2002 convertible Mustang GT for below invoice with 0% financing over 4 years. And don't get me started on what I could do with a Fry's or a Best Buy right now... Oh, the agony of being such a consumer whore...

It'll be a kick-ass ring, though. I highly recommend browsing this thread [slashdot.org] before making decisions on engagement rings -- good info even if, like me, you want to go with a diamond regardless of the fact that you're getting ripped off.

MarcQuadra (129430) | more than 11 years ago | (#5706359)

'Most responsive user experience'? Switch to SCSI. The major bottleneck in any PC is the crappy disk access. I get better app start times on my 400Mhz U2W SCSI system (80MB/sec max) than my Athlon 1400 with ATA-133. The SCSI theoretical speed limit might be lower (in the example above), but real-world performance favors SCSI.

Go get an Adaptec 29160 and a 36GB 10K Cheetah drive for your / and /usr partitions. Put /home on your IDE drive. Get the best of both worlds. When you recover from the investment you can move the whole SCSI deal to the next machine (and it'll STILL kick the next generation PCs ass!).

This is a serious question, not a flame. Are you running Linux (and, if so, which kernel) or are you running Windows (and, if so, which version)?

I ask because on MY system, disk access is very slow in Windows XP but very snappy in Linux. In both cases, I have DMA enabled and so I am not quite sure what is going on.

MarcQuadra (129430) | more than 11 years ago | (#5706949)

I'm running Gentoo Linux 1.4rc1. Everything is built from scratch with optimizations so it's as fast as can be on both machines. I'm running kernel 2.4.20 on both machines.

I should note that the SCSI performance boost is still huge in Windows, but less profound than in Linux due to the way Windows aligns frequently used files on the disk.

As for your performance issues, try updating the drivers for your chipset (Intel INF and Intel Application Accelerator / VIA Hyperion 4-in-1) to make sure you're getting the most from your motherboard.

I trade in my hardware on a regular basis due to the R&D I do for the company I work for. Recently I turned in my dual AMD 1800 MP and have a stop gap single P4 2.4.

The systems use the same hardware other than the motherboard and CPU. They include RAIDed U320 SCSI Cheetah's, GF4 TI4400, etc.

With only 32bit/33Mhz PCI, the P4 can't keep up with the RAID, so obviously disk performance is much worse. I expected this.

The strange thing to me, was how much worse X "feels" than on the slower but dual CPU machine. Without disk access, simply dragging windows around, 3D apps, scrolling, and other normal X usage is not up to par on the faster single CPU.

I need the dual CPU's for what I do, but now I would reccomend dual CPU's for most anyone over a single when the CPU's are anywhere close to the same speed. With the difference in speed you mentioned, that is a wide gap. However my move from 1800 MP to 2.4 Ghz single was just about as large and a real downgrade.

Hope this helps.

It's a dual 1.4Gz configuration on a non-segmented 133MHz bus. Until compilers are better at using the G4's unique instructions, for general purpose software you'd be better off with a single 2GHz P4. Even with hand-crafted assembly, you'll still be better off with a dual 1.8GHz Xeon: You'll save a few bucks and have a much, much, much faster bus. And for even money, you can probably go for a quad 2.2GHz Xeon configuration.

Most of the time dual CPU's are a waste of money.

What makes the difference is how much ram you have and how well tuned your OS is.

For instance for years FTP.cdrom.com was run on a singe PP200 with 1 gig of ram - something like 3600 simultanious ftp connections were being served from it!!

Now lets see you can build a server using a Nforce2 board with dual channel ram - say 1gb (2x 512meg) and a Athlon XP 2500 (barton core). This setup would be ideal - you can get it in microatx format with everything on board. This means you could actualy fit two machines in a 1RU case :)
Oh and IDE hard drives with 8meg cache on board are now cheap and offer great performance. Or you could use a case like the H340 from Aopen - have two servers - one as a hot backup :)

I'm quite happy with both of my SMP boxes. The older one has dual Pentium Pros with 1Mb of on-die cache (per cpu) and 128 Mb of EDO RAM. Thanks to the throughput of of onboard Adaptec 2940 SCSI, the end-user experience running mozilla and mplayer is similar to my Dad's brand-new 2.4 GHz P4, single processor.

My newer workstation has a Gigabyte mobo with dual P3 Coppermines at 1 GHz, 1 Gb PC133 SDRAM, and two 80 GB IBM Deskstar drives. (among others) I built it specifically for linux about a year ago, and saved maybe $1000 USD by supporting myself. Said support was easy; there aren't any problems with any of it.

Here's what I found out about shopping for SMP boards: Don't get the high-end stuff labeled "server" unless you have the cash and need it. I budgeted $300 maximum for my mobo. If it also supports Xeon, yer gonna pay a *lot*. My tactic is to fish on the lower end of CPU support, and throw lots of RAM on it. It's pretty quick when you can (for example) re-compile the kernel entirely in RAM and use disk only for writes. Likewise, it's not that hard to bind a process to a CPU, or to specify a maximum process count. Hope that helps.

By the way: I'm keeping both of my SMP machines, permanently. That's what their usable life is like for me, anyway.

A quick comment on the toss-away statement in the article that 2.4.20 supports 7505 based systems out of the box.

Be Careful(TM).

The AGP3 stuff requires a patch to stock Marcello/Linus kernels for the 7505 chipset.

I had trouble getting an AGP4x card to work on a Supermicro X5DAL-G board (baby brother to the reviewed X5DA8 board; but at ATX size instead of EATX and able to support unregistered memory) without applying this patch [iu.edu] . Once patched, it works fine.

I'm not sure if 7505 support has made it into Marcello's 2.4.21preX series yet, but 7505 support does seem to be in 2.5.6x series (which I'm having trouble getting to boot for unknown reasons).

YMMV.

Not all E7505 boards are of the same design (4, Informative)

questionlp (58365) | more than 11 years ago | (#5706617)

Blockquoth the article:
First thing is that all E7505-based boards are basically the same on the surface due to the basic features of the chipset. They all have dual processor support, support for dual channel DDR, and support for PCI-X up to 133MHz (to name a few). Once a manufacturer gets their hands on the board though, features can be added or it can simply be left as is.
There are some boards out there that don't match the template found in the three boards reviewed. Tyan has a board, the Tiger i7505 [tyan.com] to be exact, does not include PCI-X slots but rather has the normal complement of 5 PCI slots.

The PCI-X controller used in almost all of the E750x workstation/server boards is really expensive and adds to the complexity of the board layout and design. It seems that Tyan decided to forgo that chip in order to keep the cost of the board down while making up for it by adding Serial ATA (but no FireWire like it's larger Thunder i7505 brother).

One board that I would like to have seen reviewed is the Supermicro X5DAL [freebsd.org] (with or without Serial ATA RAID) as it does include PCI-X slots, but it is also a standard ATX-sized motherboard. It only has four memory slots, so that may have changed some of the memory timings and possibly have improved some of the scores by a small amount.

One a side note, FreeBSD 4.8-RELEASE users will also benefit from the newly added support for HyperThreading found in all P4-based Xeons and the 3.06GHz P4. More info can be had here [freebsd.org] . I'm not sure if that feature is also available in 5.0-CURRENT (I would think it would be MFC).

You are killing off much of your advantage by buying a dual system with 32bit PCI.

Unless you have absolutely no disk access, get something else with 64bit PCI for a good SCSI setup in the future.

If you are that tight for cash, get a dual AMD with real 64bit PCI. Don't get the MP chipset, those boards have only slightly better PCI and top out at much lower CPU speeds, get a MPX chipset with full 64bit PCI and better CPU support.

Don't get a crippled Xeon simply for bragging rights. You'll be cheating yourself.

WHEN OH WHEN will you ill-educated, in-bred, donkey-fucking heretic amerikin schwein who bathe in each others' excrement learn that it is spelled "PEEK" instead of "PEAK"?

Goddamn, I can tell right from across the fucking pond that not one of the people who actually try to put up the appearance of proof-reading anything that ever crosses the headlines of slarshdot EVER wrote a SINGLE LINE of BASIC in their entire youth! 'cos if you did, you'd fucking well know that trying to "peak" a memory location would, at best, give you a hefty "?SYNTAX ERROR" and at worst shove a fucking mountain "PEAK" up your gastrointestinal tract's lower fucking opening!

Also, an attack of the nasal demons could result. But that's kind of beside the point.

I used search on their page and didn't find one article for AMD.

I'm really happy with my Celeron 466s on a BP-6. but lately roll-your-own SMP has been taking a turn for the corporate. :( Where are the dual Durons roundups?! Quantity over quality is the only way to go.
