US Army Needs Linux Workstation Advice

Cliff posted more than 14 years ago | from the suggestions-anyone dept.

Linux 391

Shawn wrote in asking for suggestions on high-end Linux Workstation configurations for the US Army. Aparently, they are looking at replacing some SGIs with cheaper PCs, and this being Slashdot, I'm sure some of you might be able to make some improvements to their suggested configuration. I can't tell you how glad I am to see the US Army giving Linux a chance. The US Navy could probably learn a thing or two from this. Click below for the full text.

Shawn asks: "The US Army is looking for advice on purchasing several high-end Linux workstations. These systems will be used in a post-flight processing environment. We routinely process raw data measurements in excess of 1 million samples/second. This processing can utilize several GB of disk space and up to and exceeding 1GB of RAM. We are currently using SGI Octane systems but need to switch to the lower cost PC environment. This will allow less costly while still providing excellent performance. Let us know any advice you may have or insights we may not have thought of.

Here are the specifications we are currently considering:


  • Intel® 840 chipset
  • RIMM slots for at least 1GB dual-channel Rambus® memory
  • Integrated dual ATA-66 EIDE controllers
  • Ports: USB (2), serial (2), Parallel, PS/2
  • Integrated Ultra 160/M SCSI and Ultra/Wide SCSI Controllers
CPUs (2)
  • Intel® Pentium® III 733Mhz (slot 1)
  • .18-micron Coppermine architecture
  • 256K cache
  • 133MHz FSB
  • 1GB Rambus® memory
  • Full tower
  • 300W or greater power supply
  • 4 or more 5.25" exposed drive bays
  • 1 or more 3.5" exposed drive bay(s)
  • Two or more small fans blowing air directly across the drive bays
  • 9GB Ultra 160/M SCSI (7200 rpm) hard drive (internal)
  • 36GB (or larger) Ultra 160/M SCSI (10000 rpm) hard drive (internal)
  • LS-120 internal superfloppy (IDE)
  • 5X (or faster) DVD drive (internal - IDE or SCSI)
Video Card
  • Diamond Viper V770 Ultra 32 (AGP 2X/4X)
  • Viewsonic P815 21" monitor
  • 3Com 3C905B-TX ethernet card (PCI)
  • SoundBlaster PCI128 (PCI)
  • Powered speakers with wall adapter
  • Soft-touch keyboard (no keyclick)
  • Microsoft Intellimouse
  • Red Hat Linux 6.x
  • 3 year parts and labor

If you're really looking for speed, why not try a 64-bit processor? Alphas or Sparcs, both are very fast, especially Alphas. They run linux well, and are fairly stable. The only disadvantage is you would have to port the code by making sure that it's 64-bit clean.

Anonymous Coward | more than 14 years ago | (#1438372)

Some of those Sound Blaster 128's do not work because of randomly changing codec chips... I have an es1370 (also Creative,very similar to SB 128). The SB Live card has Creative's official blessing in the form of open source drivers from the manufacturer. Also, I like the DEC Tulip based cards; Bay and Linksys both make one. 3Com also charges 2x what their competitors charge due to name recognition. Otherwise, this system looks awesome.

Watch out for the backdoors in the Intel CPU's. (3)

Anonymous Coward | more than 14 years ago | (#1438373)

Avoid the Intel CPU's. The AMD K7's outperform the Intel Pentiums, anyway.

Since this is a government bid, presumably security is a concern. The problem with the Pentiums is that the CPU microcode can be changed
on you, and you'd never know it.

This problem gets even worse with the Merced/Itanium/whatever-the-64-bit-chip is called.

With the embedded crypto, changeable microcode, and the moves to integrate ethernet on the motherboard, the 64-bit CPU will be wiretap ready.

This is presumably why the Chinese have moved away from the Pentiums, and Europe appears to be heading in the same direction.

The K7's don't have this problem. Nor do the PPC, or the DEC Alphas.

The US military is in the business of invading foreign nations and imposing their rules on the rest of world. The military are the thugs who backup the politicians who come up with grand philosphical reasons to extend the scope of control of the US economy to include the entire world.

While I can't disrespect these boys who are eager to "play guns" for real, they do little worthy of respect.

Americans are hated all over the world, almost universally. Why? Because they've bomed more countries than anyone else since WWII, and because they've got soldiers on the soil of soveriegn nations. Your saying American soldiers are "just following orders." Now where have I heard that before?

Anonymous Coward | more than 14 years ago | (#1438387)

A nice setup, but here's a couple of suggestions: * Was that two processors you were considering? Perhaps push it to four. * Consider getting a redundant RAID array if this is going to hold terribly important data. * Make sure there's no chance of this system getting overheated. Don't spare the cooling fans. And get one of those temperature LCDs/warning alarms that mounts onto a 5.25" bay. * Redhat is great, but also consider SuSe 6.3, in Best Buy for about $25. Lots of great stuff on those CD ROMs.

Typical overkill (3)

BranMan (29917) | more than 14 years ago | (#1438388)

Sometimes this kind of stuff just irks me - how clueless are people anyway??

This is a DATA PROCESSING machine. You do NOT need a 128bit sound card plus massive speakers. If any kind of sound is going to come out of this thing, an average SB16 or AWE32 is more than adequate.

You also do NOT need a Viper 770 video card. What the heck are you going to display on your screen that you would need 32 Mb of video RAM for?? Just an ordinary video will do - 8Mb at the most. This is X-Windows, not Quake.

No need to specify UltraDMA66 controllers if the only thing you're going to hang off it is a DVD drive.

The Athalons will still give you a few percent higher performance on math than the PIIIs, you may want to go with that instead - though you may not have much pick of motherboards.

Other than that, looks like a darn nice set of specs.

Everything looks pretty tasty but currently the

Right now 3dfx chipsets have the best support but are pretty much maxed out potential wise.
I would suggest looking at Matrox G400 instead.
Matrox has been very good about releasing specs
and the current driver outperforms the TNT2 in terms of framerate by a considerable amount.

Anonymous Coward | more than 14 years ago | (#1438395)

I think you would get better bang for the buck if you went with 2 - 4GB of SDRAM. If you want speed, you absolutely DON'T want swapping. 2GB SDRAM should cost about 1/4 as much as the 1GB Rambus...

Also, I don't know what your exact application specs are, but the video card is overkill if you aren't doing 3D. A Matrox G200 would work just fine.

side has a lotta guns and troops and APCs and all kindsa stuff. So you, being the punk ass loser that you are, quit the game and go out and get some sushi or a burger or something. It's like
that with the "invaders". They take a gander across the Atlantic Ocean or the Pacific Ocean (those are two very large bodies of water on the east and west sides of the US) and they see planes

By the way, where are all the SMP Athlons? A year ago everyone was saying "by the end of 1999," but I see none. Going from a K6-2/450 to Athlon/550 nearly halved the time to compile things. I can't wait to reap the benefits of two of these suckers.

Anonymous Coward | more than 14 years ago | (#1438399)

Call it a personal quibble (which is why I'm posting this annonymously), but I'm not so hot about the Army's choice of Wide SCSI as a backup option; while recent builds have allowed for more stability, the bus has been a total nightmare for myself & a couple others I know (and that was just with standard SCSI!) The thought of high-volume memory storage on Ultra-Wide for something as serious as Army applications (field engineering and disaster relief, commumications relay & reconnaisance, etc.), coupled with the tendancy of hardware drivers to collapse after less than a full year's install on some builds makes me shiver.

Myself, I'd run Linux with Solaris on an array of Alphas for the SCSI tasks. But that's just my unpopular opinion.

Mixing IDE and SCSI (2)

Setup (5)

debrain (29228) | more than 14 years ago | (#1438402)

It's difficult to say what needs to be changed when I'm not entirely sure what the specific application setting is for this piece of equipment.

If it is specialized, I would recommend a simple window manager such as BlackBox or IceWM. There is no need to burden your system with unnecessary tools and applications. If, on the other hand, it is going to be a user friendly system, I'd have to recommend using KDE or GNOME, giving preference to your personal aesthetics. The added complexity of GNOME or KDE should be justified.

In terms of hardware, I must point out that USB support will not be available until kernel 2.4, IIRC, but that will be arriving soon. Also included will be firewire support, again IIRC, which should encourage you to investigate using that as a possible alternative to SCSI. Again, it is application dependent, and also subject to some personal preference.

In terms of video, the Diamond Viper is a bit of overkill if you'll be using BlackBox or IceWM, and you could save yourself a bit of money by getting something a bit less hefty, and possibly including TV support, such as the ATI Rage128. Since the TNT2 chipset is being backed by NVidia under Linux, it is a decent choice, IMHO.

With respect to the processor of choice, I see no real reason not to get an AMD instead of an Intel if the price is right and the speed is sensible. Alternatively, with Linux, you can go completely Alpha, or Sparc (although I would avoid Sparc, but that's a personal aesthetic thing), and not have to really worry about interoperability with other platforms given the nature of Linux.

Well, I hope that helps.

36 GB SCSI drive: Why not go with a RAID 5 array?
Use a nice Mylex RAID controller.

Number Nine Video: Bah! Get Voodoo3, baby!

DVD drive: I don't see the point in having a DVD
drive since the DVD consortium is being openly
hostile to the Linux community. CDROM drives are
still more pratical at this stage in the game.

Misc Advice: If you're going to buy 10 exact
duplicates of this machine here's how to make the
install easier/faster on the other duplicate

1. Make the hard drive a single partition. You
shouldn't need a swap partition with 1 GB RAM.
OK, you may need one swap partition just to be

2. Install the OS, then install all the drivers
like the Voodoo driver, and the SB Live drivers.
Setup X just they way you want it. Install all
your favorite software.

3. "tar -xfp" the entire hard drive from the
root directory down. Copy this tar file onto
a CDROM disc.

4. On the other machines, boot from a linux boot
disk, partition the hard drive, pop the master
image CD in the CDROM drive, untar the master
image file onto the hard drive. Run lilo to make
the hard disk bootable.


Wanderer1 (47145) | more than 14 years ago | (#1438412)

SMP is a good idea, if your application is calculation-intensive. If it is merely I/O intensive, then you have another ballgame.

RAID is a good idea for I/O heavy traffic, when that traffic exceeds the capability of a single disk. Caching is an option, but we're looking at a constant stream of new information, rather than reusing existing information. Thus you want a pipeline which can deliver data to the final medium (disk) quickly without eating up additional CPU cycles or unnecessary I/O bandwidth.

RAID-0 is a good choice in this case, with a hardware-based controller and 4 or 5 drives. The data is streamed to the controller at speeds approaching the bus limit, and the controller fans out the load to individual drives without any system overhead.

I don't believe data-guarding (mirroring or parity) is warranted in this case. A workstation does not need 24/7 uptime, and I doubt the application would be able to "pick-up" where it left off if a fatal error occurs. Plus one would expect the products of this process to be backed up immediately to another medium, rather than left on harddisks.


Defending the Intellimouse (2)

Frank Sullivan (2391) | more than 14 years ago | (#1438413)

Actually, the Microsoft Intellimouse works very nicely under Linux/XFree86. I recently used one on a Netfinity at work because i knew it could be used as a three-button mouse, and it was handy. To my pleasant surprise, i found out that the wheel also moves an xterm scrollbar! What a great feature!

But a DVD drive? Um, guys, they aren't really supported well yet.

PC's and Linux/Intel. (2)

richnut (15117) | more than 14 years ago | (#1438416)

I think Linux is an excellent match for a place like the Army as they have tons of resourc3es to maintain their own internal code fork to fit their own internal needs in the most reliable way. Not to mention that internal expertise on the OS would make important defense systems easier to fix and extend in times of crisis. OTOH, nothing disturbs me more than using Intel based machines for such a venture.

Intel is nice and all for toys. But even imagining an Intel based machine in the hands of an Army programmer who needs to fix code or people die, really scares me. I've used a lot of Intel based machines in my life, and almost all of them were crap compared to their custom-built UNIX counterparts. Their components fail far too often, their archetecture is woefully un-scalable, the interchangable parts of a PC make it hard to get an effecient system case for cooling or for ease of maintenance, they make poor use of space, they're ugly, and their build quality is sad at best. Incedentally most of this isn't Intel's fault, it's just the way the crumby boxes are designed. They sure are cheap though.


Re:Net card... (a bit off topic) (1)

billh (85947) | more than 14 years ago | (#1438417)

I use a number of Tulip cards, but I've had a hell of a time getting the things to stick on 100 instead of 10. Maybe it is just my 10/100 switch, but the Windows machine on my network is the only one that will consistently hold 100.

Has this problem been solved? I haven't checked in over a month, but last time I did I pulled down the latest driver, read the FAQs, recompiled, etc... I still can't get anything but 10 reliably, and when I do get 100, I get so many lost packets that anything more than a telnet or SSH session will die on me.

Interestingly enough, my laptop with a 10/100 3Com card comes up 100 every time. Although RH 6.1's netconfig dumps core each time I use it, it still brings the card up just fine.

The business of the Army (2)

jabber (13196) | more than 14 years ago | (#1438418)

The business of the Army is to protect your rights to anonymity (posting as an AC), and free speach (posting as an AC), and liberal technology use (posting as an AC), and maintaining the US in a position that allows you to have an enjoyable standard of living (posting as an AC).

Their presence, and successful killing of people who would otherwise be running your life, is what provides for your right to choose to be a pacifist. Their existence is also what provides for your right to not contribute to their efforts. Were it not for someone standing guard, you might be tortured into providing the desired information against your will.

Being an immigrant, I fully support and appreciate the US armed forces. Thanks to them, dissidents and people with unpopular (non-state-sponsored) views have a chance to be heard. They even have an opportunity to spew their self-righteous opinions without spending more than two seconds thinking about their validity. Their only fear of retribution being that of someone else exercising their own God and Country assured right to free speach and a differing opinion.

Companies, and some advice. (5)

MAXOMENOS (9802) | more than 14 years ago | (#1438422)

I'd recommend the following companies:

The first three companies are pure Linux. The fourth is getting good advice on Linux systems from people in the community.

You absolutely want as little variation on your hardware as possible with these machines. This will up the price of each machine. However, it will also make them easier to maintain, repair, upgrade and find drivers for. The additional expense pays off in the long run, if you are going to deploy thousands of these things. Make this a condition of your contract.

Personally, I say go with ASL, if only because they're nice guys.

NB- I don't work for any of these companies, even (as far as I know) indirectly.

OnyxRaven (9906) | more than 14 years ago | (#1438428)

Looks as if you have a good idea of what you need, or is it what you want? make sure you NEED all that processing power, super-expensive Rambus memory, and ultrafast video card.

I have a feeling this sounds like a storage machine - means you should have a good amount of ram, but regular PC100 or PC133 will work fine. Dual processors? maybe, if you are doing stripeing or mirroring with your disks.

Also don't limit yourself to RedHat - remember redhat is not linux - you can go ahead and look at debian, stormix, mandrake, suse, and the rest for a distribution that fits your needs, or one that just spikes your interest. (I personally like stormix)

if you can get past the windows mentions, look at the god-box and the other boxes over at Ars Technica [] . They have some great reccommendations on good value hardware.

Lastly, i saw a few complaints about the 3c905b cards in earlier posts. We religiously use these cards (albiet in windows NT machines) here at work and have had nothing but good experiences with them. I love the 3com and i have a hard time using anything else (execpt if it is free of course :-> )

Physical Security Trumps Insecure Software (2)

Christopher B. Brown (1267) | more than 14 years ago | (#1438430)

... If the box is sitting in a concrete bunker, with no wires heading to the outside world, and armed Rangers around the base, this issue isn't that much of an issue.

I really don't think this is a significant matter for machines that are either:

  • Not required to be particularly secure, or
  • Are housed in rather secure environments.
It's fair to say that AMD might provide "better bang for the buck;" the insecurity of microcode is, however, something that organizations have been coping with since microcode computers were invented, which likely dates back to the '60s.

As for "You'd never know it," a secure US Army site is likely one of the places to which Intel would be willing to release secrets as to protocols necessary to validate that the microcode hasn't been tampered with, no?

If you are going to be looking at sat images and want a card like that you probably want good hw accelerated for a final result. I dont know of any really good OpenGL (assuming thats what you might use) accelerted cards that fully support Opengl.

Use all that money that you would've spent on new hardware and give it to the boys -- they're already underpaid enough as it is. Honestly, the idea that the US Army would use Slashdot for their recommendations is silly. It gives me a pretty good twinge of fear about our national security. Do you really speak for them, and if so, could you please give us your full name?

While there is no question that the American military has been pushed into some questionable situations, it is also true that the world is probably a better place because of their stabilizing influence.

Would you rather there was ethnic cleansing in Kosovo, or perhaps you would have preferred the Iraqi's to overrun Kuwait? And let's not even get started on what would have happened if the Americans hadn't meddled in World War II.

Not too mention the fact that if the US Army did not exist then the United States would almost certainly be invaded. That may not seem like a big deal to you. But hey, I live here.

Perhaps it would strengthen your argument if you listed some of the places that you feel that the US should not be involved right now.

Given the target processor (700+ mhz Intel) you might as well be looking at an Alpha box; overall performance is likely to be much better (assuming the code has been ported over) the alpha box will let you get away with significantly more cache and memory then its intel counterpart and in this power bracket the price range is similar.

You dont have to agree with the killing people part, but not everyone in the Army is involved in offensive capabilities. They do a lot of basic research, and do a lot of defensive things to allow you to express the opinion you just expressed. The Army employs scores of people who have never shot an enemy or been deployed in a forward area to get rid of an enemy. The Army is almost directly responsible for the first non-soviet artifical satelite. The millitary has been behind countless technical innovations that make your life the way it is, RADAR, plastics, commerical aviation, the Internet etc. Their business is to protect Americans and to protect the American way of life. That does including killing people but it also includes engaging in research to use technology to their advantage, the fruits of which are all around us today.
