Linux Clusters Finally Break the TeraFLOP barrier

michael posted more than 11 years ago | from the faster-kernel-compiles dept.

Linux 223

cworley submitted - several times - this well-linked submission about a slightly boring topic - fast computers. "Top500.org has just released its latest list of the world's fastest supercomputers (updated twice yearly). For the first time, Linux Beowulf clusters have joined the teraFLOP club, with six new clusters breaking the teraFLOP barrier. Two Linux clusters now rank in the Top 10: Lawrence Livermore's "MCR" (built by Linux NetworX ) ranks #5 achieving 5.694 teraFLOP/s, and Forecast Systems Laboratory's "Jet" (built by HPTi) ranks #8 reaching 3.337 TeraFLOP/s. Other Linux clusters surpassing the teraFLOP/s barrier include: LSU's "SuperMike" at #17 (from Atipa ), the University at Buffalo at #22 and Sandia National Lab at #32 (both from Dell ), an Itanium cluster for British Petroleum Houston at #42 (from HP ), and Argonne National Labs at #46 (from Linux NetworX ) reached just over the one teraFLOP/s mark with 361 processors. In the previous Top500 list compiled last June, the fastest Intel based Netfinity 1024 processor clusters from IBM were sub-teraFLOP/s and the University of Heidelberg's AMD based "HELICS" cluster (built by Megware ) held the top tux rank at #35 with 825 GFLOP/s."

That shouldn't be too hard... I bet that my Palm Pilot has enough power to predict exactly, what my boss is going to say in the next meeting tomorrow.

If it's about schedules, he'll say:

Work...

  1. harder
  2. smarter
  3. cheaper
  4. faster
In that order.

If it's about project goals, he'll ask me to:

Make...

  1. miracles

If it's about specifications, he'll say: "I have no idea. You find out yourself." And for anything else it would be just blank. All blank.

On the other hand... if a manager actually has any real thoughts... Well, that would be as easy as to predict patterns from a pure chaos.

Have another coffee while it Boots (4, Interesting)

hopbine (618442) | more than 11 years ago | (#4692156)

I have often wondered how long it takes to boot one of these things. In the HP-UX world I know how long it takes for a K class (sometimes more than 20 minutes). Superdomes are sometimes faster, but not by much.

Re:Have another coffee while it Boots (4, Funny)

jelle (14827) | more than 11 years ago | (#4692278)

It's a cluster, so I can imagine the nodes can boot individually, in parallel. Plus I can imagine the system never goes down as a whole, just some nodes may go down when parts break or other maintenance. 1 bootup per lifetime...

Perhaps the boot speed is limited by the ramp-up speed of the local power plant.

Re:Have another coffee while it Boots (2, Funny)

flight666 (30842) | more than 11 years ago | (#4692338)

I had a K570 at a previous job that took literally 45 minutes to boot from power-on to login prompt.

Turning off the extended mem-check reduced this to 25 mins.

I once had a SCSI cable go bad, and I had to boot that darn thing up about a dozen times, swapping out cables, to find the bad cable. What a bad night that was! Swap cable, take 25-min break, watch SCSI errors from kernel. lather, rinse, repeat. 3 hours to find one bent pin on a scsi cable. yuck.

Re:Have another coffee while it Boots (3, Informative)

hopbine (618442) | more than 11 years ago | (#4692479)

Next time this happens, turn the key fully clockwise and on the console do "CTL B". This means it will stop at the BCH prompt - this ONLY works on the K boxes unfortunately, on all others watch the screen for the "hit any key or wait 10 seconds" message. At the BCH prompt type SER. This will do a search of all potentially bootable devices and should include all disc drives. No drive= bad drive, SCSI cable or SCSI controller. By the way, on any HP computer do not disable the memory check unless your troubleshooting, the extra few minutes might save you problems later on.

"Beowulf is an approach to building a supercomputer as a cluster of commodity off-the-shelf personal computers, interconnected with a local area network technology like Ethernet, and running programs written for parallel processing. " (http://searchnetworking.techtarget.com/sDefinitio n/0,,sid7_gci211652,00.html)

This article is about creating supercomuters using Beowulf technology. It isn't about how many CPUs can be put into a single box, but about how you can network many boxes together. This being the way to make inexpensive super computers. My point is, is that you can use MAC hardware beowulfed. My logic was, is if one MAC has the highest amount of FLOPS in one of their PCs, why would a bunch of their PCs not have an even great amount of FLOPS?

I am not a mac guy, but it is just something that comes to mind when you read an article about supercomputers, clustering, and FLOPS.

Last time i checked a dual g4 1.25 ghz system was below that of a p3 3.06+hyperthreading in graphics benchmarks (adobo after effects + photoshop). (the dual g4 system also cost $1k more).

It may still be ahead in gflops... I'm not into cpu's enough to answer that but i do doubt that. In any case mac's are for graphics people so that should be a real blow.

But I'll bet dual 2.4 ghz xeons will kick the 1.25 ghz system's ass in terms of gflops. Plus there only like $650 each so the mobo + processors won't cost more then $1400.

Ah, that would be because Apples 'supercomputer on the desktop' marketing drivel was just that.

Hell, the Sony Playstation 2 was subject to export restrictions because it was 'too powerful', which was driven by/followed with the requisite marketing drivel, but you don't see and PS2 clusters in the 'Worlds fastest supercomputer' list either.

It has been a long time since Apple PPC was competitive in terms of price/performance with x86s. Of course thats not the only reason to buy a computer, i don't want to get the apple-zealots panties in a bunch.

It's just that Intel/AMD didn't make a song and dance about breaking the GFLOP barrier, since that happened way back with the P3/Athlon 600-800, hardly cutting edge chips.

Hell, a 600Mhz Alpha had GFLOP performance years before either the G4 or the x86s.

The PPC has a nice vector processing unit (Altivec), which could make it a good choice in some situations, but given the premium you pay for Beowulf nodes (Xserves?) from Apple, you will, in general, get a lot more bang for the buck from x86.

Beowulf clusters aren't so tricky... (5, Interesting)

caluml (551744) | more than 11 years ago | (#4692186)

I built a small Beowulf cluster. It was actually very easy, apart from writing the MPI enabled code.

Step 1: Install the lam packages on all the nodes
Step 2: Create an account on all nodes, and use a passphrase-less ssh key to avoid prompting.
Step 3: Compile your code with mpicc (rather than gcc)
Step 4: Copy to all nodes.
Step 5: mpirun C ./your-prog

Admittedly it was only a 4 node cluster, but hey ;)

Please, someone break it to me gently if this wasn't actually a Beowulf cluster ;))

I have some students from Boeing that are just in love with Linux. The Engineer department there just set up a Linux Cluster with 120 nodes for around 100,000 US dollars. They were running tests on it and found it was much faster than the Cray they had previously been using to do the same things.

The main comment that struck me was how easy it was to set up. The Engineer IT department is mostly Unix (they're all in retraining becuase they are dumping Sun Stations for Intel based systems running XP beleive it or not- becuase Intel chips are so much faster and machines running XP are much cheaper than Sun Sparcs (plus the software they want runs on XP)) so it was of course easy to set up for them.

Next they'll be setting up another LINUX cluster with maxed out dual or quad processor machines with more RAM. They're really excited.

Impressive numbers (3, Informative)

While most people seem to be complaining about the number of links in the story, if history is any indicator, 90% of people won't click on one of those links, let alone all of them.
