Teraflop In A Box At SC2003
HPC Prophet writes "For those of you that can't go to SC2003 or can't afford the US$750 late registration, here is a small taste of what we put together for our friends at Mellanox Technologies...It benches out at over 1.2TFLOP (192 dual Intel Xeon Processor blades, 64 in a Rackable chassis, 128 crammed into a Ciara chassis and all connected via InfiniBand) and loaded up with Callident Rx (based on NPACI Rocks) OS/Middleware. Total estimated time to unpack, build and get up and running was 17 hours." Read on for some details on this power-hog.
"We had the single-most power density for the smallest size booth they offer (380amps @ 208v in a 5U of rack space (look closely at the bottom of the middle rack containing all the cables and InfiniBand switches). Cooling was very nice too, we maxed out our Liebert HVAC when building it initially. Oh, by the way, this would end up somewhere in the neighborhood of #38 on the June 2003 Top500 list. There are a couple of other pictures on there too of some of the other attractions at SC2003 like the 128-node cluster that NPACI folks will build in a 2 hour period. Sorry about the cheezy slide show, I had to be quick."

High performance computing, networking and storage conference
Funny you say that ... MS does daily automated builds of Windows for all it's supported CPU platforms and does installs to a large farm of workstations. For Win2k, the build cluster was comprised of Compaq 8x processor Xeon servers. I imagine they may have moved to larger hardware like a Unisys E7000 by now. Windows is well over 20 million LOC now, and doing a daily build takes over 10 hours.
meh.
SC2003 is Supercomputing 2003. They hold this conference every year around this time.
Unless you're REALLY into supercomputing (and these days, it's mostly cluster stuff), this isn't exactly the most exciting conference you can go to.
Meanwhile, IBM recently built the prototype for a single BlueGene/L node, and it manages to cram 1024 PPC440 processors, with a Rpeak of 2Teraflops, and an Rmax of over 1.4TF into about half the space of the full racks mentioned in this article.
While this article is obviously about a somewhat less custom system than BlueGene/L, I'd have to say I'm much more impressed with IBM's achievement.

First off this system is NOT the 38th most powerful computer; in fact as far as I can tell they (Rackable) aren't even on the current top500.org list. Oh, too bad couldn't get linpack to run?
/. it is obvious he is the so-called HPC Prophet. Take your head out of your ass buddy.
/. of all places. Not to mention Ottero's Callident RX software, that is supposedly running on this cluster, has absolutely no redeeming qualities. The most useless, stale Cluster management software you'll find.
Glenn Oterro is a devious bastard that likes to call himself "{foo} Prophet"; his email sig claims Linux Prophet, on
He is an egotistical ass-clown that likes to promote his yet-another-useless-HPC-poser-company (Callident) to the masses of
