Supercomputer Season: Itanium

[Yousuf Khan]

Yet another supercomputer/supercluster announcement. This time it's Intel
making a supercomputer of Itaniums at Lawrence Livermore, dubbed "Thunder".
I assume that's a dig in reference to Opteron based supercomputer at Los
Alamos named "Lightening".

http://www.intel.com/pressroom/archive/releases/20031116corp.htm

-20 Tflop/s
-960 nodes * 4 CPU/node = 3840 CPU
-8GB RAM/node
-73GB Disk/node
-nodes connected through Intel's Gigabit Ethernet
-Linux OS.

Sorry, I keep seeing this all over the place and I can't resist this
anymore...

Why would "Thunder" be a dig at "Lightening", I thought "Darkening"
would be a more appropriate dig... :PpPPp

hehehe, sorry! :PpP

If you need basic to med complexity webpages at affordable rates, email me :)
Standard HTML, SHTML, MySQL + PHP or ASP, Javascript.
If you really want, FrontPage & DreamWeaver too.
But keep in mind you pay extra bandwidth for their bloated code

More precisely an Intel® PRO/1000 MT Dual Port Server Adapter,
although the press-release doesn't make it clear that there will be
just one.

As John "Dr. Bandwidth" McAlpin hammered me over the head with, the
Linpack test that is used for these Top500 rankings is not bandwidth
intensive. That's why it's so easy to cobble together a bunch of off
the shelf Itanium server boards with off the shelf server cards and
get a high ranking. No need to know or to engineer much of anything,
the way the RedStorm engineers did. This is part of a very unhappy
trend.

What the f%$*??!?! Gigabit ethernet and they're calling it a
"supercomputer"?! Geez, they better stick to nothing but the
"embarrassingly parallel" tasks on this one! With "Lightning" they at
least went for Myrinet, while the smaller "Orange" cluster of Opterons
went for Infiniband. Gigabit ethernet is going to absolutely kill
their performance if they need any measurable quantity of remote data!

Somebody somewhere doesn't know how to spell. The only one who spells it
as lightening I've found, on a quick search, is www.eweek.com. Obviously
for the correct(?) spelling, thunder succeeds lightning.

Robert G. Brown, the guru of the beowulf community, has himself (and I
would imagine a good part of the community) convinced that
interconnect bandwidth doesn't matter much (as indeed it doesn't for
the Linpack benchmark used for Top 500 rankings)

http://www.beowulf.org/pipermail/beowulf/2003-November/008549.html

Needless to say, the people who have labored long and hard to provide
high-bandwidth, low-latency interconnects have a different point of
view, as I tried to point out in reply

http://www.beowulf.org/pipermail/beowulf/2003-November/008553.html

Mr. Brown did not reply. If you want to skip the Beowulf interplay,
you can go directly to

http://www.lanl.gov/orgs/ccn/salishan2003/pdf/camp.pdf

particularly slide 25 et. seq.

The people throwing together these piles of boxes to get Top 500
rankings are perpetrating a fraud and performing a great disservice to
high performance computing.

I am absolutely convinced these last bunch of announcements are publicity
stunts to get themselves on the Top-500 list. This one, the Big Mac, the IBM
Slanted TV set, etc.

Hmm. I'd have said that since sound is slower than light, then it
follows that thunder follows lightning. This would have undoubtedly sent
the Intel marketing droids a-scurrying. Intel follows AMD? Bah, never!

Maybe it's only intended to make a lot of noise? ;)

One could also think about the crash of thunder. (or boom, but crash
fits the metaphor better)
