Student and Professor Build Budget Supercomputer

@ 2007/08/31

This past winter Calvin College professor Joel Adams and then Calvin senior Tim Brom built Microwulf, a portable supercomputer with 26.25 gigaflops peak performance, that cost less than $2,500 to construct, becoming the most cost-efficient supercomputer anywhere that Adams knows of. "It's small enough to check on an airplane or fit next to a desk," said Brom. Instead of a bunch of researchers having to share a single Beowulf cluster supercomputer, now each researcher can have their own.

As stated in their article, the linchpin to having a Beowulf cluster is having equal parts bandwidth per core per RAM. They did 2-core+2Gb+2Gbit ethernet for each of the 4 "clusters".

Now imagine what 4-core, 4GB, 4Gbit ethernet per cluster would cost... Q6600 is not a viable option without major costs in networking hardware.

Interesting that they did not choose dual 1Gbit boards over buying 1GBit Ethernet cards though, would have saved some cash there.

Edit: Cost of their exact Beowulf cluster costs $1,281 today, with a DDR2-800Mhz mem upgrade at that. Didn't mess with the networking but total cost could probably be dropped further to about the $1,000 mark.

they still had 165 $ in their table and the CPUs weren't the biggest cost factor

"little added cost" hmmm.. not quite "little".

3800+ X2 : €59
Q6600: €249

100 Core cluster system 3800+ based: €2950
100 Core cluster system Q6600 based: €6225

... you can have 200 Core 3800+ cluster for the price of the Q6600 100 one

not sure if it will be faster, but the goal was "budget", Q6600 is not

Comment from Rutar @ 2007/09/03

so, essentially you could double the power easily for a little added cost, now that the CPUs are so cheap

For our CPUs, we chose AMD Athlon 64 X2 3800 AM2+ CPUs

Imagine a Beowulf cluster of these!
