It's just four motherboards sitting in a single frame. connected by an ethernet switch.
True supercomputing machines (sun, ibm) have a little bit better interconnectivity between the components than a mere 1Gb/s line. This can serve its purpose though, VASP will run wonderfully on it. GAMESS probably as well.
Anyone know if there has been a top500-compatible measurement of a PS3?
If PS3 costs about $500, one could build a "ps3wulf" with four nodes and some network equipment for $2500. Anyone have any idea how it could compare with the Microwulf?
Sorry for replying to myself, but I found an interesting paper [netlib.org] about the subject. Seems that a PS3 should have Rpeak of 14 Gflop/s with double precision floating point operations. Sounds to me that with a proper clustering solution a four-node PS3 cluster would be significantly faster than Microwulf. And it would probably be a smaller, too:)
You're right, but you're wrong. 14 Gflop/s with double precission using the double precission opcodes, you're right. However, using single precission opcodes to perform double precission computations, you achieve 100 double precission GFLOPS (about the half of the 200 GFLOPS that in single precission mode):

Jack Dongarra and his team demonstrated a 3.2 GHz Cell with 8 SPEs delivering a performance equal to 100 GFLOPS on an average double precision Linpack 4096x4096 matrix. [wikipedia.org]
