Calling 16 PS3s a supercomputer is a bit of a stretch. The article doesnt quote any numbers either. Cell with 8 SPEs can do about 200 Gflops SP matrix multiply.

Calling 16 PS3s a supercomputer is a bit of a stretch. The article doesnt quote any numbers either. Cell with 8 SPEs can do about 200 Gflops SP matrix multiply. So I assume PS3 can do about 150 Gflops. 16*150=2400 gflops single precision .. not a supercomputer by todays standards i would say.
- cstejerean 19y agoCertainly 16 PS3s is no Blue Gene. But perhaps good enough for a lot of problems and hopefully cheaper to build than using standard desktop/server hardware (since you get the PS3 hardware at a discount).
- pmjordan 19y agoIt's still a lot faster than your average physics department's 32-node Xeon cluster.
- comatose_kid 19y agoI'm curious - where did you get that 200 Gflops number from? Is that theoretical, or actual for large values (say 10k) of N?
- randomhack 19y agoThats from a paper called "Potential of Cell processor for scientific computing" .. they quote a figure of 200 gigaflops for single precision GEMM (generalized matrix multiply) for large square matrices (using a simulator?). Assuming their model is very accurate, its actual 200 gflops.
