We run a script on each node that uses the ipmitool command to pull

That's either 4x32 bits single precision or 2 x 64 bits double

Ok easy theoretic calculation, and it's still very rude of course:
1 core 2.4Ghz * 3 instructions a cycle * (sse)2 = 7.2 * 2 = 14.4 Gflop
4 cores of a quad core ==> 57.6 gflop
3 nodes ==> 3 * 57.6 = 172.8 gflop
Now of course your software won't be able to get that out of the
hardware at core2
Vincent,
I'm missing something in the arithmetic. "3 nodes of quadcore" is 12
cores? delivering 100 "GFlops" would require something like 8 GHz? So
perhaps you mean, 3 nodes of dual socket, quadcore CPU (24 cores) at
4GHz? And you can get that for $1500?
Thanks,
Peter

The power draw is a combination of a fixed load plus a frequency dependent
load, so for the SAME processor, running it at N/2 GHz consumes more than 50%
