Ok, here just a few numbers. System: 52.000 atoms, coarse-grained, 500.000 steps
BlueGene/P: 16(procs) x 4(threads) = 64 tasks (or whatever they are called) 8x4 7.25 h 16x4 11 h 32x4 > 12 h (queue only allows <= 12 h) BlueGene/L: 16x2 10 h 64x2 > 12 h Note: the procs x threads figures above are the numbers I asked for. It may be possible that the scheduler distributes in a different manner. I don't now. That's all I have for the moment. On Mon, 2008-03-31 at 17:29 -0700, Peter Tieleman wrote: > Thanks.
