Taking 1051_71_minus1.

Just out of interest, what's the hardware for that? That's a very impressive speed for a non-MPI job ...

I think it is a MPI job.

Greg: great :smile:

Carlos: OK, I'll somehow generate more relations. The yield on the 40M-45M range has been miserable, I seriously think I uploaded the wrong poly: I initially trial sieved with 29-bit LPs, then tried 28-bit LPs with lackluster success, but seem to have forgotten to go back to the 29/58 version and uploaded the 28/56 version...

Until you get this one fixed I have plenty to play around, 698419_37_minus1 and 293_97_minus1 are ready for post-processing. Tomorrow I will start 1051_71_minus1 and it must be a 2 days task.

At a guess, Greg is using 8 quad-cores with infiniband.

Exactly. But these are Core 2 quads with DDR2 memory, and I've found it's faster to use only 2 cores on each rather than all four.

Why? What about only three?

Memory contention. Empirically, two is optimal.

Can you do anything else with the other cores? Perhaps some ECM stage 1?

1051_71_minus1 will de done in less than 16 hours. Next I'll do 698419_37_minus1 and 293_97_minus1.
