Approximately same thing on 2*xQuadCore HP. I use 4 threads only. No big difference with V25, but, if You like faster check - you can just test 2 exponents with 2 threads each (yes, a bit throughput loss, but just a bit, i have 0.030-0.031s for "single thread" and 0.016s for two-treaded check) \____Cat /\ /\ -- _______________________________________________ Prime mailing list Prime@hogranch.com http://hogranch.com/mailman/listinfo/prime
