Wprime

[ncc-1709]

ok, this is a strange and iritating one for me.

when i run Wprime, thread3 is allways 0.3 seconds per loop slower than any other thread, so on 32m, its 1.2seconds slower than the rest to finish. on 1024m, its 30 seconds slower. is this normal or is there something worng with my os which is causing it, because i should be beating some times, but this bug keep ruining my times.
many thanx

Happens to me as well

If it happens to anyone there's no problem... or at least it's not unfair. ; )

ok, that makes me feel a bit better about it.

If it's on a hyperthreaded machine, this is to be expected, to compensate, increase the number of threads to 5 for a single core, 2 thread chip, or 10 for a dual core 4 thread chip.

If it's on a multithreaded system with sync'd clockrates for each core, then wPrime didn't sync it's threads properly, press ~, type initthread <enter>, then type gui <enter> and try again.

In fact, this might be an explanation for the difference in speed between different versions. Will post some results shortly.

Standard Sync: http://wprime.net/score.cgi?id=14532 (CPU @ 2.8GHz)
Sync 2: http://wprime.net/score.cgi?id=14533 (no change...:confused:)
Sync 4: http://wprime.net/score.cgi?id=14534 (ok its not that)

Threads were in sync already though (even in the standard syncing). Maybe the single syncing isn't enough for quad threaded systems, but its enough for my little dual threaded box. Anyways, try the above, if its a sync problem then that should fix it.

just where do you type it?
and itsa only happening on quadcores

Press ~ for the console.
