Prime95 version 29.6/29.7/29.8

Yes, it does support SSE2. It is a Q8400S (Yorkfield).

Even if it didn't there's a problem, because the default answer is 8192. But unless you simply accept the default, it won't accept 8192.

Weird. Tried it here and I get a default of 32768.

Does the output (especially feature set) look right in Options/CPU?

It is the executable only. The Clang tool chain forced a dependency on OS 10.9.

Thanks for responding.



I couldn't get the executable to work. But since there is a good reason why the command-line tool won't be updated, I might as well change to the GUI.

I did test it - it can work.

Perhaps mprime cannot find the HWLOC library on your machine. HWLOC library is included in the GUI version - try copying it to the folder containing the new mprime. If you can get it to work there is no reason not to use it (other than I don't update it frequently).

Yes, as far as I can tell:

CPU Information:
Intel(R) Core(TM)2 Quad CPU  Q8400 @ 2.66Ghz
CPU speed: 2666.61 Mhz, 4 cores
CPU features: Prefetch, SSE, SSE2, SSE4
L1 cache size: 3x32 KB, L2 cache size: 2x2 MB

I tried 64-bit mprime running on 64-bit linux. The default is still 8192, but now I am allowed to enter any number between 4 and 32768 for the Max FFT size.

The problem seems to be only when running 32-bit linux, because if I run 32-bit mprime on 64-bit linux, the program behaves as expected.

The CPU information shown above is the same for both 32-bit and 64-bit linux.

EDIT: I can't get 32-bit mprime to run under 64-bit linux, so scratch that info.

What this mean?

What steps did you follow to activate the executable? Normally "./mprime" activates it, but not this time. Is there some setup I should do first?

V298b6 does not appear to open and run on Mac OS 10.15.1.

Do you need to do a chmod u+x mprime? Or change the execution permission for mprime on your Mac?

Was it running previously and you upgraded the OS? Or is this a fresh install on 10.15?

If a fresh install can you try moving the hwloc dynamic link library to /usr/local/lib

I got it to work. Thanks!
