Thanks to you all for your testing. Everything seems to be successful - I'll try to release 0.14 next week.

The lag can be reduced a bit by lowering the GPUSieveSize. Your Linux Catalyst version also seems to be much lower (938.2) than your win version (1124.2) - and they are all quite old, Catalyst 13.12 has version 1348.5. Anyway it is good to know that mfakto 0.14 also works with older drivers.

Did anyone (besides me) run the selftest with the LessClasses mode (MoreClasses=0)?

On it on GCN :smile:

st2 with lessclasses, 287351 tests passed :smile:

mfakto 0.14 available
 

I have released [URL="http://mersenneforum.org/mfakto/mfakto-0.14/"]mfakto 0.14.[/URL]

As most people seem to use the GPU sieve, I no longer created the versions with different (CPU-) sieve sizes. If anyone still needs them, just let me know.

Thanks to all testers!

Here again what's new:
[LIST][*]--perftest enhancements including GPU sieve evaluation (for optimizing GPUSievePrimes etc.)[*]successfully resync when the working directory was temporarily lost (ejected USB device or interrupted network drive)[*]save and reload compiled OpenCL kernels => reduce startup time (UseBinfile config variable)[*]MoreClasses config variable to allow for a "less classes" version for very short assignments (GPU sieve only)[*]BugFix: enforce GPUSieveSize being a multiple of GPUSieveProcessSize[*]FlushInterval config variable to fine tune the number of kernels in the GPU queue => address high CPU load issue of newer AMD drivers[*]MinGW build (thanks to kracker)[*]slight performance improvement for the montgomery kernels[*]improved English wording in program output, ini file etc. (thanks to kracker)[*]recognition of new GPUs (8xxx, R9, new APUs) (thanks to kracker)[*]added a warning when using VectorSize=1 (AMD driver issue (?), [URL]http://devgurus.amd.com/thread/167571[/URL])[*]fix for a small memory leak (~0.5kB per assignment)[*]works on Win8.1[/LIST]

I guess my OS is too old :razz:

I don't like it:
[LIST][*]there is no double speed improvement[*]there is no triple speed improvement[*]it can not play minesweeper! (thanks to kracker)...[/LIST]
:razz:

Is there any practical difference in the results from the pre4 version to the release? I discovered that I left the pre4 version running assignments for a couple of days. If needed I'll just rerun them but I rather run new assignments if I can. :smile:

No, the different version string is the biggest difference :smile:
No need to rerun anything.

Oops, I did not notice this new requirement when I switched to gcc 4.9 :shock: Can you install the 4.9 version or should I try to build on older gcc for you? :boxer:
I need to update the requirements section ...

Don't worry, I built it myself again :smile:
