More apps based on v1.4 of wrapper code are now available.

First there are Android apps with both non-PIE (for pre-4.1) and PIE (for 4.1 and later, especially 5) versions. Android apps are no longer in beta so everybody should get them but please report any problems at the new Android forum http://moowrap.net/forum_forum.php?id=27.

Secondly there's a new nVidia OpenCL app available for Windows. This brings the same level of support for nVidia GPUs that was previously available only for AMD GPUs. The Linux versions are on the list next and will be deployed soon.

Happy crunching!

1.04 steals a whole CPU. I now have a paused CPU project because of it. 1.03 did not do this. Can that please be fixed. I know that OpenCL usually is better about CPU need than CUDA, but the CUDA app doesn't steal a CPU. I also leave cores open for GPU stuff, so I have free cores already.

Right, it was reported to me previously that the OpenCL (especially nVidia one) benefits from having one free CPU for it to feed the GPU and thus is specified as requiring one CPU. However, this does change a lot between Windows and Linux as well different driver versions so it's not that easy to find "correct value".

I can surely change it, that's not a problem. I'll make it same as AMD OpenCL app (it requires 0.25 CPU) for now to see how things go. The change should be live within an hour and subsequent work sent should have the changed CPU requirement.

Thanks for the report!

Perfect! The timing of completion has not changed and the units are validating nicely. Thank you for making that adjustment. It is appreciated.

So the fast card uses Cuda which is slower than OpenCL. I could be doing nearly twice as much work but there are no options to allow me to pick this as the requested app. It has run the OpenCL app a few times, but keeps reverting back. This host's results are the one in question. If you look through complete work, there are a few 1.04 scattered throughout.

Thank you.

Will this include support for 7950 GPUs?

Thanks

Looking through the latest results, it's mostly running the OpenCL app now. It can take a while for the BOINC scheduler to start preferring the faster app and it might once in a while test run the other one to see if things have changed. Hopefully things keep going this way for your host.

Ah, yes, the new OpenCL app should run on those. Linux apps are now in beta so if you want to give them a spin before I release them for all you can opt in for beta work. Thank you for any tests done (or your patience if you just wanna wait)! :)

Good news!!

... except that there's no preference setting for beta work as there is on other projects.

That's because they are no longer beta and are available for all. And when there are no beta apps, the beta setting is automatically hidden.
