My PC has GPU only selected, it keeps asking for new tasks but server keeps saying there are CPU tasks but says my Prefs will not accept them....I know that! Why are there no GPU tasks?

With the new server I updated the scheduler to correctly check for the OpenCL double extension rather than just checking the hardware; however only the most recent (and possibly unreleased) clients send back the supported OpenCL extension, so almost no Nvidia/OpenCL tasks are being sent out. I'll fix it soon.

That would be great. I had two PCs crunching, one with ATI, one with NVIDIA, on the GPU, but since the move of server......nothing!

I'm running BOINC 7.0.2 (latest version), and my GPU is double-precision capable, but the server reports: "GPU lacks necessary double precision extension"...

Well, fwiw, I seem to get GPU task VERY sporadically, and when it does, it's usually only one (70 second) task. Came in to find it with no GPU tasks at all this morning...
