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. ID: 52261 · Rating: 0 · rate: / Reply Quote

I had two PCs crunching, one with ATI, one with NVIDIA, on the GPU, but since the move of server......nothing! ID: 52262 · Rating: 0 · rate: / Reply Quote
