Hi all,
I develop at the moment with new HD 7950 and I try the new 12.2 pre-certified driver now 12.3. My application is multiple context with multiple threads style and until now it worked all the time without problems. With the new driver it chrashed with a blue screen if I release the complete stuff with a call like that:
parallel_for(0,static_cast<int>(pOpenClDevices.size()),[&](int l)
{
clReleaseKernel(pOpenClDevices.OpenCLBackPro);
clReleaseKernel(pOpenClDevices.OpenCLBackPro2);
clReleaseKernel(pOpenClDevices.OpenCLResetImage);
clReleaseKernel(pOpenClDevices.OpenCLReset);
clReleaseKernel(pOpenClDevices.OpenCLScaling);
clReleaseContext(pOpenClDevices.Context);
});
I use lambdas in combination with the PPL from Microsoft VS 2010. This just an example it sometimes also crashes during a parallel read back. Have any else that multi threading problem is there a workaround. Single threading is no solution it works but for HPC issues with up to 8 GPUs per machine the increasing of calculation time is to big. It runs also with one device without errors or with an older driver.
Thanks in advance
