OpenCL and multithread about 64core CPU in windows.

[achinastone]

I try enable OpenCL and HASTHREADS. (in Delphi)

I found clCreateContext will be called repeatedly. After reaching a certain number of times, this function will fail.I checked the information, and it seems that many graphics cards can only create a limited number of contexts. If each thread creates one, for example, 64, that seems too many.

If you are thriving for price/performance, try this:

• As many CPUs as you can without GPU.
• AVX256 or AVX512.
• Large batch size.
• Adam optimizer.

If you are in a MT environment, restrain the max number of cpus to the number of real cores with NeuralFit.MaxThreadNum:= number_of_real_cores;.

Thanks, i will have a try.
