OpenCL vs. CUDA for NVIDIA GPGPU
Is it true that CUDA code runs on NVIDIA GPGPU is much more efficient\fast
compared to an OpenCL code (that does the same computations) that runs on the same GPGPU ?
I don't think you can easily compare that. OpenCL code will be compiled to the same binary code as cude on an NVidia GPU. So it should be the same performance when you get your code tweaked correctly. There could be a better performance becaus of an easier integration into your sourcecode (compiletime in cuda vs runtime in openCL)
Thank you for your help !
