A Narrative of PyOpenCL Examples
Dear Ben,
Nice examples, thanks for writing this!
The 030_timing.py
code is doing an unfair comparison of the speed of a slow python loop versus a compiled C-OpenCL code. In this case, the C-kernel will always be faster. A more fair comparison would be to compare the speed of a C-code that performs the sum vs the OpenCL version executed on the GPU. Does this make sense?
Thank you so much for your contribution related to pyOpenCL. Helps a lot. I tried your example
https://github.com/benshope/PyOpenCL-Tutorial/blob/master/021_array_sum.py
but the variables seem to have been swapped on line 39?
cl.enqueue_copy(queue, cl_arrays[x], np_arrays[x])
should probably read:
cl.enqueue_copy(queue, np_arrays[x], cl_arrays[x])
Best regards
Olle
