Q&A¶
-
Do I get it right that perftool can actually point/suggest me the code which will improve /benefit from GPUs?
Answer: Not quite. Performance analysis is a pre-requisite for any optimization work. If the code spends a lot of time in MPI or I/O then concentrate on that. If you can identify areas of the code where computation is significant then think about taking those to the GPU.
