fair enough. i try to stay in touch with the eigen and nalgebra developers so i have a good idea on how to write code efficiently with them. for openblas and mkl i've been trying recently to call into the lapack api (benches doing that are still unpublished at the moment), that way im using a universal interface for that kinda stuff. and of course i do check the cpu utilization to make sure that all threads are spinning for multithreaded benchmarks, and occasionally check the assembly of the hot loops to make sure that the libraries were built properly and are dispatching to the right code. (avx2, avx512, etc) so overall i try to take it seriously and i'll give credit where credit is due when it turns out another library is faster |
