Dear Freddie, I managed to build and link the ATLAS library. I've run some tests but it gives me lower performance than I expected: OpenBLAS (single-threaded) outperforms ATLAS by 20-30%.
I know that the peformance of BLAS is platform-dependent and that your good experience with ATLAS is not directly extrapolated to my case. However I'd still like to give it a chance. As you very well indicated, a good performance on the BLAS library used is essential. Would it be possible to have a reference of the times per iteration using PyFR and different BLAS libraries, single proc, for a given case you run in the past? Perhaps you have this information reported at some moment in the past? On the other hand, Would it be possible for you to provide with the compiled ATLAS library *.so? I could test it myself, of course as long as we're using similar LINUX OS. Many thanks in advance.
