Public bug reported:
First of all, the option to easyily compile a multithreaded atlas is just great!
However, I compared atlas to the OpenBLAS library and recognized it to be
approx. 30% slower. When examining the CPU-load during calculation, I saw atlas
only using 70% of the CPU horsepower (while OpenBlas uses full 100%) and
wondered, if there was an option during compiling that can trigger atlas to
gain full speed.
I attached a screenshot of the CPU monitoring.
Thank you in advance
Stefan
