BTW, I would also like to discuss here, as part of this proposal,
which backend should be the system-wide default. I believe we all
would agree that OpenBLAS nowadays is the best choice. But then, the
serial or the openmp version?
First, I want to make sure I understand the current openblas
packaging. Is this correct?
openblas-openmp: use if the application uses OpenMP
openblas-serial: use if the application is multithreaded
openblas-threads: use if the application is single-threaded
I've always found the naming of the openblas packages to be confusing,
so that may not be right. Somebody set me straight if so.
The question of the default is a hard one. What happens if a
multithreaded application that does not use OpenMP is linked with the
OpenMP build of OpenBLAS?
