So how many THREADS would you like to see ?
I think 8 would cover the majority of users, 16 at the most. I've seen
cases where openblas can try to use threads on small problems where it
shouldn't need to, so it would be good to check whether it's smart about
avoiding oversubscription if you run it without setting
OPENBLAS_NUM_THREADS.
I will prepare another package
Of course users who really want more threads can compile it themselves,
but it'll be convenient to have a fast blas easily hooked into Cygwin's
packages for numpy, R, octave, etc.
R uses it own blas+lapack so no improvement on that side.
