openblas is written in C
More assembly than C according to github's count. I'm used to building
the full version of openblas including their optimized implementations
of lapack routines, which bring in libgfortran. So nevermind.
I avoided to include lapack as for compatibility
I will need to split exactly as netlib in
something for the future.
USE_THREAD=1 and USE_OPENMP=1, can be used dynamically ;
if I am not wrong.
What does your Makefile.conf say for NUM_CORES? I can't seem to get a
test program with your build to use more than 2 cores (I have 4 + HT)
by setting the OPENBLAS_NUM_THREADS environment variable.
I will ask on the OpenBlas mailing list
