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.
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. -Tony -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
