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.
NUM_CORES=2
I will ask on the OpenBlas mailing list
https://groups.google.com/forum/#!topic/openblas-users/2cxnw0tvd9A
"one of the testers noted that his quad core is unable to use more than
two cores; as the build machine is a two cores, is that causing the
limitation ?
Yes.
There is a mode to override it ?
Use "make NUM_THREADS=n " to support n threads. "
So how many THREADS would you like to see ?
