You mean because of the default CPU affinity stuff in the default OpenBLAS? If we ship OpenBLAS with a windows binary of numpy / scipy we can compile OpenBLAS with the NO_AFFINITY=1 flag to avoid the issue. -- Olivier http://twitter.com/ogrisel - http://github.com/ogrisel _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
