Re: [Numpy-discussion] Building numpy with ATLAS

As it turns out, I just had to run "python setup.py build --force" after changing my site.cfg file in order to recompile numpy/core/multiarray.so. ___ NumPy-Discussion mailing list NumPy-Discussion@scipy.org https://mail.scipy.org/mailman/listinfo/numpy-

[Numpy-discussion] Building numpy with ATLAS

Hey Everyone, I am trying to build numpy-1.11.1 with ATLAS libraries. The build completes successfully, and I am able to use numpy, but there seems to be some problem with my config because numpy only ever uses one core, even when multiplying 5000x5000 matrices with numpy.dot. My site.cfg is

Re: [Numpy-discussion] building numpy with atlas on ubuntu edgy

I'm having great difficulty building numpy on solaris with the sun compilers and libsunperf. I may try this on ubuntu x86_64 to see if the setup is less painful. Thanks for the idea, -Peter On Wed, Apr 18, 2007 at 11:04:26PM +0200, Christian Marquardt wrote: > Sun has recently released their com

Re: [Numpy-discussion] building numpy with atlas on ubuntu edgy

Sun has recently released their compilers under an opensource license for Linux as well (Sun Studio Express or something), including their perflib - which includes Blas and Lapack. Has somebody tried how that combination performs, compared to Intel MKL or Atlas? I think they are free even for comme
