Now things went even worse. I assume that numpy built with BLAS and LAPACK should do dot operation faster than "clean" installation on relatively large matirces (say 2000 x 2000). Here I don't use OpenBLAS anyway.
No, _dotblas is only built against ATLAS, MKL or Apple's accelerate framework. So with OpenBLAS you have to call e.g. DGEMM from OpenBLAS yourself instead of using np.dot.
So how can I fix this? Many thanks in advance.
You might fix NumPy to build _dotblas against OpenBLAS as well :) Sturla
