[Numpy-discussion] what do I get if I build with MKL?

Fri Apr 19 10:10:33 CDT 2013

Looks like the *lapack_lite files have internal calls to dgemm.  I alos found this:


So it looks like numpy/scipy performs better with MKL, regardless of how the MKL routines are called (directly, or via a numpy/scipy interface).

For the matrix multiplication or array dot, you use BLAS3 functions as they are more or less the same. For the rest, nothing inside Numpy uses BLAS or LAPACK explicitelly IIRC. You have to do the calls yourself.

And does numpy/scipy just then automatically use them?  When I do a matrix
multiply, for example?
