Re: [Numpy-discussion] dynamically choosing atlas libraries

Hi, Not a developer here, but I was under the impression that you can only use the BLAS/LAPACK libraries that where chosen at build time? As a side note: I've read [1] that OpenBLAS on some systems could perform quite well compared to ATLAS, I used some simple benchmarks [2] and noticed that on m

2013-04-05 Thread Edward Walter
Hello List, We're standing up a new computational cluster and going through the steps of building Numpy etc. We would like to be able to install multiple versions of ATLAS (with different build settings / tunings / etc) and have Numpy load the shared Atlas libraries dynamically based on the L
