Proposal - change to OpenBLAS for Windows wheels
Hi, I suggest we switch from ATLAS to OpenBLAS for our Windows wheels: * OpenBLAS is much faster, at least when Tony Kelman tested it last year [1]; * We now have an automated Appveyor build for OpenBLAS [2, 3]; * Tests are passing with 32-bit and 64-bit wheels [4]; * The next Scipy release will have OpenBLAS wheels; Any objections / questions / alternatives? Cheers, Matthew [1] https://github.com/numpy/numpy/issues/5479#issuecomment-185033668 [2] https://github.com/matthew-brett/build-openblas [3] https://ci.appveyor.com/project/matthew-brett/build-openblas [4] https://ci.appveyor.com/project/matthew-brett/numpy-wheels/build/1.0.50
Makes sense to me.
