[Numpy-discussion] Using OpenBLAS for manylinux wheels

2016-03-28 Thread Matthew Brett
Hi, Olivier Grisel and I are working on building and testing manylinux wheels for numpy and scipy. We first thought that we should use ATLAS BLAS, but Olivier found that my build of these could be very slow [1]. I set up a testing grid [2] which found test errors for numpy and scipy using ATLAS

[Numpy-discussion] numpy in python callback from threaded c++

2016-03-28 Thread Burlen Loring
Hi All, in my c++ code I've added Python binding via swig. one scenario is to pass a python function to do some computational work. the Python program runs in serial in the main thread but work is handled by a thread pool, the callback is invoked from another thread on unique data. Before a
