Hi all!

I realized that there is no “whl” files for PPC64 (https://pypi.python.org/pypi/numpy/1.12.0b1), which makes numpy be compiled when installing it with pip. It is causing a low performance on this architecture when the libopenblas is not previously installed, while for x86_64 it is installed as a lib, which is in the “whl” file.

What must to be done to add a build of numpy for PPC64, and upload the “whl” files to pypi link?

The problem for wheel files is agreeing to some standard for binary compatibility that guarantees the wheel will work on more than a single Unix distribution / version. The work to do that for Intel Linux is over at https://www.python.org/dev/peps/pep-0513 . As you can see, that PEP defines a standard set of libraries and library symbol versions to build against, such that the resulting wheel will be compatible with a large number of Intel Linux distributions. There's also a standard docker container to build with, containing the correct libraries / symbols. Otherwise, you'll have to build the wheels for your platform only, and put them up somewhere in a web directory, for others with the same platform. It doesn't make sense to put them on pypi, because, unless you have done the standardization work, they will likely fail for most people. Best, Matthew
