PyAF Powerpc support (IBM S822xx) #160

Closed antoinecarme closed 3 years ago

antoinecarme commented 3 years ago

Someone asked for PyAF powerpc support (IBM S822xx). This can be seen as a software robustness/portability test for PyAF.

Need to run all PyAF tests on a Debian Linux PPC64 on at least IBM Power8 CPU.

  1. Check that all needed data packages are available (point missing packages).
  2. Run build tests (make -f tests/Makefilebuild-tests), travis-ci equivalent
  3. Run extended tests (make -f tests/Makefile all)
  4. Analyze numerical differences if any.
  5. Big Endian / Little Endian ?

The hardware is made available through the excellent Minicloud, The FREE OpenPower Cloud by Unicamp , Campinas, Sao Paulo, Brazil

Big Thank you, @Unicamp-OpenPower !!!

Keras package is available, but not usable as tensorflow does not support powerpc platform.

Better use PyTorch !!!

antoinecarme commented 3 years ago
  1. Run build tests (make -f tests/Makefilebuild-tests), travis-ci equivalent

Perfect !!!

antoinecarme commented 3 years ago

A few very small numerical differences , this is normal. The reference numbers (_ORIG) come from an x86 platform run.
