Great article. mpi4py is the ideal solution presented, but I am wondering how hard the error tracking will be on Python since MPICH2 doesn't help much natively.

- yingw787 7y agoHey thanks for commenting! Yeah I think with CPU bound work a lot of the popular effective Python libraries are going to be mostly C-based with Python bindings. I’m not sure how error handling between Python and C currently is but for Python and Java it is difficult to capture even logs thrown from one side to the other for various reasons. I was reviewing gevent (greenlets plus event loop) but that didn’t make it into the post, I’ll take another look at mpi4py!
