Need a hint: window / one-sided

[rabauke]

One-sided communication has not yet been implemented. I never had a use case for this.

Understood. I do hope you can find time for it. Judging by commits you are still working on MPL.

I find MPL a very elegant front-end to MPI, and C++ is an increasingly popular language in computational science. I'm working on an MPI (& OpenMP & PETSc) book and I've started incorporating MPL examples and explanations. It would be nice if I could advocate MPL as a complete MPI API in trainings that I do.

Btw, windows are needed for MPI shared memory, and that is definitely a very useful thing.

Nice and useful writeup.

If time permits I will think about how to map MPI windows and one-sided communication API to a nice C++ API. This has, however, not highest priority for me. If one would aim to extend MPL to a feature complete replacement for MPI (what I do not), one would need to implement many other features as well: IO, process creation, etc.

I/O was going to be my next question :-)
