<div class="">Thanks for this good list of unofficial bindings and projects using MPI or MPI-like interfaces.</div>

<div class="">The short answer to your question is: yes, there is an effort underway to provide better support for other programming languages.</div>
<div class=""><br class="">
</div>
<div class="">Some work was done for the MPI-4.0 release of MPI (due this year) to firm up some of the key semantic terms, which will aid us when attempting to express those semantics in new languages. That work is continuing and more results from that are
targeted at the upcoming MPI-4.1 and future versions of MPI. Figuring out the dividing line between what is currently being expressed (semantics) and what is dictated by the current mechanism of expression (C or Fortran) is a first step towards new forms of
expression.</div>
<div class=""><br class="">
</div>
<div class="">Beyond that work, additional language expertise will be needed from some folks who are regular users of these other programming languages so that appropriate expressions of the essential MPI semantics are chosen — language mechanisms that “fit”
with the normal/natural ways that a typical programmer would recognise. One possible strategy that has been discussed is to split the MPI Standard into a single MPI Core Standard and multiple MPI Bindings for <language> Standards. This might happen as early
as MPI-5.0 (perhaps 5-10 years away) depending on how controversial it turns out to be and the rate of progress, which will depend heavily on the amount of interest and sustained contribution from a community of users.<br class="">

It is also used as a possible backend for among other PGAS languages XcalableMP -

Some people did not expect MPI to be used by many developers directly. Are there any thoughts on how better support for other programming languages and MPI as a backend might be improved in future?<br class="">
