I think it is a valid question in the context of a survey about MPI. It
is about the API they're calling. Other environments may choose to use
MPI in the implementation, but that's not part of their specification.
Could be anything.

Please stop perpetuating the myth that MPI and PGAS are opposed by
asking questions that support this false dichotomy.
Lots of folks use MPI via other APIs, whether they be PETSc or Global
Arrays. Thanks to MPI-3 RMA, PGAS can be just another abstraction
layer on top of MPI.

using any other parallel language/library? */
/A PGAS language (UPC, Coarray Fortran, OpenSHMEM, XcalableMP, ...)/
GCC/OpenCoarrays and Intel MPI both use MPI-3 RMA as a/the
communication layer. OSHMPI is very close to a 1:1 mapping between
OpenSHMEM and MPI-3 RMA. UPC could be ported to MPI-3 RMA with
dynamic windows if someone cared.

Hello, MPI Forum members,
I, George Bosilca (UT/ICL) and Emmanuel Jeannot (Inria) are
working on conducting international MPI survey to reveal the
differences among countries and/or regions around the world. I
had a chance to talk on this project at the MPI Forum meeting in
San Jose and many attendees agreed to help our project. You can
find the attached PDF file which was presented at the MPI Forum
meeting.
I would like you to go to the GoogleDoc (Google account is required)
https://docs.google.com/forms/d/e/1FAIpQLSfWLWsuhr4opqvn1FL5c8p7Ysz-oclZEMlBAzEGnBZkaaIiKQ/viewform
to fill in your answers. At the end of the survey, I added some
questions only for MPI forum members so that you can leave your
comments on our survey.
It is designed to be short and easy. I am quite sure you can
answer all questions in 5 minutes. I hope some MPI Forum attendees
can answer the survey at airport while you are waiting for your
flight.
The deadline for MPI forum members is next <<<< Tuesday 11, Dec >>>>.
The survey in production will be conducted in the upcoming January
2019, hopefully. The first draft report will be available to all
of you in April 2019.
