<p>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.<br>

<div>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.

<div>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.</div>

members,<br>
<br>
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.<br>
<br>
I would like you to go to the GoogleDoc (Google
account is required)<br>
<br>

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.<br>
<br>
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.<br>
<br>
The deadline for MPI forum members is next
<<<< Tuesday 11, Dec >>>>. <br>
<br>
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.<br>
