			MPI Poll '95

Dear MPI user:

We are conducting this poll to better understand how programmers are
using the rich MPI functionality, what extensions are needed, and
how to prioritize our work to better serve MPI users, and the HPC 
community at large.

We appreciate you taking a moment of your time to answer these few
questions.  Your feedback is very helpful and important.  Feel free
to include your comments at the end of the form.  The results of the
poll will be made public, as well as an anonymous summary of the
comments.

This poll is also available on WWW at the following URL:

Thank you for your help.
