			MPI Poll '95 Results

A poll was conducted 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.

The complete results of the poll are also available on WWW at the
following URL:
