<p class=MsoNormal>Jeff, are you aware that we started that table on the wiki
pages? (or you just prefer it in excel?)<br>
<a href="http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Compare_mpi_h">http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Compare_mpi_h</a><br>
<br>
On that same page you can also find the various mpi.h files.<br>

Thanks,<br>

<br>
Just talked to our phone folks. Our trunks are down in New Mexico -<br>
so this is a bust. We are sort of a third world country out here.<br>
<br>
I don't think we have time to reschedule at this point.<br>
<br>
So ... if folks have the time please populate the matrix with your<br>
favorite MPI implementation and distribute to the group. We'll get<br>
into the guts of all this at the meeting.<br>
<br>
For my 5 minute briefing, I'll just show folks where we are and give<br>
a glimpse into the details.<br>
<br>
see you all at the meeting<br>
<br>
