Well said.<BR>

Grumpy MPI. Now there's a name for a new open source project, if I have ever seen one.<BR>
<BR>
Let's start it now - a new MPI implementation which is intended for clouds and geographically<BR>
separated machines with high latencies between them. The MPI implementation will cope with <BR>
Network interruptions of a long duration, but will of course produce copious grumpy error messages.<BR>
<BR>
And we can have mailing lists which are famed across the Internet for their spikiness and flame wars.<BR>
I vote we invite Victor Meldrew to be the project's new figurehead.<BR>
