Now there's a name for a new open source project, if I have ever seen one. Let's start it now - a new MPI implementation which is intended for clouds and geographically separated machines with high latencies between them. The MPI implementation will cope with Network interruptions of a long duration, but will of course produce copious grumpy error messages. And we can have mailing lists which are famed across the Internet for their spikiness and flame wars. I vote we invite Victor Meldrew to be the project's new figurehead. http://en.wikipedia.org/wiki/Victor_Meldrew The contents of this e-mail are confidential and for the exclusive use of the intended recipient.
