I've been exploring this further here - http://www.gamedev.net/community/forums/topic.asp?topic_id=585405 Also, from what I can tell, MPI messages are composed of one data type or an array of one type. If that's the case, I'd argue there's room for more coolness. Brian Wood Ebenezer Enterprises http://webEbenezer.net

Maybe, but the library lets you easily make arbitrarily complex data types (described to MPI as MPI type maps).
If that's the case, I'd argue there's room for more coolness.

That is absolutely not true. The fact that you might think so is just a sign of how hard it is to understand how to send messages of more complex data types. This is where Boost.MPI comes in and makes it easy. Matthias
