Open MPI

Title: Open MPI Developer's Workshop

Author(s):

Abstract:

This week-long, hands-on workshop is being taught by the Open MPI core development team. The goal is to enable 3rd party developers to extend and enhance the Open MPI code base, such as hardware-specific functionality for particular networks or platforms. A detailed analysis of how Open MPI works will be presented -- to include significant time spent examining and discussing the code of Open MPI itself.

Presented: April 17-20, 2006, Cisco Systems Campus, San Jose, CA, USA.

Please note: These slides are only a portion of the data presented at the workshop. There were many "dive into the code" reviews, interactive discussions, and direct/indirect questions asked by the audience.
