Abstract: MPICH is a widely used, open­ source implementation of the MPI message passing standard. It has been ported to many platforms and used by several vendors and research groups as the basis for their own MPI implementations. This BoF session will provide a forum for users of MPICH as well as developers of MPI implementations derived from MPICH to discuss experiences and issues in using and porting MPICH. Future plans for MPICH will be discussed. Representatives from MPICH­-derived implementations will provide brief updates on the status of their efforts. MPICH developers will also be present for an open forum discussion.

Long Description: MPICH is a widely used, open­-source implementation of the MPI message passing standard. It has been ported to many platforms and used by several vendors and research groups as the basis for their own MPI implementations. This BoF session will provide a forum for users of MPICH as well as developers of MPI implementations derived from MPICH to discuss experiences and issues in using and porting MPICH. Future plans for MPICH will be discussed. Representatives from MPICH-derived implementations will provide brief updates on the status of their efforts. MPICH developers will also be present for an open forum discussion.

We have held this BoF in previous years at SC. It has always been well attended (> 50 attendees), and both MPICH developers and users have found it useful. It helps users know where MPICH is going in the near term, and it helps MPICH developers know what changes or improvements users want in the software, thereby enabling them to refine their development plans to better serve the community's needs.
