Hi P2P Folk, In terms of an application that can benefit from streams/pipes between MPI processes, the CORAL MCB benchmark (https://asc.llnl.gov/CORAL-benchmarks/) might be a good motivator. This is a stand-in for neutron transport codes where particles move through the domain and could have multiple domain partition crossings (move from one process to another) during a single timestep. Within a timestep, processes poll for incoming particles and send exiting particles to neighboring processes. The communication pattern is data dependent and AFAIK unpredictable. There is effectively a communication pipe between pairs of neighboring processes where the application wants to push/pop particles. ~Jim.

Jeff - Thanks for the reminder. We had a meeting two weeks ago, the notes are on the web page: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/PtpWikiPage There's another meeting at 11:00am Central today. Someone scheduled a meeting I can't reschedule for 10:30 - 11:00 this morning, so I'm going to be 5 minutes late. Call in information is on the Wiki page.

Hi all - We need to have a telecon sometime this month and start planning for September's meeting. Given the short notice, the week of the 8th seemed unlikely to work, so I've created a doodle poll covering the weeks of the 15th and 22nd. Please try to fill out asap. http://doodle.com/nta4b6ngm67xpbi4 Thanks, Brian -- Brian W. Barrett Scalable System Software Group Sandia National Laboratories
