[OMPI users] Shared Memory - Eager VS Rendezvous

2012-05-22 Thread Simone Pellegrini
Dear all, I would like to have a confirmation on the assumptions I have on how OpenMPI implements the rendezvous protocol for shared memory. If process A sends a message to process B and the eager protocol is used then I assume that the message is written into a shared memory area and picked

[OMPI users] replication in Open MPI

2012-05-22 Thread Thomas Ropars
Dear all, We are starting studying replication for MPI applications. A few papers have been published in the last months on this topic. We were wondering if anybody has already started working on providing process replication in Open MPI ? And if yes, is there some code available ? Best re

Thank you for teaching me google :). By the way I gave the same query before. But this time I made deep search and found 5 to 6 mpi implementations of sorting;) Thanks for your help. But you didn't reply my last question. From: Jeff Squyres To: Mudassar Maje

Dear Jeff,    The algorithms can be like implementation of sorting algorithms using OpenMPI. Secondly, can you name one such MPI-middleware that performs the tuning on runtime for selection of best algorithms (based on the parameters) and composition of parallel applications ?? You
