Most of those same patterns/algorithms are still in use. The most accurate way to determine what is used is to examine the source, particularly the sources in the "src/mpi/coll" directory: http://git.mpich.org/mpich.git/tree/HEAD:/src/mpi/coll -Dave

Inside Collective calls
by m srini 13 Feb '13

Hello sir, I have a small doubt regarding the patterns that the collective calls use. Do they still use the patterns mentioned in the paper "OPTIMIZING MPI COLLECTIVE CALLS" by Rajeev Thakur ? If not please help me in understanding the collective call patterns. Thanks a lot. With warm regards, M.Srinivas

Re: [mpich-discuss] Amazon ec2 Windows machine

Hi, The latest version of MPICH2 on Windows (1.4.1p1) do not have support for shm and ssm channels. Are you sure you are using the latest version of MPICH2 on your machines? Please use the "-channel" option to select the channels ("nemesis"/"sock"). Can you try running the job by setting the environment variable "MPICH_NO_LOCAL" to 1 (mpiexec -n 2 -env MPICH_NO_LOCAL 1 c:\Progra~1\MPICH2\examples\cpi.exe)? This option should force all communication to go via tcp sockets.

Hi Jed, The MPI standard doesn't mandate a particular behavior in case of an error, so doing what the user asked for is also allowed. :) In seriousness, I completely agree on the importance of error checking. The coverage in RMA has improved significantly through the MPI-3 development effort, and we are continuing to work on it. ~Jim.
