Hello Tommy,
I'd appreciate to have a quick look at PR 13039 [1] from my student here at
HLRS.
He implemented some message aggregation for partitioned P2P in a new module
based
on our work presented at EuroMPI/Australia last year.
Feedback welcome. :)

Hello Austen,
Unfortunately I could not attend the last telco and therefore I do not know if
this was discussed.
So I'd like to bring up attention for
https://github.com/mpi-forum/mpi-issues/issues/765
It is not voted on yet but seems to have support to go in.
As Partitioned communication is int
e Open MPI documentation could
include some more information and maybe best practices about this.

Works for the installation at HLRS.
Short note/question: I am using the mtt-relay script. This is written in perl.
Is there a python based replacement?

Fetching the tarballs itself works fine.

Hello Ralph,
Thanks for the update on this issue.
I used the latest master (c38866eb392

If I now have a program which calls MPI_File_open, MPI_File_write and
MPI_Abort() in order, I get left over files /tmp/OMPI_*.sm.
Running orte-clean does not remove them.
Is this a bug or a feature?

not think that would be hard to change.
is this a source of problem for your applications ?
note this kind of behavior can be caused by the batch manager.
if you use slurm and srun instead of mpirun, I am not even sure stdout is a
tty.

Hello,
What is the C standard version to be used for the Open MPI code base?
Most seems to be < C99.
C99 features I saw so far mostuly in newer components:
* restrict keyword
* variable declaration inside for loop heads

I see...
Redirecting stdout or stderr to files does not change anything in the Open MPI
case.
Best regards
Christoph Niethammer
PS: MPICH reports in all cases 0 for isatty() on stdout and stderr.
this into master after the svn->git transition?
* Open a bug first
* fork + pull request or
* email patch from git format-patch to devel list?

nteresting idea: Using the approximation from the cited paper we should
only need around 400 MB to store all primes in the int32 range. Potential for
