Hi:
I am running an application (OpenFOAM) with 20 processors using Ubuntu
16.04 and occasionally mpirun exits with an exit code of 65. I looked at
the documentation and it says:
MPI_T_ERR_PVAR_NO_STARTSTOP
65 Variable cannot be started or stopped.
The m
Diego,
Yes, that would be clearly an issue.
Cheers,
Gilles

If your are trying to create a communicator containing all node local processes
then use MPI_Comm_split_type.

Deal all,
probably I have found the error.
Let's me check. Probably I have not properly set-up colors.
Thanks a lot,
I hope that you have not lost too much time for me,
I will let you know If that was the problem.
Thanks again

Dear R, Dear all,
I do not know.
I have isolated the issues. It seem that I have some problem with:
CALL
MPI_COMM_SPLIT(MPI_COMM_WORLD,colorl,MPIworld%rank,MPI_LOCAL_COMM,MPIworld%iErr)
CALL MPI_COMM_RANK(MPI_LOCAL_COMM, MPIlocal%rank,MPIlocal%iErr)
CALL MPI_COMM_SIZE(MPI_LOCAL_COMM, MPIloca
Those two command lines look exactly the same to me - what am I missing?

Dear all,
I am experiencing a strange error.
In my code I use three group communications:
MPI_COMM_WORLD
MPI_MASTERS_COMM
LOCAL_COMM
which have in common some CPUs.
when I run my code as
mpirun -np 4 --oversubscribe ./MPIHyperStrem
I have no problem, while when I run it as
mpirun -np 4 --ov
Dear Gilles, dear all,
I do not remember.
I use -r8 when I compile.
What do you think?
It could be a problem?
Thanks a lot

The equivalent MCA param is rmaps_base_oversubscribe=1. You can add
OMPI_MCA_rmaps_base_oversubscribe to your environ, or set
rmaps_base_oversubscribe in your default MCA param file.

The buffer being overrun isn’t anything to do with you - it’s an internal
buffer used as part of creating the connections. It indicates a problem in OMPI.
The 1.10 series is out of the support window, but if you want to stick with it
you should at least update to the last release in that series
Hello,
I have this piece of code:
MPI_Comm icomm;
INFO << "Accepting connection on " << portName;
MPI_Comm_accept(portName.c_str(), MPI_INFO_NULL, 0, MPI_COMM_SELF, &icomm);
and sometimes (like in 1 of 5 runs), I get:
[helium:33883] [[32673,1],0] ORTE_ERROR_LOG: Data unpack would read past end
Hello,
I can use --oversubscribe to enable oversubscribing. What is OpenMPI way to set
this as a default, e.g. through a config file option or an environment variable?
Thanks,
Florian
