Hi,
I'm trying to solve a memory leak since my new implementation of
communications based on MPI_AllToAllW and MPI_type_Create_SubArray
calls. Arrays of SubArray types are created/destroyed at each time step
and used for communications.
On my laptop the code runs fine (running for 15000 temporal

Hi,
I'm using an old (but required by the codes) version of hdf5 (1.8.12) in
parallel mode in 2 fortran applications. It relies on MPI/IO. The
storage is NFS mounted on the nodes of a small cluster.
With OpenMPI 1.7 it runs fine but using modern OpenMPI 3.1 or 4.0.5 the
I/Os are 10x to 100x slowe

Hi Ha Chi
do you use a batch scheduler with Rocks Cluster or do you log on the
node with ssh ?
If ssh, can you check that you can ssh from one node to the other
without password ?
Ping just says the network is alive, not that you can connect.

Hi all,
I've built OpenMPI 4.3.0 with GCC 9.3.0 but on the server ucx was not
available when I set --with-ucx. I remove this option and it compiles
fine without ucx. However I have a strange behavior as when using mpirun

I have also this problem on servers I'm benching at DELL's lab with
OpenMPI-4.0.3. I've tried a new build of OpenMPI with "--with-pmi2". No
change.
Finally my work around in the slurm script was to launch my code with
mpirun. As mpirun was only finding one slot per nodes I have used

Hi OpenMPI maintainers,
I have temporary access to servers with AMD Epyc processors running RHEL7.
I'm trying to deploy OpenMPI with several setup but each time "make

Hi David,
could you specify which version of OpenMPI you are using ?
I've also some parallel I/O trouble with one code but still have not
investigated.

Hi,
I fall in a strange problem with OpenMPI 3.1 installed on a CentOS7
laptop. If no network is available I cannot launch a local mpi job on
the laptop:

I have downloaded the nightly snapshot tarball of october 10th 2018 for
the 3.1 version and it solves the memory problem.
I ran my test case on 1, 2, 4, 10, 16, 20, 32, 40, and 64 cores
successfully.
This version also allows to compile my prerequisites libraries, so we
can use it out of the box to
eds more memory he has to request 2
cores, even if he uses a sequential code. This avoid crashing jobs of
other users on the same node with memory requirements. But this is not
configured on your node.

I do not know about your code but:
1) did you check stack limitations ? Typically intel fortran codes needs
large amount of stack when the problem size increase.
Check ulimit -a
