Hi,
When launching an application linked with OpenMPI 3.1.1 using the line:
srun --mpi=pmi2 --distribution=arbitrary
--cpu_bind=map_cpu:0,2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,70,72,74,76,78,80,82,84,86,88,90,92,94,96,98,100,102,104
We are seeing a gaping memory leak when running OpenMPI 3.1.x (or 2.1.2, for
that matter) built with UCX support. The leak shows up
whether the “ucx” PML is specified for the run or not. The applications in
question are arepo and gizmo but it I have no reason to believe
that others are not af
Note that what Gilles said is correct: it's not just the dependent libraries of
libmpi.so (and friends) that matter -- it's also the dependent libraries of all
of Open MPI's plugins that matter.
You can run "ldd *.so" in the lib directory where you installed Open MPI, but
you'll also need to "l
Michele, the command is ldd ./code.io
I just Googled - ldd means List dynamic Dependencies
To find out the PBS batch system type - that is a good question!
Try this: qstat --version

Dear John,
Thank you for your reply. I have tried
ldd mpirun ./code.o
but I get an error message, I do not know what is the proper syntax to use ldd
command. Here is the information about the Linux version
$ cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel f
In this case, some Open MPI plugins are missing some third party libraries,
so you would have to ldd all the plugins (e.g. the .so files) located
in /lib/openmpi
in order to evidence any issue.
Cheers,
Gilles

Michele one tip: log into a compute node using ssh and as your own username.
If you use the Modules envirnonment then load the modules you use in
the job script
then use the ldd utility to check if you can load all the libraries
in the code.io executable
Actually you are better to submit a sh
