Hi Janek,
If you compile your program and produce a class file, does it run using
mpirun -np 1 java matsim-p
Try to compile OpenMPI from source as indicated at
https://www-lb.open-mpi.org/faq/?category=java
Java tends to require more memory, so if using a batch system be sure to
request en
My job successfully spawned a large number of subprocesses via MPI_Comm_spawn,
filling up the available cores. When some of those subprocesses terminated,
it attempted to spawn more. It appears that the latter calls to
MPI_Comm_spawn caused this error:
[n022.cluster.com:08996] [[56319,0],0]
Hi George,
That clarifies all my questions. Thanks for taking the time to answer them!
Sajid,
`--bind-to-core` should have generated the same warning on OSX. Not sure
why this is happening, but I think the real bug here is the lack of warning
when using the deprecated argument.
Btw, the current master does not even accept 'bind-to-core', instead it
complains about 'unrecognized opt
Hi George,
Thanks a lot for the confirmation!
When one uses the deprecated `--bind-to-core` option, is OpenMPI silently
ignoring this on OS X? Would this be indicated with increased verbosity
when using mpiexec?
Thank You,

Hello
OS X doesn't support binding at all, that's why hwloc and OpenMPI don't
support it either.

Hi OpenMPI-developers,
When trying to run a program with process binding and oversubscription
(on a github actions CI instance) with
OMPI cannot support process binding on OSX because, as the message
indicates, there is no OS API for process binding (at least not exposed to
the user-land applications).
George.

Hi OpenMPI-developers,
When trying to run a program with process binding and oversubscription (on
a github actions CI instance) with --bind-to-core, OpenMPI’s mpiexec
executes the programs with no issues.
Noting that --bind-to core is more portable (MPICH’s mpiexec also accepts
it) and that --bin
Hi Howard,
thanks for your reply. I am using version 4.1.2 and I didn't compile with the
mpijavac wrapper. I was hoping that I could maintain some form of our maven
build infrastructure and then deploy the resulting jar. The Project set up is
here: https://github.com/Janekdererste/matsim-p/blob
HI Janek,
A few questions.
First which version of Open MPI are you using?
Did you compile your code with the Open MPI mpijavac wrapper?

Hi,
I am trying to extend an existing Java-Project to be run with open-mpi. I have
managed to successfully set up open-mpi and my project on my local machine to
conduct some test runs.
However, when I tried to set up things on our cluster I ran into some problems.
I was able to run some trivia
