Hello,
Working with different MPI flavours, I have encountered limits when using
MPI_spawn and threads.
The limit is that the number of spawns that can be made is limited. Over a
given limit the application crashes.
I am trying to overcome the limitation but launching a new process that will
Hi Tim, I get back to you
"What kind of system is it?"
=>The system is a "Debian Sarge".
"How many nodes are you running on?"
=> There is no cluster configured, so I guess I work with no node environnement.
"Have you been able to try a more recent version of Open MPI?"
=>Today, I tried with versio
Maybe the problem comes from the configuration options.
The configuration options used are :
./configure --enable-mpi-threads --enable-progress-threads
--with-threads=posix --enable-smp-locks
Could you give me your point of view about that please ?
Thanks

Do you know if there is a limit to the number of MPI_Comm_spawn we can use in
order to launch a program?
I want to start and stop a program several times (with the function
MPI_Comm_spawn) but every time after 31 MPI_Comm_spawn, I get a "segmentation
fault".
Could you give me your point of you
