Re: [OMPI users] Problem with MPI_Comm_spawn using openmpi 2.0.x + sbatch

Just to throw this out there -- to me, that doesn't seem to be just a problem with SLURM. I'm guessing the exact same error would be thrown interactively (unless I didn't read the above messages carefully enough). I had a lot of problems running spawned jobs on 2.0.x a few months ago, so I

[OMPI users] bug? "The system limit on number of children a process can have was reached"

Hello everyone, I am using openmpi-1.10.2 and I am using the `spawn_multiple` MPI function inside a for-loop. My program spawns N workers within each iteration of the for-loop, makes some changes to the input for the next iteration, and then proceeds to the next iteration. After a few iterations

Re: [OMPI users] Java-OpenMPI returns with SIGSEGV

gs up or returns with a SIGSEGV." does you mean that a single call hangs, or that at some point during the for loop a call hangs? If you mean the latter, then it might relate to my issue. Otherwise my thread probably won't be helpful. Jason Maldonis Research Assistant of Professor Paul Voyles

[OMPI users] MPI Spawn functionality and core allocation questions

Hi everyone, I am having trouble developing a complicated parallelization algorithm with MPI and I'm hoping for some tips (I am using OpenMPI 1.10.2). I posted the latest problem I ran into on Stack Overflow and got a response from someone saying they don't think it is possible to do the spawn

Re: [OMPI users] memory cg '(null)'

Hi Rizwan, If you need to rewrite your fork system calls, you may want to check out mpi's spawn functionality. I recently found out about it and it's really useful if you haven't heard of it already. I am using it through python's mpi4py and it seems to be working well. Best, Jason Jason
