Re: [OMPI users] MPI_Init

Hi Ralph, Thanks for taking care of this so quick! Does this mean that MPI_Init will leave the SIGCHLD handler alone? Should it be fine to set the handler as I did in the current version of MPI? Thanks, Tony From: users-boun...@open-mpi.org

Re: [OMPI users] MPI::Intracomm::Spawn and cluster configuration

Hmmm, I went to the build directories of openmpi for my two machines, went into the orte/test/mpi directory and made the executables on both machines. I set the hostsfile in the env variable on the "master" machine. Here's the output:

Re: [OMPI users] MPI::Intracomm::Spawn and cluster configuration

Looks to me like it didn't find your executable - could be a question of where it exists relative to where you are running. If you look in your OMPI source tree at the orte/test/mpi directory, you'll see an example program "simple_spawn.c" there. Just "make simple_spawn" and execute that with

I see. Okay. So, I just tried removing the check for universe size, and set the universe size to 2. Here's my output: LD_LIBRARY_PATH=/home/budgeb/p4/pseb/external/lib.dev:/usr/local/lib OMPI_MCA_orte_default_hostfile=`pwd`/hostsfile ./master_exe [budgeb-interlagos:29965] [[4156,0],0]

Glancing at the code, I don't see anywhere that we trap SIGCHLD outside of mpirun and the orte daemons - certainly not inside an MPI app. What version of OMPI are you using? On Aug 28, 2012, at 2:06 PM, Tony Raymond wrote: > Hi, > > I have an application that uses openMPI

Hi, I have an application that uses openMPI and creates some child processes using fork(). I've been trying to catch SIGCHLD in order to check the exit status of these processes so that the program will exit if a child errors out. I've found out that if I set the SIGCHLD handler before

Ah, I see - yeah, the parameter technically is being renamed to "orte_rsh_agent" to avoid having users need to know the internal topology of the code base (i.e., that it is in the plm framework and the rsh component). It will always be there, though - only the name is changing to protect the

Try using the 1.6.2 nightly snapshot tarball and see if that fixed your problem. I'm not near a computer to give you the specific link - go to openmpi.org and download and nightly snapshots and the v1.6 series. Sent from my phone. No type good. On Aug 28, 2012, at 6:59 AM, "清风"
