Hi all, This is a really simple problem (I hope) where I've introduced MPI to a complex numerical model which I have to kill occasionally with Control-C as I don't want it running forever. I have only used mpi_init(), mpi_comm_size(), mpi_comm_rank() and mpi_finalize()- there are no send/receive calls going on at the moment - and I only have two instances. My startup command is:
#/bin/bash /opt/openmpi/bin/mpirun -np 2 -hostfile hostfile jules.exe where hostfile has one entry : localhost The result of terminating the process with Control-C at the command prompt from where I launched it, is that I am then unable to run it again. I get the "mpirun has exited due to process rank 0 with PID 10094 on node metclcv10.local exiting improperly. There are two reasons this could occur:..." error each time despite checking running processes for stragglers, closing my terminal, or changing node. I have spent several hours searching for an answer to this, if it's already somewhere then please point me in the right direction. many thanks in advance Jane For info: #ompi_info -v ompi full --parsable package:Open MPI root@centos-6-3.localdomain Distribution ompi:version:full:1.6.2 ompi:version:svn:r27344 ompi:version:release_date:Sep 18, 2012 orte:version:full:1.6.2 orte:version:svn:r27344 orte:version:release_date:Sep 18, 2012 opal:version:full:1.6.2 opal:version:svn:r27344 opal:version:release_date:Sep 18, 2012 mpi-api:version:full:2.1 ident:1.6.2 I'm using centos-6-3 and FORTRAN.
