Hi, I am trying MPI 4.0.3 and would like to know which is the best way to cleanup the environment after an mpirun execution using Hydra finishes incorreclty. In previous versions (with MPDs) I was doing mpdallexit to ensure all daemons where down. I tried usingI_MPI_HYDRA_CLEANUP environment variable to generate the input file for the mpicleanup tool, but it seems this file is never created. This is how I am running mpi: mpirun -r ssh -f /home/mguzman/wdir/mpd.host -genv I_MPI_FABRICS shm:dapl -env I_MPI_HYDRA_CLEANUP=1 -machinefile /home/mguzman/wdir/machinefile -n 16 /home/mguzman/wdir/test.impi I have read that this file is erased when the job ends, so I tryed to look for that file while the command is being executed, but culdn't find it. Am I doing something wrong? How can I force mpi to fail in order to try mpicleanup tool? Thanks in advance Mateo Guzman
