Hi everyone I need to daily run an mpi job from a bash script. I have prepared the script and run from the command line, this works fine. But when I try to execute at a later time with at (at -f my_script now +1 minute) the parallel processes do not start. These are the significant parts of my script: # path to mpi executables ruta_mpi=/usr/local/mpich2-1.0.5p4/bin # Function that checks if mpd processes are ok (checks mpdtrace output, five nodes should be up) Comprueba_MPD() { mpdtrace > log.mpd wc -l log.mpd > check.mpd check1=`awk '{ print $1 }' check.mpd` if [ $check1 -eq 5 ]; then echo "Salida de mpdtrace correcta, hosts=$check1" else echo "Salida de mpdtrace incorrecta, hosts=$check1" $ruta_mpi/mpdboot -n 5 & sleep 10 mpdtrace fi } # Run rams60 program with mpirun time $ruta_mpi/mpirun -n 21 ./rams60 -f RAMSIN.operatiu I am sure missing something but I can't find out what's going on.
