>From the rank #0 process, I wish to start another mpi job (to create some data to be used by the parent job). I'm trying to do this with the command
istat= system( "/...path.../mpirun -np 2 /...path.../prog2 args >file.log 2>&1" ) within the code executed by the rank #0 process, where ...path... is the path to the executables, prog2 is the daughter program, and args its arguments. On return, the status istat = 256, and, although the log file file.log has been created, it is empty. DOes anybody have an idea why this doesn't work?
