Hi, I am using the OpenMPI v1.4a1r22335 to run an MPI application that creates dynamically processes. The application behavior is like explained in a previous e-mail http://www.open-mpi.org/community/lists/users/2009/12/11540.php
The application is launched by a command line such as: $ mpirun -hostfile myhosts -np 1 myapp myhosts describes 2 nodes: node1 slots=8 node2 slots=8 My application runs as expected creating dynamic processes into the two nodes. After compute, all processes (static and dynamic ones) finalizes too -- confirmed looking 'top' and 'ps' commands. But, the mpirun remains running and the application never liberate the shell. I try use mpiexec, but it also hangs. If I run locally (without -hostfile), the mpirun does not hang! Someone could help me?! For awhile, I create a script to kill the mpirun to enable the execution of many consecutive mpirun calls, but it is not a "beautiful" solution :) thanks márcia
