Sure, I do it all the time. There are a couple strategies. The best one is to use mpirun or mpiexec if it supports MPMD (multiple-program multiple data). That depends on the specific MPI implementation you are using.
The other way is to launch 2 jobs in the background (end the command with a &) and then use the command 'wait' to make the script halt until both jobs are done.
