in Lam like any other MPI universe whe you you run the job you decide
how many tasks you want to have for example with
mpiexec -n 4 job or
mpirun -np 4 job
you tell the executable job to use 4 processes
Within the program if you want to know how many processes you have you use
call MPI_COMM_SIZE(MPI_COMM_WORLD,size,ierr)
then size which is an integer gives you the number of processes
R.
