You can run the post_convert utility in parallel to accelerate your workflow. The command line syntax depends on your operating system and the MPI implementation, and it is identical to running converge in parallel. For example, if your system runs Linux with MPICH, type
mpiexec –n <number of processors> converge
If you want to run a four-processor post_convert job, use the same MPI syntax
mpiexec –n 4 post_convert convert.in
