Diagnostics by computational region. Basic parallel operation is implemented. Particle passing is implemented. Cross-region field solve is implemented. TE and TM waves, and beams propagate across the interface properly.
Fields seen by particles near virtual boundaries are slightly improper.
MPI MPI is a portable communications package. It supports communication between processes on may different platforms, including networked workstations, MPP machines, and SMP machines. Automated load balancing. Partition assignment according to network topology.
