Distributed computing techniques offer the potential to significantly
reduce the run time of transmission-line-matrix (TLM) calculations. Th
is letter describes the implementation of a TLM model of a two-channel
waveguide distributed across a network of workstations using parallel
virtual machine (PVM). The methods for distributing the TLM matrix ac
ross the workstations and the effect on performance of different appro
aches are described and discussed.
