This paper proposes some schemes for the parallelization of a quantum reactive scattering code that integrates a two dimensional
Schrödinger equation. The parallelization is based on both task farm and pipeline models whose processes communicate via the
message-passing paradigm. The various versions of the code are implemented using the Parallel Virtual Machine (PVM) communication
library. Benchmarks of the two proposed parallel models are performed on a CRAY T3E system and the measured performances are
then discussed.
