The Mean Value Analysis (MVA) algorithm is one of the most popular for eval
uating the performance of separable (or product-form) queueing networks. Al
though its complexity is modest when jobs are indistinguishable, the introd
uction of different customer classes rapidly increases is computational cos
t. The problems of parallelising the algorithm while retaining its conceptu
al simplicity are examined. In particular, a parallel implementation of MVA
on a distributed memory machine is developed using the MPI library for com
munication.
