A finite‐element study of two‐ and three‐dimensional incompressible viscoelastic flows in a planar lid‐driven cavity and concentric rotating cylinders is presented. The hardware platforms consist of both homogeneous and heterogeneous clusters of workstations. A semi‐implicit time‐stepping Taylor–Galerkin scheme is employed using the message passing mechanism provided by the Parallel Virtual Machine libraries. DEC‐alpha, Intel Solaris and AMD‐K7(Athlon) Linux clusters are utilized. Parallel results are compared against single processor (sequentially) solutions, using the parallelism paradigm of domain decomposition. Communication is effectively masked and practically ideal, linear speed‐up with the number of processors is realized. Copyright © 2002 John Wiley & Sons, Ltd.
