Abstract
Within the NICE project, supported by the Dutch Foundation HPCN, the multi-block solver for Navier-Stokes equations ENSOLV is being parallelized. Results of the block-loop parallelization of ENSOLV on a 16 processor NEC SX-4, a shared memory parallel vector computer, are presented and compared to those of low-level DO-loop parallelization implemented earlier. The conclusion is that the block loop parallelization gives better speed-up, requires more memory, and gives overall less execution costs.
