Web• OpenMP programming is easier than MPI (in general), but it’s still parallel programming, and therefore hard! • application developers need yet another skill set • OpenMP (as with all threaded programming) is subject to subtle race conditions and non-deterministic bugs • correctness testing can be hard

Web(SPEC) has released a suite of OpenMP application bench-marks, called SPEC OMP2001, to evaluate the performance of contemporary SMP systems [1]. The SPEC OMPM2001 suite (referred to as the medium suite) is targeted toward mid-range parallel computers. Some performance results on a number of SMP systems have been reported in [4, 5, 19]. Web2000). However, most of the latest SMP clusters require explicit message passing to carry out communication between nodes. In theory a mixed mode code, with the MPI parallelisation occurring across the SMP boxes and OpenMP parallelisation within the boxes, should be more efficient on an SMP cluster as the model
