We describe the performance characteristics of the SPEC OMP benchmarks on parallel vector supercomputers. Points of interest are vectorization, scalability and the comparison between different generations of the same family of NEC SX vector supercomputers. We relate the different performance development of the 11 different applications to different hardware properties of the machine and also to results of the EPCC microbenchmarks. Of special interest is the fact the the NEC SX parallel architecture is not cache consistent.
