A microbenchmark suite for OpenMP 2.0

In this paper we present a set of extensions to an existing microbenchmark suite for OpenMP. The new benchmarks are targeted at directives introduced in the OpenMP 2.0 standard, as well as at the handling of thread-private data structures. Results are presented for a Sun HPC 6500 system, with an early access release of an OpenMP 2.0 compliant compiler, and for an SGI Origin 3000 system.
