![]() Parallelization of NAS Benchmarks for Shared Memory Multiprocessors New NPB2 features: New implementation (CG), new workstation class problem sizes, new serial sample versions, more performance statistics. Together these results provide an insightful comparison of the real-world performance of high-performance computers. Because they have not been optimized by vendors, NPB2 implementations approximate the performance a typical user can expect for a portable parallel program on distributed memory parallel computers. NPB2 results complement, rather than replace, NPB results. NPB2 programs are run with little or no tuning, in contrast to NPB vendor implementations, which are highly optimized for specific architectures. NPB2 ( NAS (NASA Advanced Supercomputing) Parallel Benchmarks 2) is an implementation, based on Fortran and the MPI (message passing interface) message passing standard, of the original NAS Parallel Benchmark specifications. Yarrow, Maurice Saphir, William VanderWijngaart, Rob Woo, Alex Kutler, Paul (Technical Monitor) In this way many of the difficulties associated with conventional benchmarking approaches on highly parallel systems are avoided. The principal distinguishing feature of these benchmarks is their 'pencil and paper' specification-all details of these benchmarks are specified only algorithmically. Together they mimic the computation and data movement characteristics of large-scale computational fluid dynamics applications. These consist of five ' parallel kernel' benchmarks and three 'simulated application' benchmarks. ![]() S.Ī new set of benchmarks has been developed for the performance evaluation of highly parallel supercomputers in the framework of the NASA Ames Numerical Aerodynamic Simulation ( NAS) Program.
