The '''NAS Parallel Benchmarks''' ('''NPB''') are a set of [[benchmark (computing)|benchmark]]s targeting performance evaluation of highly [[Parallel computing|parallel]] [[supercomputer]]s. They are developed and maintained by the [[NASA]] [[NASA Advanced Supercomputing Division|Advanced Supercomputing (NAS) Division]] (formerly the NASA Numerical Aerodynamic Simulation Program) based at the [[NASA Ames Research Center]]. NAS solicits performance results for NPB from all sources.<ref name="npbweb">{{cite web

==History==

===Motivation===

Traditional benchmarks that existed before NPB, such as the [[Livermore loops]], the [[LINPACK|LINPACK Benchmark]] and the [http://www.netlib.org/benchmark/nas NAS Kernel Benchmark Program], were usually specialized for vector computers. They generally suffered from inadequacies including parallelism-impeding tuning restrictions and insufficient problem sizes, which rendered them inappropriate for highly parallel systems. Equally unsuitable were full-scale application benchmarks due to high porting cost and unavailability of automatic software parallelization tools.<ref name="rnr94007">{{Citation
