The '''NAS benchmarksParallel Benchmarks''' isare a set of [[benchmark (computing)|benchmark]]s developed for thetargetting performance evaluation of highly parallel [[supercomputer]]s. They were developed by the [[NASA]] Numerical Aerodynamic Simulation (NAS) Program (now the [[NASA Advanced Supercomputing facility|NASA Advanced Supercomputing Division]]) based at the [[NASA Ames Research Center]].

== Motivation ==

NAS was "Numerical Aerodynamic Simulation programm", which is based at [[NASA]] [[Ames Research Center]].

The NAS Parallel Benchmarks were developed in the early 1990s to address the lack of suitable benchmarks for highly parallel machines. Traditional benckmarks such as the [[Livermore loops]], the [[LINPACK]] benchmark and the original [[NAS Kernel Benchmark Program]], being specialized for vector computers, suffered from inadequacies including parallelism-impeding tuning restrictions and insufficient problem sizes that rendered them inappropriate for highly parallel systems.<ref name=rnr94007>D.

Now it is "NASA Advanced Supercomputing Division".
