"""The NAS Parallel Benchmarks (NPB) are a small set of programs
designed to help evaluate the performance of parallel supercomputers.
The benchmarks are derived from computational fluid dynamics (CFD)
applications and consist of five kernels and three pseudo-applications
in the original "pencil-and-paper" specification (NPB 1). The benchmark
suite has been extended to include new benchmarks for unstructured
adaptive mesh, parallel I/O, multi-zone applications, and computational
grids. Problem sizes in NPB are predefined and indicated as different
classes. Reference implementations of NPB are available in commonly-used
programming models like MPI and OpenMP (NPB 2 and NPB 3).
