The OpenMP implementation of NPB 3.3 (NPB3.3-OMP)
--------------------------------------------------

This directory contains the OpenMP implementation of the NAS
Parallel Benchmarks, Version 3.3 (NPB3.3-OMP). A brief
summary of the new features introduced in this version is
given below.
For changes from different versions, see the Changes.log file
included in the upper directory of this distribution.
For explanation of compilation and running of the benchmarks,
please refer to README.install.
NPB3.3-OMP introduces a new problem size (class E) to seven of
the benchmarks (BT, SP, LU, CG, MG, FT, and EP). The version
also includes a new problem size (class D) for the IS benchmark,
which was not present in the previous releases.
The release is merged with the vector codes for the BT and LU
benchmarks, which can be selected with the VERSION=VEC option
during compilation. However, successful vectorization highly
depends on the compiler used. Some changes to compiler directives
for vectorization in the current codes (see *_vec.f files)
may be required.
OMP/LU-HP (the hyper-plane implementation of LU) is no longer
included in the distribution. To get this version, please
download NPB3.2.1 instead.
