This version of benchmarks IS, DT and EP contain special
tweaks to work with SMPI.

-The MPI implementation of NPB 3.3 (NPB3.3-MPI)
---------------------------------------------------
-
For problem reports and suggestions on the implementation,
please contact:
http://www.nas.nasa.gov/Software/NPB
-This directory contains the MPI implementation of the NAS
-Parallel Benchmarks, Version 3.3 (NPB3.3-MPI). 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. For a special note on DT, please
-see the README file in the DT subdirectory.

-
-New features in NPB3.3-MPI:
- * NPB3.3-MPI 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, it should be noted that 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.
-
- * New improvements to BTIO (BT with IO subtypes):
- - added I/O stats (I/O timing, data size written, I/O data rate)
- - added an option for interleaving reads between writes through
- the inputbt.data file. Although the data file size would be
- smaller as a result, the total amount of data written is still
- the same.
