Warning: this project is continued at NPB-CPP

🔉 We are happy to announce that both NPB Kernels and pseudo-application are available at our new repository NPB-CPP. 😄

This was our first work on NAS Parallel Benchmark (NPB) suite and many other works are now continuing this project in many different ways.

🔉Note: this repository will no longer be updated, therefore, follow us at NPB-CPP

The NPB-CPP Benchmark

These codes were converted to C++ from the original NPB3.3.1. We achieved similar performance in C++ compared to the Fortran version.

==================================================================

This folder contains:

- NPB-FF - Directory with the parallel version implemented in FastFlow
- NPB-OMP - Directory with the parallel version translated from the original NPB version
- NPB-SER - Directory with the serial version of the NPB ported to C++
- NPB-TBB - Directory with the parallel version implemented in Thread Building Blocks

Each directory is independent and contains its own implemented version of the kernels:

IS - Integer Sort, random memory access
EP - Embarrassingly Parallel
CG - Conjugate Gradient, irregular memory access and communication
MG - Multi-Grid on a sequence of meshes, long- and short-distance communication, memory intensive
FT - discrete 3D fast Fourier Transform, all-to-all communication

Software Requirements

Warning: our tests were made with GCC-5

TBB

Installation

apt-get install libtbb-dev

FastFlow

Installation

svn co https://svn.code.sf.net/p/mc-fastflow/code/ $HOME/fastflow

How to Compile

Enter the directory from the version desired and execute:

make _BENCHMARK CLASS=_VERSION

_BENCHMARKs are:

EP, CG, MG, IS and FT 

_VERSIONs are:

Class S: small for quick test purposes
Class W: workstation size (a 90's workstation; now likely too small)	
Classes A, B, C: standard test problems; ~4X size increase going from one class to the next	
Classes D, E, F: large test problems; ~16X size increase from each of the previous Classes  

Command:

make ep CLASS=B
