Taken from Cluster OpenMP* for Intel® Compilers Website
Overview
OpenMP* is a high level, pragma-based approach to parallel application programming. Cluster OpenMP is a simple means of extending OpenMP parallelism to 64-bit Intel® architecture-based clusters. It allows OpenMP code to run on clusters of Intel® Itanium® or Intel® 64 processors, with only slight modifications.
Prerequisite
Cluster OpenMP use requires that you already have the latest version of the Intel® C++ Compiler for Linux* and/or the Intel® Fortran Compiler for Linux*.
Benefits of Cluster OpenMP
- Simplifies porting of serial or OpenMP code to clusters.
- Requires few source code modifications, which eases debugging.
- Allows slightly modified OpenMP code to run on more processors without requiring investment in expensive Symmetric Multiprocessing (SMP) hardware.
- Offers an alternative to MPI. Is easier to learn and faster to implement.
How to Install Cluster OpenMP.
- Installing Cluster OpenMP is simple. First you have to install Intel Compilers. For more information, see Blog Entry Free Non-Commercial Intel Compiler Download
- After installation of the Compilers, download the Cluster OpenMP License File from Cluster OpenMP Download site
- Place the Cluster OpenMP License file at the License Directory. Usually it is at /opt/intel/licenses
- With the Cluster OpenMP license file in place it will make it possible to use either the “-cluster-openmp” or “-cluster-openmp-profile” compiler options with your compiler when compiling a program.
