What parallel NAG libraries are there?

Please note: The FAQ pages at the HPCVL website are continuously being revised. Some pages might pertain to an older configuration of the system. Please let us know if you encounter problems or inaccuracies, and we will correct the entries.

The parallel NAG libraries consist of two contributions, namely

  • The NAG Parallel Library which uses MPI to implement scalable versions of numerical operations that lend themselves for parallel execution. This library will typically be used on a cluster. Presently, we do not have this library installed on our machines, as it requires a deprecated component (the S3L libraries) of Sun ClusterTools.
  • The NAG Fortran SMP Library which uses Symmetric Multiprocessor machines for numerical operations that can make use of multiple processors (real or virtual). This library will typically be used on a shared-memory multiprocessor machine.
