WSMP (Watson Sparse Matrix Package)

WSMP (Watson Sparse Matrix Package) is a High-Performance Shared- and Distributed-Memory Parallel Sparse Linear Equation Solver. It is robust and easy to use. It can be used as a serial package, in a shared memory environment, or as a scalable solver in a message-passing environment

Overview and Purpose

WSMP (Watson Sparse Matrix Package) is a High-Performance Shared- and Distributed-Memory Parallel Sparse Linear Equation Solver. It is robust and easy to use. It can be used as a serial package, in a shared memory environment, or as a scalable solver in a message- passing environment.

Origin of the software

IBM Research Division T.J.Watson Research Center

Supported Platforms at LRZ

  • Itanium-based systems, including SGI Altix

Please contact LRZ HPC support if you need to use WSMP on other Linux-based platforms at LRZ

Usage

To use the libraries, please first load the appropriate Environment modules:

  module load mkl wsmp

Then, linkage is performed as follows:

  • [ifort|icc] -o myprog.exe myprog.o .... $WSMP_LIB $MKL_LIB
  • [mpif90|mpicc] -o myprog.exe myprog.o .... $WSMP_MPI_LIB $MKL_LIB

The MPI version of the library is selected by platform. On the Altix 4700, the sgi MPT variant is used, on the IA64 cluster systems, the library built with MPICH (e.g., Parastation MPI) is used.
