General Usage

SuperLU contains a set of subroutines to solve a sparse linear system A*X=B. It uses Gaussian elimination with partial pivoting (GEPP).

This is the multithreaded implementation of the library. I.e. it can make use of multiple cores on a single node.

Please see superlu for the sequential version.

Please see superlu-dist for a distributed memory/MPI version (i.e can use multiple nodes).

The following environmental variables have been defined:

  • $SUPERLUMT_ROOT has been set to the root of the superlu-mt installation
  • $SUPERLUMT_LIBDIR points to the directory containing the libraries
  • $SUPERLUMT_INCDIR points to the directory containing the header files

You will probably wish to use these by adding the following flags to your compilation command (e.g. to CFLAGS in your Makefile):

  • -I$SUPERLUMT_INCDIR

and the following flags to your link command (e.g. LDFLAGS in your Makefile):

  • -L$SUPERLUMT_LIBDIR -Wl,-rpath,$SUPERLUMT_LIBDIR
