SuperLU is a library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. It comes in two different flavors: SuperLU_MT (multithreaded) for shared memory parallel machines and SuperLU_DIST for distributed memory parallel machines.
SuperLU is available to all OSC users without restriction.
The following versions of SuperLU are available on OSC systems:
| Library | Version | Glenn | Oakley |
|---|---|---|---|
| SuperLU_MT | 2.0 | X | |
| SuperLU_MT | 2.3 | X | |
| SuperLU_DIST | 2.3 | X | |
| SuperLU_DIST | 3.0 | X | |
| SuperLU_DIST | 3.1 | X |
SuperLU is available for all compilers on Oakley but only for Intel compilers on Glenn.
To use the SuperLU libraries in your compilation, first load the appropriate superlu module:
On Oakley, use one of these:
module load superlu_mt
module load superlu_dist
On Glenn, you must first load the acml module:
module load acml-intel
then use one of these:
module load superlu-MT-intel
module load superlu-DIST-intel
Once loaded, the SuperLU libraries can be linked in with your compilation. To do this, use the following environment variables:
On Oakley:
| Variable | Use |
|---|---|
$SUPERLU_MT_CFLAGS |
Include path for multithreaded libraries |
$SUPERLU_MT_LIBS |
Link flags for multithreaded libraries |
$SUPERLU_DIST_CFLAGS |
Include path for distributed-memory libraries |
$SUPERLU_DIST_LIBS |
Link flags for distributed-memory libraries |
On Glenn:
| Variable | Use |
|---|---|
$SUPERLU_INC |
Include path |
$SUPERLU_LIBS |
Link flags for either library, depending on loaded module |
