SuperLU

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.

Availability and Restrictions

SuperLU is available on Glenn and Oakley Clusters. It comes in two different flavors: SuperLU_MT (multithreaded) for shared memory parallel machines and SuperLU_DIST for distributed memory parallel machines. The versions currently available at OSC are:

Library	Version	Oakley	notes
SuperLU_MT	2.0	X	Default version on Oakley prior to 09/15/2015
SuperLU_MT	3.0	X*
SuperLU_DIST	3.0	X	Default version on Oakley prior to 09/15/2015

SuperLU is available to all OSC users without restriction.

Usage

Usage on Oakley

Set-up on Oakley

Initalizing the system for use of the SuperLU librarie is dependent on the system you are using and the compiler you are using. To use the SuperLU libraries in your compilation on Oakley, run the following command: module load superlu_mt . or module load superlu_dist . You can use module spider superlu to view available modules on Oakley.

Building With SuperLU on Oakley

Once loaded on Oakley, the SuperLU libraries can be linked in with your compilation. To do this, use the following environment variables:

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
