This is suite of functions for manipulating sparse matrices. Please look at the SuiteSparse homepage for details about usage and available functions.

Setting the module environment

When you log in, you should load your preferred compiler module, the Intel compiler is loaded by default. As the SuiteSparse functions depend on BLAS and LAPACK, you will also need to load an implementation of these libraries, several are installed on the system. For example, if you would like to use the PGI compiler and MKL, Intel’s implementation of the numerical libraries, use:

This will add the packages appropriate for your chosen environment.
