IML package provides efficient routines to solve nonsingular systems of linear equations, certified solve any shape systems of linear equations, and perform mod p matrix operations, such as computing row-echelon form, determinant, rank profile, inverse of a mod p matrix.

ATLAS is tuned to the compilation host; its use in
systems using precompiled binaries is therefore limited.
Therefore, a generic BLAS that's also faster to build (openblas/cblas) is used for openSUSE.

MPIR is an open source multiprecision integer library derived from version 4.2.1 of the GMP (GNU Multi Precision) project (which was licensed LGPL v2+).

MPIR is constructed by a developer and vendor friendly community of professional and amateur mathematicians, computer scientists and hobbyists.
