SuiteSparseQR is an implementation of the multifrontal sparse QR
factorization method.  Parallelism is exploited both in the BLAS and
across different frontal matrices using Intel's Threading Building Blocks,
a shared-memory programming model for modern multicore
architectures.  It can obtain a substantial fraction of the
theoretical peak performance of a multicore computer.

This package is part of SuiteSparse.

This requires a BLAS/LAPACK implementation.  Choose one of these package sets:
 * OpenBLAS (includes both a BLAS and a LAPACK implementation)
 * atlas (includes both a BLAS and a LAPACK implementation)
 * blas, lapack (the Netlib reference implementations)
If more than one set is installed (assuming there are no packaging conflicts)
then the auto-detection will use the first implementation from this list that
it finds.  If in doubt, choose the Netlib reference implementations; other
packages that require a BLAS or LAPACK implementation may not build if they
are not configured to detect/use alternate implementations.
