sci@gentoo.org Gentoo Science Project 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. It can obtain a substantial fraction of the theoretical peak performance of a multicore computer.
