Use flags of 5.3.4-r2
- +cholesky Enable sparse Cholesky factorisation
- cuda Enable NVIDIA CUDA support (computation on GPU)
- doc Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
- openmp Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
- +matrixops Support basic sparse and dense matrix operations (add, multiply, scale, et cetera)
- +modify Enable Cholesky-modification routines like update, downdate, row-add, and row-delete
- +partition Enable graph partitioning and graph-partition-based orderings through sci-libs/metis (using a bundled fork in 4.0.0+) or sci-libs/parmetis
- +supernodal supernodal cholesky factorisation
- test Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)
