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)
