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. </longdescription> <use> <flag name="metis">Use <pkg>sci-libs/metis</pkg> or <pkg>sci-libs/parmetis</pkg> for partitioning</flag> <flag name="tbb">Enable multithreading with the Intel Threads Building Block <pkg>dev-cpp/tbb</pkg></flag> </use> </pkgmetadata>
