MATH2OPUS#
“h2opus” - A matrix type for hierarchical matrices using the H2Opus package [ZBT+22].
Options Database Key#
-mat_type h2opus - matrix type to “h2opus”
Notes#
H2Opus implements hierarchical matrices in the \(H^2\) flavour. It supports CPU or NVIDIA GPUs.
For CPU only builds, use ./configure --download-h2opus --download-thrust
to install PETSc to use H2Opus.
In order to run on NVIDIA GPUs, use ./configure --download-h2opus --download-magma --download-kblas
.
