PCBJKOKKOS#
Defines a preconditioner that applies a Krylov solver and preconditioner to the blocks in a MATSEQAIJ matrix on the GPU using Kokkos
Options Database Key#
-pc_bjkokkos_ - options prefix for its
KSPoptions
Note#
For use with -ksp_type preonly to bypass any computation on the CPU
Developer Notes#
The documentation is incomplete. Is this a block Jacobi preconditioner?
Why does it have its own KSP? Where is the KSP run if used with -ksp_type preonly?
