EPSSCALAPACK#
EPSSCALAPACK = “scalapack” - A wrapper to ScaLAPACK eigensolvers [Blackford et al., 1997].
Notes#
Only available for Hermitian problems, using subroutines pdsyev and
pdsygvx and the analogs for other precisions.
This is a direct eigensolver, that is, the full spectrum is computed.
The computation involves redistributing the matrices from PETSc storage
to ScaLAPACK distribution, and vice versa (this is done automatically
by SLEPc). Alternatively, the user may create the problem matrices
already with type MATSCALAPACK.
