MatMkl_CPardisoSetCntl#

Set MKL Cluster PARDISO parameters https://www.intel.com/content/www/us/en/docs/onemkl/developer-reference-c/2023-2/onemkl-pardiso-parallel-direct-sparse-solver-iface.html

Synopsis#

#include "petscmat.h"  
PetscErrorCode MatMkl_CPardisoSetCntl(Mat F, PetscInt icntl, PetscInt ival)

Logically Collective

Input Parameters#

F - the factored matrix obtained by calling MatGetFactor()
icntl - index of MKL Cluster PARDISO parameter
ival - value of MKL Cluster PARDISO parameter

Options Database Key#

-mat_mkl_cpardiso_ - set the option numbered icntl to ival

Note#

This routine cannot be used if you are solving the linear system with TS, SNES, or KSP, only if you directly call MatGetFactor() so use the options database approach when working with TS, SNES, or KSP. See MATSOLVERMKL_CPARDISO for the options
