MatMumpsSetOocTmpDir

Set MUMPS out-of-core OOC_TMPDIR https://mumps-solver.org/index.php?page=doc

Synopsis

#include "petscmat.h"  
PetscErrorCode MatMumpsSetOocTmpDir(Mat F, const char *tmpdir)

Logically Collective

Input Parameters

• F - the factored matrix obtained by calling MatGetFactor() with a MatSolverType of MATSOLVERMUMPS and a MatFactorType of MAT_FACTOR_LU or MAT_FACTOR_CHOLESKY.

• tmpdir - temporary directory for out-of-core facility.

Note

To make it effective, this routine must be called before the numeric factorization, i.e., PCSetUp(). If ooc_tmpdir is not set, MUMPS will also check the environment variable MUMPS_OOC_TMPDIR. But if neither was defined, it will use /tmp by default.
