#include "petscmat.h" PetscErrorCode MatStashSetInitialSize(Mat mat,PetscInt size, PetscInt bsize)Not Collective
| mat | - the matrix | |
| size | - the initial size of the stash. | |
| bsize | - the initial size of the block-stash(if used). |
| -matstash_initial_size <size> or <size0,size1,...sizep | - 1> | |
| -matstash_block_initial_size <bsize> or <bsize0,bsize1,...bsizep | - 1> |
Run with the option -info and look for output of the form MatAssemblyBegin_MPIXXX:Stash has MM entries, uses nn mallocs. to determine the appropriate value, MM, to use for size and MatAssemblyBegin_MPIXXX:Block-Stash has BMM entries, uses nn mallocs. to determine the value, BMM to use for bsize
