PetscMallocSetDRAM

 Set PetscMalloc to use DRAM. If memkind is available, change the memkind type. Otherwise, switch the current malloc and free routines to the PetscMallocAlign and PetscFreeAlign (PETSc default).

Synopsis

#include "petscsys.h"   
PetscErrorCode PetscMallocSetDRAM(void)
Not Collective

Notes

This provides a way to do the allocation on DRAM temporarily. One can switch back to the previous choice by calling PetscMallocReset().
