PetscMemoryGetCurrentUsage

 Returns the current resident set size (memory used) for the program.

Synopsis

#include "petscsys.h" 
PetscErrorCode  PetscMemoryGetCurrentUsage(PetscLogDouble *mem)
Not Collective

Output Parameter

mem -memory usage in bytes

Options Database Key

-memory_view -Print memory usage at end of run
-malloc_log -Activate logging of memory usage

Notes

The memory usage reported here includes all Fortran arrays (that may be used in application-defined sections of code). This routine thus provides a more complete picture of memory usage than PetscMallocGetCurrentUsage() for codes that employ Fortran with hardwired arrays.
