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_info  -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.
