PetscMemoryGetMaximumUsage
Returns the maximum resident set size (memory used) for the program.
Synopsis
#include "petscsys.h"
PetscErrorCode PetscMemoryGetMaximumUsage(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.
