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

Output Parameter

mem -memory usage in bytes Many br

Options Database Key

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

Many br

Notes

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