PetscGetResidentSetSize

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

Synopsis

#include "petsc.h" 
int PetscGetResidentSetSize(PetscLogDouble *mem)
Not Collective

Output Parameter

mem -memory usage in bytes

Options Database Key

-get_resident_set_size -Print memory usage at end of run
-trmalloc_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 PetscTrSpace() for codes that employ Fortran with hardwired arrays.
