PetscLogHandlerCreate#

Create a log handler for profiling events and stages. PETSc provides several implementations of PetscLogHandler that interface to different ways to summarize or visualize profiling data: see PetscLogHandlerType for a list.

Synopsis#

#include "petscsys.h" 
PetscErrorCode PetscLogHandlerCreate(MPI_Comm comm, PetscLogHandler *handler)

Collective

Input Parameter#

  • comm - the communicator for synchronizing and viewing events with this handler

Output Parameter#

Notes#

This does not put the handler in use in PETSc’s global logging system: use PetscLogHandlerStart() after creation.

See PetscLogHandler for example usage.
