Synopsis#
static inline PetscErrorCode PetscTime(PetscLogDouble *v)
Not Collective
Output Parameter#
v - time counter
Usage#
PetscLogDouble v;
PetscTime(&v);
.... perform some calculation ...
printf("Time for operation %g\n",v);
Note#
Since the PETSc libraries incorporate timing of phases and operations, we do not recommend ever using PetscTime()
.
The options database command -log_view
activates PETSc library timing.
See PetscLogStageRegister()
