PetscDeviceContextQueryIdle

Returns whether or not a PetscDeviceContext is idle

Synopsis

#include <petscdevice.h> 
PetscErrorCode PetscDeviceContextQueryIdle(PetscDeviceContext dctx, PetscBool *idle)

Not Collective

Input Parameter

• dctx - The PetscDeviceContext

Output Parameter

• idle - PETSC_TRUE if dctx has NO work, PETSC_FALSE if it has work

Note

This routine only refers a singular context and does NOT take any of its children into account. That is, if dctx is idle but has dependents who do have work this routine still returns PETSC_TRUE.
