PetscDeviceContextSynchronize#
Block the host until all work queued on a PetscDeviceContext has finished
Synopsis#
#include <petscdevice.h>
PetscErrorCode PetscDeviceContextSynchronize(PetscDeviceContext dctx)
Not Collective
Input Parameter#
dctx - The
PetscDeviceContextto synchronize
Notes#
The host will not return from this routine until dctx is idle. Any and all memory
operations queued on or otherwise associated with (either explicitly or implicitly via
dependencies) are guaranteed to have finished and be globally visible on return.
In effect, this routine serves as memory and execution barrier.
