PetscDeviceContextSetDevice#
Set the underlying PetscDevice for a PetscDeviceContext
Synopsis#
#include <petscdevice.h>
PetscErrorCode PetscDeviceContextSetDevice(PetscDeviceContext dctx, PetscDevice device)
Not Collective
Input Parameters#
dctx - The
PetscDeviceContextdevice - The
PetscDevice
Notes#
This routine is effectively PetscDeviceContext’s “set-type” (so every PetscDeviceContext must
also have an attached PetscDevice). Unlike the usual set-type semantics, it is not strictly
necessary to set a contexts device to enable usage, any created PetscDeviceContexts will
always come equipped with the “default” device.
This routine is a no-op if device is already attached to dctx.
This routine may (but is very unlikely to) initialize the backend device and may incur synchronization.
