PetscDeviceContextDuplicate

Duplicates a PetscDeviceContext object

Synopsis

#include <petscdevice.h> 
PetscErrorCode PetscDeviceContextDuplicate(PetscDeviceContext dctx, PetscDeviceContext *dctxdup)

Not Collective

Input Parameter

• dctx - The PetscDeviceContext to duplicate

Output Parameter

• dctxdup - The duplicated PetscDeviceContext

Notes

This is a shorthand method for creating a PetscDeviceContext with the exact same settings as another. Note however that dctxdup does not share any of the underlying data with dctx, (including its current stream-state) they are completely separate objects.

There is no implied ordering between dctx or dctxdup.

DAG representation
