Get the current active PetscDeviceContext

Synopsis#

Not Collective

Output Parameter#

Notes#

The user generally should not destroy contexts retrieved with this routine unless they themselves have created them. There exists no protection against destroying the root context.

Developer Notes#

Unless the user has set their own, this routine creates the “root” context the first time it is called, registering its destructor to PetscFinalize().
