PetscDeviceGetAttribute#

Query a particular attribute of a PetscDevice

Synopsis#

#include <petscdevice.h> 
PetscErrorCode PetscDeviceGetAttribute(PetscDevice device, PetscDeviceAttribute attr, void *value)

Not Collective

Input Parameters#

device - The PetscDevice
attr - The attribute

Output Parameter#

value - The value of the attribute

Notes#

Since different attributes are often different types value is a void * to accommodate them all. The underlying type of the attribute is therefore included in the name of the PetscDeviceAttribute responsible for querying it. For example, PETSC_DEVICE_ATTR_SIZE_T_SHARED_MEM_PER_BLOCK is of type size_t.
