dpctl.memory.MemoryIPCDevice

class dpctl.memory.MemoryIPCDevice

Class representing memory object backed by an IPC-mapped USM device pointer.

This class is not intended to be instantiated directly.

Methods

copy_from_device(sycl_usm_ary)	Copy SYCL memory underlying the argument object into the memory of the instance
copy_from_host(obj)	Copy content of Python buffer provided by obj to instance memory.
copy_to_host([obj])	Copy content of instance's memory into memory of obj, or allocate NumPy array of obj is None.
get_usm_type([syclobj])	Returns the type of USM allocation using dpctl.SyclContext carried by syclobj keyword argument.
get_usm_type_enum([syclobj])	get_usm_type(syclobj=None)
memset([val])	Populates this USM allocation with given value.
tobytes()	Constructs bytes object populated with copy of USM memory.

Attributes

is_closed	Whether the IPC mapping has been closed.
nbytes	Extent of this USM buffer in bytes.
reference_obj	Reference to the Python object owning this USM buffer.
size	Extent of this USM buffer in bytes.
sycl_context	dpctl.SyclContext the USM pointer is bound to.
sycl_device	dpctl.SyclDevice the USM pointer is bound to.
sycl_queue	dpctl.SyclQueue with dpctl.SyclContext the USM allocation is bound to and dpctl.SyclDevice it was allocated on.
__sycl_usm_array_interface__	Dictionary encoding information about USM allocation.
