torch.mtia

The MTIA backend is implemented out of the tree, only interfaces are be defined here.

This package enables an interface for accessing MTIA backend in python

StreamContext	Context-manager that selects a given stream.
current_device	Return the index of a currently selected device.
current_stream	Return the currently selected Stream for a given device.
default_stream	Return the default Stream for a given device.
device_count	Return the number of MTIA devices available.
init
is_available	Return true if MTIA device is available
is_initialized	Return whether PyTorch's MTIA state has been initialized.
memory_stats	Return a dictionary of MTIA memory allocator statistics for a given device.
get_device_capability	Return capability of a given device as a tuple of (major version, minor version).
empty_cache	Empty the MTIA device cache.
record_memory_history	Enable/Disable the memory profiler on MTIA allocator
snapshot	Return a dictionary of MTIA memory allocator history
set_device	Set the current device.
set_stream	Set the current stream.This is a wrapper API to set the stream.
stream	Wrap around the Context-manager StreamContext that selects a given stream.
synchronize	Waits for all jobs in all streams on a MTIA device to complete.
device	Context-manager that changes the selected device.
set_rng_state	Sets the random number generator state.
get_rng_state	Returns the random number generator state as a ByteTensor.
DeferredMtiaCallError

Streams and events

Event	Query and record Stream status to identify or control dependencies across Stream and measure timing.
Stream	An in-order queue of executing the respective tasks asynchronously in first in first out (FIFO) order.
