|
|
Note that to mitigate issues like `this <https://github.com/pytorch/pytorch/issues/95606>`_
|
||
|
|
it is thread safe to call this function from multiple threads on the same object.
|
||
|
|
It is NOT thread safe though to call any other function on self without proper
|
||
|
|
synchronization. Please see :doc:`/notes/multiprocessing` for more details.
|
||
|
|
|
||
|
|
.. note::
|
||
|
|
When all references to a storage in shared memory are deleted, the associated shared memory
|
||
|
|
object will also be deleted. PyTorch has a special cleanup process to ensure that this happens
|
||
|
|
even if the current process exits unexpectedly.
|
||
|
|
|
||
|
|
It is worth noting the difference between :meth:`share_memory_` and :meth:`from_file` with ``shared = True``
|
||
|
|
|
||
|
|
#. ``share_memory_`` uses `shm_open(3) <https://man7.org/linux/man-pages/man3/shm_open.3.html>`_ to create a
|
||
|
|
POSIX shared memory object while :meth:`from_file` uses
|
||
|
|
`open(2) <https://man7.org/linux/man-pages/man2/open.2.html>`_ to open the filename passed by the user.
|
||
|
|
#. Both use an `mmap(2) call <https://man7.org/linux/man-pages/man2/mmap.2.html>`_ with ``MAP_SHARED``
|
||
|
|
to map the file/object into the current virtual address space
|
||
|
|
#. ``share_memory_`` will call ``shm_unlink(3)`` on the object after mapping it to make sure the shared memory
|
||
|
|
object is freed when no process has the object open. ``torch.from_file(shared=True)`` does not unlink the
|
||
|
|
file. This file is persistent and will remain until it is deleted by the user.
