From 0714fee8113e6e4c4d5ef78cf50f1175e2e8bd5f Mon Sep 17 00:00:00 2001 From: Oleksandr Pavlyk Date: Wed, 21 Oct 2020 15:47:02 -0500 Subject: [PATCH 01/49] Memory class exposes __sycl_usm_array_interface__ 1. Memory class exposes the interface 2. Memory variants constructors can consum objects exposing the said interface, and take over memory zero copy. 3. Class implements memInst.copy_to_host(pyobj=None) If `pyobj` supports Python's buffer protocol, content of USM memory in the instance is copied to the host buffer. Otherwise, bytearray is allocated, populated and returned memInst.copy_from_host(pyobj) Copies buffer of `pyobj` into USM memory of the instance. Raises exception if pyobj is not a byte array memInst.copy_from_device(sycl_usm_obj) Copies USM memory of sycl_usm_obj exposing __sycl_usm_array_interface__ into USM memory of the instance 4. Class is pickleable 5. Class implements tobytes method that produces bytes object populated by the content of USM memory. Methods are currently not releasing GIL, but I think they should. --- dpctl/_memory.pxd | 11 +- dpctl/_memory.pyx | 283 ++++++++++++++++++++++++++++++++--- dpctl/tests/test_sycl_usm.py | 54 ++++++- 3 files changed, 321 insertions(+), 27 deletions(-) diff --git a/dpctl/_memory.pxd b/dpctl/_memory.pxd index 2ab5066c8d..d2cee29f77 100644 --- a/dpctl/_memory.pxd +++ b/dpctl/_memory.pxd @@ -29,10 +29,19 @@ cdef class Memory: cdef DPPLSyclUSMRef memory_ptr cdef Py_ssize_t nbytes cdef SyclQueue queue + cdef object refobj -
