Global Functions

allocator make_allocator(
    dnnl_graph_sycl_allocate_f sycl_malloc,
    dnnl_graph_sycl_deallocate_f sycl_free
    )

Constructs an allocator from SYCL malloc and free function pointer.

SYCL allocator should be used for SYCL runtime and host allocator should be used for non-SYCL. Currently, only device USM allocator is supported.

Parameters:

sycl_malloc	The pointer to SYCL malloc function
sycl_free	The pointer to SYCL free function

Returns:

Created allocator

sycl::event execute(
    compiled_partition& c_partition,
    stream& astream,
    const std::vector<tensor>& inputs,
    std::vector<tensor>& outputs,
    const std::vector<sycl::event>& deps = {}
    )

Executes a compiled partition in a specified stream and returns a SYCL event.

Parameters:

c_partition	Compiled partition to execute.
astream	Stream object to run over
inputs	Arguments map.
outputs	Arguments map.
deps	Optional vector with sycl::event dependencies.

Returns:

Output event.
