Detailed Description

this file provides three C++ memory allocators using SYCL specific memory allocation functions.

SYCLManagedAllocator allocates SYCL shared memory SYCLAllocator allocates SYCL device memory SYCLHostAllocator allocates SYCL host memory They are based on CUDA*Allocator implementation
