1. Cython/sycl_direct_linkage Example of native extension "cdef import"-ing sycl C++ classes directly from CL/sycl.hpp Queue is created within the function, adding measurable overhead. Extension uses GEMV to compute column-wise total of a C-contiguous matrix, and illustrates linking to oneMKL. 2. Cython/sycl_bufer Example of native extension building on the above, but illustrating getting the queue from dpctl. 3. Cython/usm_memory Example of native extension allocating USM shared memory via dpctl, and using it as a buffer underlying NumPy array. Cython functions dispatches to a SYCL code that works with USM pointer. One function populates USM memory underneath NumPy array with random numbers using ``oneapi::mkl::rng::device`` function used in SYCL kernel, with random number being parameters of European vanilla options. The second function uses SYCL to price these options using Black-Scholes formula.

Is it possible to create makefile for building Cython examples? |
We can add an optional cmake option to build the examples? Should we also add examples for the C API in this folder? |

Each example can be built using |

Could you please update main README.md section Examples too?

Closes #187
This PR reorganizes
examples/folder. The current structure is as follows:Examples in
python/folder intend to show usage ofdpctlfrom Python. Perhaps this folder may also showcase usage ofctypesto interface withDPPLSyclInterfaceshared library.Examples in
cython/folder intend to provide examples of building Cython extensions usingdpctl.Forthcoming examples will show
pybind11as well as SWIG, which will go in their respective folders.
