Portable Data-Parallel Extensions with oneAPI

by Nikita Grigorian and Oleksandr Pavlyk

This poster is intended to introduce writing portable data-parallel Python extensions using oneAPI.

We present several examples, starting with the basics of initializing a USM (unified shared memory) array, then a KDE (kernel density estimation) with pure DPC++/Sycl, then a KDE Python extension, and finally how to write a portable Python extension which uses oneMath.

The examples can be found here.
