In Part two of the Data Parallel C++ (DPC++) overview series, software engineer Anoop Madhusoodhanan Prabha discusses the best practices for using this language to program oneAPI applications.

DPC++ is part of the oneAPI initiative and provides an open, cross-industry alternative to single-architecture, proprietary languages. Based on familiar C++ and incorporating SYCL* from The Khronos Group*, DPC++ lets developers more easily port code across various architectures from an existing application’s code base.

With that capability comes unique considerations such as how data should be made available on the device side, and the need for synchronization points between compute kernels running across a host and devices to ensure accurate results and deterministic behavior.

Take the next step in learning DPC++ by joining Anoop as he explains:

  • How to efficiently use buffers, sub-buffers, and unified shared memory
  • The in-depth implicit synchronization points in DPC++
  • The atomics, mutex, work-group barriers, and work-group mem-fence
