This quick guide and hands-on walk-through discusses debugging a Message Passing Interface (MPI) based application with GPU offload of SYCL* code onto two GPUs. It provides a simple step-by-step guide to debugging applications that use MPI and GPU offload simultaneously.

In this video we discuss how to debug applications using SYCL--based GPU Offload and Message Passing Interface at the same time. We go into detail on the interaction between MPI and SYCL during the GPU Offload and how the Intel Distribution for GDB manages the program flow. We walk through an example application and cover the debug flow in detail, enabling the developer to directly apply learnings to real-world debug scenarios.
