In this webinar we demonstrate how an existing CUDA stencil application code can be migrated to DPC++ with the help of the Compatibility Tool. We highlight and discuss the crucial differences between the two programming environments in the context of migrating the tsunami simulation easyWave. The discussion also includes steps for making the code to compliant with the SYCL standard. During the talk, we also show that the migrated code can run on a wide range of platforms starting from CPUs, over GPUs, to FPGAs.
