With discrete Intel GPUs entering the high-performance computing landscape, there is an urgent need for production-ready software stacks for these platforms. In this article, we report how we enable the Ginkgo math library to execute on Intel GPUs by developing a kernel backed based on the DPC++ programming environment. We discuss conceptual differences between the CUDA and DPC++ programming models and describe workflows for simplified code conversion. We evaluate the performance of basic and advanced sparse linear algebra routines available in Ginkgo’s DPC++ backend in the hardware-specific performance bounds and compare against routines providing the same functionality that ship with Intel’s oneMKL vendor library.<\/p>\n","protected":false},"excerpt":{"rendered":"
