An Update on Aurora Exascale Readiness at Argonne

For a number of years, Intel has provided the Advisor and VTune performance profiling software for CPU-based Intel architectures. In advance of the delivery of the ALCF's Intel-HPE exascale system, Aurora, in 2022, Intel has been extending those tools to its Xe GPU architecture. Because the Aurora software development kit (SDK) incorporates multiple major programming models-such as DPC++/SYCL, OpenMP Target offloading (for C, C++ and Fortran), OpenCL, Kokkos, and RAJA-those tools need to be tested across every combination of programming model. Many important applications being developed under DOE's Exascale Computing Project (ECP) integrate Intel's optimized math libraries to maximize their performance; it is therefore crucial that Advisor and VTune are able to capture their performance characteristics seamlessly.
