Enabling interoperability across U.S. exascale supercomputers is one of the chief goals for the U.S. Exascale Computing Project (ECP), which has broadly overseen development of the early software ecosystem needed to support the new class of supercomputers. Earlier this month, ECP held its annual community BOF days, a virtual event spanning a wide range of topics – including a session on SYCL, which has been gaining momentum as a programming framework for heterogeneous computing.
