Subject: [mpich-devel] MPICH with SYCL on Aurora

Hi
    I am trying to port a simulation ensemble workflow that runs ExaEpi/AMReX/SYCL to Aurora.  The outer workflow uses the system MPI and we use MPICH to run the app with node-local parallelism using a hand-built MPICH.  On Aurora, I get errors in early MPI calls that I think are due to SYCL.  This approach works on NVIDIA systems like Perlmutter.  Is there some simple way to make MPICH aware of SYCL?
    Thanks
