Justin, can you provide the specific error? kevin ________________________________________ From: Wozniak, Justin M. via devel <[email protected]> Sent: Monday, March 30, 2026 2:24 PM To: [email protected] Cc: Wozniak, Justin M. 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 -- Justin M Wozniak
