[Ecp-aurora-sdk-discuss] Large slowdown with latest oneapi compiler

Hi everyone, I'm seeing a ~6x overall slowdown for the EXAALT KPP benchmark (LAMMPS SNAP) when switching from oneapi/eng-compiler/2022.01.30.002 to oneapi/eng-compiler/2022.01.30.003. This is using the Kokkos SYCL backend, keeping both Kokkos and LAMMPS versions constant. I profiled the kernels and the most expensive kernel (ComputeYi) became ~10x slower due to the compiler update. Most of the other kernels have similar performance between the two compiler versions. I have set SYCL_PROGRAM_COMPILE_OPTIONS="-ze-opt-large-register-file" but it doesn't seem to have any effect. Any ideas? Thank you, Stan
