I've seen some failures on SunSpot with the fluids examples. The general behavior is:
/gpu/sycl/ref passes fine everytime
/gpu/sycl/shared fails about 90% of the time
/gpu/sycl/gen fails about 10% of the time
The failures are only present on a few tests (SunSpot is down for maintenance today, so I can't confirm which ones exactly right now, but I'm fairly certain the Gaussian wave tests are one of them), but the above behavior is pretty consistent. This is observed using the oneapi/release/2024.04.15.001.
The failure specifically is a non-linear solver divergence:
[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------
[0]PETSC ERROR: TSStep has failed due to DIVERGED_NONLINEAR_SOLVE, increase -ts_max_snes_failures or make negative to attempt recovery
Given the relationships between the backends, I'm guessing the error is probably in the shared functions between the shared and gen backends.
