Ray tracing package that makes use of ospray. While ospray test is cpu centric, the first 18 of 36 tests fail because the GPU SYCL code isn’t enabled. Otherwise it runs a variety of different tests with a remarkably uniform profile.
AMD metrics show floating point code with mostly backend time (split between CPU and memory).
