+| `SYCL_UR_USE_LEVEL_ZERO_V2` | Integer | Enable ('1') or disable ('0') the use of the Level Zero V2 adapter, which features a redesigned architecture aimed at optimizing performance for different queue modes (immediate/batched, in-order/out-of-order). This version is expected to reduce runtime overhead and currently only support immediate command lists. By default, this adapter is used on platforms with GPUs based on the Xe2 architecture or later, such as Battlemage, Lunar Lake, and Arrow Lake. If you experience any performance or functional issues with this adapter enabled, please report them on GitHub, specifying the adapter used. |
