# GPU plugin Level Zero support

OpenVINO GPU plugin can be compiled with **experimental** Level Zero support. When enabled, plugin will use Level Zero as GPU compute API instead of OpenCL.

## How to build with Level Zero support

1. Configure cmake with the following additional option:
- `-DGPU_RT_TYPE=L0`
2. Build OpenVINO
- `cmake --build . --config Release`

## How to check what runtime is used

1. Set `OV_VERBOSE=1` environment variable
2. Run workload
3. Find what variant of stream is reported in the logs (`ze_stream` or `ocl_stream`)
- Example output for Level Zero runtime: `ze_stream: [GPU] Created L0 stream`
