Potential performance degradations¶
You might experience performance degradations if you use Lever Zero Runtime for GPU computations.
Note
For more information about Level Zero, refer to Intel® oneAPI DPC++/C++ Compiler Developer Guide and Reference.
How to Fix¶
Switch back to OpenCL runtime by setting the SYCL_BE variable to PI_OPENCL:
export SYCL_BE=PI_OPENCL
