Level-Zero on Aurora
Overview
The objective of the ‘oneAPI’ Level-Zero Application Programming Interface (API) is to provide direct-to-metal interfaces to offload accelerator devices. Its programming interface can be tailored to any device's needs and can be adapted to support a broader set of language features such as function pointers, virtual functions, unified memory, and I/O capabilities.
Setting the environment to use Level-Zero on Aurora
The Intel Programming Environment is the main environment on Aurora. The Intel Compute Runtime is part of this environment and grants access to Level-Zero. The Intel Compute Runtime is loaded by default in your environment.

Building on Aurora
Level-Zero is a C API that can be used in your application by including the
ze_api.h file:
Applications that use the Level-Zero API need to be linked to the Level-Zero
loader library by using the -lze_loader linker flag.
