Intel oneAPI
The Intel oneAPI effort seeks to provide a unified cross-architecture programming model. It takes a toolkit-based approach. The linked site also points to release notes, documentation, etc.
Intel oneAPI Base, HPC and AI toolkits
Intel provides oneAPI toolkits in form of oneAPI Base, HPC or AI toolkits.
On most LRZ systems, Intel oneAPI Base and HPC toolkits are provided with a unified intel-toolkit modules.
Notes
Fortran and C/C++ compilers comprise both traditional and new, LLVM-based compiler drivers:
- traditional:
ifort, icc, icpc
- LLVM-based ("next-gen"):
ifx, icx, icpx, dpcpp
Loading any version of intel-toolkit module will auto-load most oneAPI components. A few components are also made available to you in the environment, you can look at all the available modules via, "module avail" after loading the intel-toolkit module.
These are the intel-oneapi components and its versions provided in the intel-oneapi-toolkit wrapper modules,
