Loading/Compiler affinity¶
Warning
Currently, it is not possible to compile the XZ source code against NVIDIA HPC SDK (former PGI Compilers). In case you need to link your code compiled with NVIDIA HPC SDK (former PGI Compilers) against XZ, use the LLVM build.
Each version of XZ installed in the public software repository is built against the following compiler collections: (i) LLVM Compiler Infrastructure, (ii) NVIDIA HPC SDK (former PGI Compilers), (iii) Intel oneAPI, (iv) AMD Optimized Compiler Collection (AOCC), and (v) GNU Compiler Collection (GCC). The name of the environmental module contains the name of the compiler set employed for compiling the XZ source code.
