Loading/Compiler affinity¶
Warning
Currently, it is not possible to compile the XZ source code against NVIDIA HPC SDK. In case you need to link your code compiled with NVIDIA HPC SDK against XZ, use the GCC build.
Each version of XZ installed in the public software repository is built against three compiler sets: (i) Intel oneAPI, (ii) AMD Optimized Compiler Collection (AOCC), and (iii) GNU Compiler Collection (GCC). The name of the environmental module contains the name of the compiler set employed for compiling the XZ source code.
Intel oneAPI¶
module avail xz/*/*intel
NVIDIA HPC SDK¶
Note
Use the GCC build (see below)
AOCC¶
module avail xz/*/*aocc
GCC¶
module avail xz/*/*gcc
