There are two ways to use GPAW on Niflheim. You can use a preinstalled GPAW, or you can compile it yourself (the latter is mainly for GPAW developpers).
If you compile it yourself, please refer to the guide Compiling GPAW on Niflheim.
If you want to run a precompiled module, please read Loading GPAW modules on Niflheim.
If you want to learn how to run GPU version of GPAW, plese read Running with A100 nodes on Niflheim. Ffor now, there are now precompiled modules, so you need to build GPAW yourself.
