Prerequisites
GPAW needs Python3 and ASE for proper execution. At HLRN, corresponding environment modules (anaconda3 and ase, respectively) must be loaded first. For its MPI-parallel execution GPAW was linked against Intel-MPI 2019, so one of the impi/2019.* environment modules must also be loaded to provide the mpirun job starter.
Only members of the gpaw user group have access to GPAW installations provided by HLRN. To have their user ID included in this group, users can send a message to their consultant or to HLRN our support.
Modules
The environment modules shown in the table below are available to include GPAW in the user's shell environentenvironment. To see what is installed and what is the current default version of GPAW, an overview can be obtained by saying module avail gpaw.
| GPAW version | GPAW modulefile | GPAW requirements |
|---|---|---|
| 20.1.0 | gpaw/20.1.0 (Lise only) | anaconda3/2019.10, ase/3.19.1, impi/2019.* |
When a gpaw module has been loaded successfully, the command gpaw info can be used to show supported features of this GPAW installation.
