Installing CASTEP
For example, with version 20.11:
- You must get the archive file that contains the installer; this file should be named
CASTEP-20.11.tar.gz. - Upload the
CASTEP-20.11.tar.gzfile to your/home/$USERfolder on the cluster you intend to use. - On the cluster, run the command:
[name@server ~]$ eb CASTEP-20.11-iofbf-2020a.eb --sourcepath=$HOME --disable-enforce-checksums
Once this command has completed, log out from the cluster and log back in.
Using CASTEP
You should be able to load the module with:
[name@server ~]$ module load castep
On a compute node, the CASTEP executable can be used like an MPI application:
[name@server ~]$ srun castep.mpi seedname
Where input files would be seedname.cell and seedname.param (i.e. "seedname" could be a different name).
