ICAMM Rennes 2016 HOWTO

Here is a brief tutorial on how to run a calculation and how to run post-traitment tools

• First thing to do:

source the environment via the following command

source /etc/bash.bashrc

• VASP calculations:

3 versions of the VASP code are available:

the so-called standard version which allows you to make standard calculation with several K-points

To use it, enter the following command on a terminal

vasp_std

the so-called non-colinear version which allows you to make non-colinear calculation with several K-points

To use it, enter the following command on a terminal

vasp_ncl

the so-called gamma version which allows you to make gamma calculation but with only 1 K-point

To use it, enter the following command on a terminal

vasp_gam

Please always keep in mind that our local workstation are quite limited so please avoid to run two VASP calculations simultaneously.
