VASP Licensing at NSC

The terms of the VASP license requires that we verify that a user is covered by a valid VASP license before we can give access to our VASP binaries.

There are three ways in which you can show to us that you are covered by a VASP license:

1. You can be added to one of the licenses that we already have on file. For example, the license holder can contact . See section below, "Updating members in an already registered VASP license".

2. If we don't have the license that you are covered by on file, you can register it with us. Then you must provide a photocopy of the license agreement and the license number. This number is printed on the invoice, so people generally send us a photocopy of the invoice as well. We will then confirm the membership with the VASP developers.

3. If you know that you are covered by a license, but we don't have it on file and you don't have access to the license contract, then we can confirm that you are a registered user with the VASP developers.

To get access, send a request to . Remember to tell us which of the three methods apply to you, and any details needed (e.g your license number or the name and email address that you have registered with the VASP developers).

Please note that this only applies if you want to use the installations of VASP provided by NSC. We highly recommend that you do try out our installations, as they are highly optimized and tested, but you are fully allowed to compile VASP from source yourself, and run it on NSC's clusters. In such cases, you do not need to tell us, but you are responsible for a making sure that your name is on a valid VASP license.

Updating members in an already registered VASP license

After updating the member list at the official VASP portal, ask and other centre supports where you need access to VASP, to do the corresponding update. To do this, provide a list of the emails which was used for registration of the members at the VASP portal. An efficient way to provide this list is to take a screenshot or copy+paste of the license list at the VASP portal. The centres then use the registered emails in order to check the membership.
