Steps to Setup a New VO Through GridPP? (Neurogrid example)

This page goes through the setting up of the VO for the INCF in order for them to start taking advantage of the grid.

1: Seek Guidance/Approval GridPP? Management

If the VO is going to be supported in the UK, it must be approved by GridPP? . This should be the first step - contacting GridPP? Management (Jeremy/David Britten?) with details of the work to be undertaken and the amount of CPU/storage required. If the GridPP? Management Board approve the VO and agree to support it, a GGUS ( ticket for tracking the request will be created (e.g.

2: Obtain a Grid Certificate

It is now worth the people setting up the VO getting grid certifcates. These can be requested through the NGS (NES??) Certificate Wizard ( and will involve a new user going to see their local Grid representative with a passport or other form of ID to confirm. This can take up to a week.

3: Decide on a VO name

This is VERY important and should be thought about carefully as it is very difficut (impossible?) to change. The name must be unique and can (should?) be related to an owned/associated domain. More detail can be found at For INCF, as this VO was likely to go beyond the UK, the name was chosen.

4: Fill out the VO registration form

The VO registration form should now be completed:

Most of the fields are self-explanatory. Note that the VO Admin (for which a grid certificate must be available) will be contacted after this has been filled in to confirm all the information, etc. The NGS Acceptable Use Policy can probably be used without problem, but this info can be easily changed afterwards (with the exception of the VO name!).

4: Configure and Add users

After the VO has been setup and the VO Admin notified, the link for registration (hosted by GridPP? in this case) will be made available. It is now a good idea to register the initial users/testers but not the whole VO before everything else is setup. The link will be of the form:

5: Add VO to Operations Portal

Now the VO is setup, but info needs to be added to various other places in order for sites/users to be able to find out the required info about the VO. The first of these is the Operations Portal:

Note that if you are having GridPP? host your VOMS server, this is already been setup and configured in GOCDB. The information given here is pubished on the Operations Website on your VO Card and can be changed afterwards. For the AUP, if you're not sure the boiler plate can be used with minor modifications.

After requesting the VO to be registered you should be emailed with a link to both your new VO Card and a another GGUS ticket to track the registration, similar to:

The ticket will be used by the COD team to sort out any problems with the information given. When complete, you will be informed by email and on the ticket (it will be closed).

6: Add VO to GGUS Portal

The other place where the VO must be registered is in GGUS so sites know who to contact or who is contacting them. The main page for this is at:

You must create another GGUS ticket to do this, similar to:

Thist can take some time (~1 month).

7: Gaining Support at Services

The main central services that the VO should be registered for are the WMS (for job submission) and the LFC (for distributed storage). This may be done by GridPP? management, but if required, tickets should be submitted to the various WMS hosts and LFC host, e.g.:

You will be asked to test this after it's been setup.

8: Request Site support

Finally, you must ask particular sites to support your VO. It is best do this via one of the GridPP? meetings and giving a presentation (unless you are present at a University with a site who are willing to support you). You can then request support at this forum and maybe (if requested) follow up with GGUS tickets against the sites. If asked for, the configuration options for a site can be found at the VOMS server, e.g.:

9: Start using the Grid!

That should enable you to start using the grid as well as submit tickets if there are problems.
