Obtaining a New User Account

Kerberos authentication is required in order to access the Lattice QCD computing facilities at Fermilab. For remote users, the following are required:

  • Fermilab Visitor ID
  • Fermilab Kerberos Principal
  • Unix accounts on the LQCD cluster machines

Step 1. Fermilab Visitor ID and Kerberos Principal

If you have previously used computers at Fermilab, you may already have a Visitor ID. Use the Fermilab telephone directory search pages to look for your name. If an entry exists for you and that entry lists a Visitor ID number, record that number for filling out the application form. The details regarding the Visitor ID application process for a Non-Employee Off-Site Fermilab User can be found at this link (please see the section for Off-site Visitors).

If you never had a Fermilab Visitor ID then you will need to submit the online application form for a Visitor ID and Kerberos principal using this link. In the pulldown menu under "Provide your affiliation", select "Lattice QCD". Important - For Fermilab contact name, please list 'Paul Mackenzie'. For Fermilab contact phone, please list 'x3347'. And for Fermilab contact email, please list 'mackenzie@fnal.gov'

If you have requested a CRYPTOCard please go to this link and fill the "Request for Crypto Card" form. We can ship your CRYPTOCard to you.

Step 2. Unix accounts on the LQCD cluster machines

After you have received email with information about your Kerberos principal and CRYPTOCard (if you requested for one), send email to lqcd-admin@fnal.gov to request an account on the LQCD clusters. In the email mention your kerberos principal, identify your project affiliation using the current year allocation table listed here and provide us with your mailing address where we can send your CRYPTOCard to (if you requested for one).

Renewing your Visitor ID and Kerberos principle

Your Fermilab ID and computer privileges expire at different intervals depending on your classification (employee, contractor, on-site or off-site visitor). If you have received an email from the Fermilab Service Desk about a soon to expire or expired Fermilab Visitor ID and computer privileges then follow the two steps listed below to renew your VID and Kerberos principle. Please note that even when your ID and computer privileges expire we do not erase any user data stored on the Fermilab LQCD clusters.

In case you need to find your VID number then use the Fermilab telephone directory search pages to look for your name. If an entry exists for you and that entry lists a Visitor ID number, record that number for filling out the application

Step 1. Re-read the Fermilab Policy on Computing.

Step 2. Fill out this form to renew your Visitor ID. In the pulldown menu under "Provide your affiliation", select "Lattice QCD". Important - For Fermilab contact name, please list 'Paul Mackenzie'. For Fermilab contact phone, please list 'x3347'. And for Fermilab contact email, please list 'mackenzie@fnal.gov'
