CMS Physics Analysis at UW-HEP#

1. Get an AFS Account on Wisconsin computers
2. Register with CERN starting from the “New Member Registration Form” (or pre-registration form) http://cms.cern.ch/iCMS/jsp/secr/reg/regCMS.jsp. The email you get after sending in the above form will ask for a fax or scanned email of the new member’s passport.

3. Follow the advice by completing the registration form sent to you and instructions to contact CMS.Computing@cern.ch to setup a computer account. The form asks for your interests and activity details, among other basic information. You should receive the following instructions:#

   1. To open a Computer Account in CMS (group ZH)
   2. Send an e-mail to cms.computing@cern.ch with all the following information about yourself:
      1. Full family name
      2. First name
      3. Birth date (day-month-year)
      4. For those returning to CERN, your CERN id number if already known - your previous login name (if any, however old)
      5. Preferred login name (min 3, max 8 characters)

4. Request a Grid Certificate#

5. Register with the CMS Virtual Organization (requires CERN registration to be completed)#

6. CMSSW Offline Analysis WorkBook (some work can be done after getting AFS account but grid certificate is needed for using storage services)#

   • Command Cheat Sheet
   • Analysis using CMS Software
     • Local access to UW-Madison Tier-2 Resources.
     • Condor is also available for users submitting jobs directly on Wisconsin Tier-2 machines.

7. FAQ#

Request datasets for Wisconsin via Rucio#

Instructions for Rucio are on the CMS Rucio twiki page.#

It is rare to need a dataset resident on the Wisconsin cluster. Thanks to the AAA/XRootD service, datasets across the CMS grid are accessible to jobs running at Wisconsin. Almost the only time to request a dataset is when it is not on disk anywhere. Before requesting a dataset, be sure to check DAS to find out the status and locations of the dataset. If the dataset is not currently available on disk somewhere, then you can follow the Rucio instructions above to create a rule (subscription) for that dataset at Wisconsin.#
