  • LPC Computing quick links - find setup documentation and troubleshooting information for most cmslpc issues
  • Community support mailing list: lpc-howto (click here to self-subscribe)
  • Submit a trouble ticket with ServiceNow, for example if you are having technical problems with your account or something is broken that was working before.

    • Use your Fermilab services username and password
    • You can use the "General Requests"... "General Request" category to put in a Request, mention specifically the cmslpc cluster, and be sure to put in your experiment in the pull-down menu as E-892/919 (CMS)
    • Otherwise, scroll down to the "Scientific Computing" category and choose the right ticket type, see categories below, do NOT try to choose additional categories in most cases:
    • Show possible Scientific Computing categories for cmslpc + Hide -

      Possible Scientific Computing categories

      • "CMS Storage Space Request": for creating an EOS area, getting your grid certificate properly mapped, or increase in EOS quota
      • "Add Account to LPC Group": for adding your FNAL account to a LPC Physics group area
      • Anything else: "Create a New Scientific Computing Request using SCD Catalog": choose "Batch Job Management (jobsub condorsubmit)": that is the on call group for the cmslpc who will triage the problem and fix it or send it to the right sub-group to be fixed.
      • Do not try to choose any other categories for cmslpc issues, as your ticket may not be handled in a timely fashion. The group that handles problems is either:
      • Be sure to put in your experiment in the pull-down menu as E-892/919 (CMS)
      • Show Experiment choice details + Hide -

        Experiment choice details

        • In a non-pull down menu in ServiceNow, you can type *CMS and stop typing and it will bring up choices of which E-892/919 (CMS) is the first
        • Click on the magnifying glass icon to the right, and then you can type CMS in the separate search menu window which opens, E-892/919 (CMS) should be the first option
        • Note that putting CMS and then clicking the magnifying glass icon searches by "Name starts with" and won't find E-892/919 (CMS), so you should use the above options
    • You can also contact the Fermilab Service Desk at the ground floor of Wilson Hall 8 a.m. - 5 p.m. Monday-Friday, or phone (630) 840-2345
  • LPC System Status monitors including News/downtimes
  • Every other Friday LPC Computing Discussion Group - indico link requires CMS CERN account to access
