Computing Resources

CELS Systems offers and maintains these general computing resources:

  • A network of workstations (mostly Linux machines), which are the day-to-day desktop computing resources used for editing, electronic mail, text processing, symbolic math programs, and so on.
  • When connecting to CELS resources from offsite you will need to use ssh. Following the linked examples, you can SSH to any of “homes.cels.anl.gov” or various specific compute resources. The “homes.cels.anl.gov” machines are designed only for low impact, interactive use and should never be used to run computations. They are intended to serve as a way for our authenticated users to get into our environment from the outside. Long running or CPU intensive processes should never be run on these machines and if we are alerted that the machine is overloaded we will kill the offending jobs or reboot the machine or both.
  • For access to a system more powerful than your workstation you should see your sponsor/host/supervisor for better alternatives.
  • If you are having trouble finding a machine to run code on you can use any of our standalone compute servers They have the exact same environment as our workstations, but more CPU and memory.  You’ll need a GCE account to use them.
  • Other resources at the lab for long running processes are offered by the Laboratory Computing Resource Center, known as the LCRC. You can find information on the LCRC resources here: Computing and Data Resources.
