NERSC Computing Systems

  • At NERSC, we have two supercomputers that you’ll be using this week: Edison and Cori.
  • Edison, a Cray X030, consists of 5586 nodes, each with two, 12-core Ivy Bridge Intel processors and 64GB DDR3 memory. For more info on using Edison. please see:
  • Cori, a Cray XC40, has two types of nodes:
    • There are 2388 “Haswell” nodes, each with two, 16-core Haswell Intel processors and 128GB DDR4 memory, and
    • 9688 “KNL” nodes, each with a 68-core Intel Knight’s Landing (KNL) processors and 16 GB MCDRAM plus 96 GB DDR memory.
  • For more info on using Cori, please see:
  • Logging In
    • Simply use ssh from a command prompt to log in to Edison or Cori:
    • ssh
    • ssh
  • Running Jobs
    • We use the SLURM batch system. You can use our job script generator to create a script that will run on our systems.
    • If your instructors have put in place a reservation for the lesson, you may access that reservation with ——reservation=nameofreservation . Either add this to your script or your job submit line:
    • #SBATCH ——reservation=nameofreservation (batch script)
    • Or
    • sbatch —-reservation=nameofreservation ./mybatchscript
  • Account Life
    • Your account is active from June 30 until Monday, July 3 at noon Pacific time, when we will reset the passwords and wipe the account directories.

TACC Computing System

Information about the Stampede2 system:

We have reserved 300 nodes on Stampede2 for exclusive use by institute attendees. The slurm reservation id is "S2PI"
Students, instructors, and support staff will be able to use the reserved nodes by adding
to the sbatch command and submitting to the normal queue.
Additionally, a single node with interactive access can be requested by using the "idev" command. This will provide a default 30 minute interactive session on a single node where exercises can be done. Since we were able to secure 1 node for each training account, this may be the easiest way for students to do hands on work on Stampede2.

Qwiklabs on Amazon

Everyone who registered at one of the sites is pre-registered. When you login to (starting Wednesday) you will find the class you registered for (there's actually 5 different ones by location, but you will only see one). If you did not already have a qwiklab account, you will have to create the account using the email used for the registering in the institute.

If you are a walk-in, please have your local host site POC send your email and site name to
