Computing Systems

NCSA Blue Waters Computing System

NERSC Computing System

Cori, a Cray XC40, has two types of nodes:
  • 2388 nodes, each with two 16-core Haswell Intel processors and 128GB DDR4 memory, and
  • 9688 nodes, each with a 68-core Intel 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 Cori:

Running Jobs
Cori uses 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 either specify it in your batch job script:
or on the command line when you submit your job:
sbatch --reservation=NAMEOFRESERVATION ./mybatchscript

Information about the Stampede2 system can be found at

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 --reservation=S2PI 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.
