NCSA Blue Waters Computing System
NERSC Computing System
Cori, a Cray XC40, has two types of nodes:
For more info on using Cori, please see: http://www.nersc.gov/users/computational-systems/cori/
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.
ssh from a command prompt to log in to Cori:
Cori uses the SLURM batch system. You can use our job script generator https://my.nersc.gov/script_generator.php 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 https://portal.tacc.utexas.edu/user-guides/stampede2.
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.
