Run matlab code on Derecho

[jiamengl]

Hello, I got a warning email saying that I am running computationally-intensive work on the interactive node (when it should be run on compute nodes instead).
I was attempting to run matlab code on Derecho, which caused this alert.

I am wondering how can I submit my matlab code to a compute node so that I can continue my computation?

Thanks!

Hi! So computationally expensive work like compiling a large code base or running a large python or Matlab script should be done on the compute nodes instead of the login nodes. There are two ways to run a job on the compute nodes. One is to write a submission script and submit it to the queue. You can find info on submit scripts for Cheyenne here, and this applies to Derecho as well: Documentation | ARC NCAR

But probably the easiest thing to do is open an interactive session on a compute node. That makes your shell look like a login node, but you are executing on a compute node. Information on how to do that on Cheyenne (applicable for Derecho as well) is here: Documentation | ARC NCAR

If this advice doesn't work, then this may be a better question for CISL support, which you can find information for how to access here: HPC User Support | Computational and Information Systems Lab
