Manage users on a project
The PI of a project can manage the users on their projects. Note, that PIs are not automatically added as authorized users under their project(s).
Managing users on the project includes inviting, adding and removing users to the project as well as increasing a user's privileges on a project so that they can assist with the management of it.

This article discusses memory tuning strategies for VASP.
Data Distribution
Typically the first approach for memory sensitive VASP issues is to tweak the data distribution (via NCORE or NPAR). The information at https://www.vasp.at/wiki/index.php/NPAR covers a variety of machines. OSC has fast communications via Infiniband.

This article focuses on debugging strategies for C/C++ codes, but many are applicable to other languages as well.
Rubber Duck Debugging
This approach is a great starting point. Say you have written some code, and it does not do what you expect it to do. You have stared at it for a few minutes, but you cannot seem to spot the problem.
Ascend
Beginning April 30, 2025, all College of Medicine (CoM) projects without a separate MOU established with OSC will be limited to running exclusively on the Ascend cluster, specifically on the nextgen partition. All CoM jobs run on Ascend’s nextgen partition at zero cost, with priority scheduling.
Pitzer
In late 2018, OSC installed 260 Intel® Xeon® 'Skylake' processor-based nodes as the original Pitzer cluster. In September 2020, OSC installed additional 398 Intel® Xeon® 'Cascade Lake' processor-based nodes as part of a Pitzer Expansion cluster.

Owens, Pitzer
This page documents the known issues for migrating jobs from Torque to Slurm.
$PBS_NODEFILE and $SLURM_JOB_NODELIST
Please be aware that $PBS_NODEFILE is a file while $SLURM_JOB_NODELIST is a string variable.
The analog on Slurm to cat $PBS_NODEFILE is srun hostname | sort -n

How to Submit Interactive jobs
There are different ways to submit interactive jobs.
Using sinteractive
You can use the custom tool sinteractive as:
Using ngbrader in Jupyter
Install nbgrader
You can install nbgrader in a notebook:
OSC provide an isolated and custom Jupyter environment for each classroom project that requires Jupyter Notebook or JupyterLab.
