Slurm, which stands for Simple Linux Utility for Resource Management, is a widely used open-source HPC resource management and scheduling system that originated at Lawrence Livermore National Laboratory.
It is decided that OSC will be implementing Slurm for job scheduling and resource management, to replace the Torque resource manager and Moab scheduling system that it currently uses, over the course of 2020.
An ACL (access control list) is a list of permissions associated with a file or directory. These permissions allow you to restrict access to a certain file or directory by user or group.
checkgpu is a command developed at OSC for use on OSC’s systems to report information regarding the usage of OSC’s GPU nodes. It reports various information on the usage and availability of the GPU nodes.
In March 2020, OSC expanded the existing project and scratch storage filesystems by 8.6 petabytes. Adding the existing storage capacity at OSC, this brings the total storage capacity of OSC to ~14 petabytes.
OSCprojects is a command developed at OSC for use on OSC's systems and is used to view your logged in accounts project information.
OSCgetent is a command developed at OSC for use on OSC's systems and is similar to the standard getent command. It lets one view group information.
OSCusage is command developed at OSC for use on OSC's systems. It allows for a user to see information on their project's usage, including different users and their jobs.
It is strongly suggested to consider the available per-core memory when users request OSC resources for their jobs.
On Owens, it equates to 4315MB/core or 118GB/node for the regular dense compute node.
OSCfinger is a command developed at OSC for use on OSC's systems and is similar to the standard finger command. It allows various account information to be viewed.
This page includes a summary of differences to keep in mind when migrating jobs from other clusters to Pitzer.
