HOWTO: Reduce Disk Space Usage

This HOWTO will demonstrate how to lower ones' disk space usage. The following procedures can be applied to all of OSC's file systems.

We recommend users regularly check their data usage and clean out old data that is no longer needed.

Users who need assistance lowering their data usage can contact OSC Help.

HOWTO: Install Python packages from source

HOWTO: Locally Installing Software

Sometimes the best way to get access to a piece of software on the HPC systems is to install it yourself as a "local install". This document will walk you through the OSC-recommended procedure for maintaining local installs in your home directory or project space. The majority of this document describes the process of "manually" building and installing your software. We also show a partially automated approach through the use of a bash script in the Install Script section near the end.

HOWTO: Install your own Perl modules

While we provide a number of Perl modules, you may need a module we do not provide. If it is a commonly used module, or one that is particularly difficult to compile, you can contact OSC Help for assistance, but we have provided an example below showing how to build and install your own Perl modules. Note, these instructions use "bash" shell syntax; this is our default shell, but if you are using something else (csh, tcsh, etc), some of the syntax may be different.

HOWTO: Use ulimit command to set soft limits

This document shows you how to set soft limits using the ulimit command.

The ulimit command sets or reports user process resource limits. The default limits are defined and applied when a new user is added to the system. Limits are categorized as either soft or hard. With the ulimit command, you can change your soft limits for the current shell environment, up to the maximum set by the hard limits. You must have root user authority to change resource hard limits.
