Getting Started on Polaris

Logging Into Polaris

To log into Polaris:

ssh <username>
Then, type in the password from your CRYPTOCard/MobilePASS+ token.

Hardware Overview

An overview of the Polaris system including details on the compute node architecture is available on the Machine Overview page.

Compiling Applications

Users are encouraged to read through the Compiling and Linking Overview page and corresponding pages depending on the target compiler and programming model.

Accessing Additional Software

In addition to the Cray PE, ALCF installs software in /soft which can be accessed via module commands by altering your $MODULEPATH:

module use /soft/modulefiles
The available software can then be queried with module avail.

Additionally, a suite of software packages are provided via Spack deployments, detailed on the Spack PE page.

Submitting and Running Jobs

Users are encouraged to read through the Running Jobs with PBS at the ALCF page for information on using the PBS scheduler and preparing job submission scripts. Some example job submission scripts are available on the Example Job Scripts page as well.

export ftp_proxy=""
export no_proxy="admin,polaris-adminvm-01,localhost,*,polaris-*,*,*"
