Managing Your Account

Once your account is set up, you will receive a welcome letter from us containing your username and default password, which will allow you to register your ARMSTRONG account.

The ARMSTRONG portal provides many services to OSC users, including:

  • password/shell maintenance
  • resource unit usage and the project's RU balance
  • updating outside funding and publications that acknowledge OSC
  • research opportunities and venues for connecting with other users
  • systems and training notices

Before your project balance reaches 0 RUs, the Principal Investigator should refer to https://www.osc.edu/supercomputing/additional_resources . Proposals will be peer reviewed

 

Getting Connected

There are two ways to connect to our systems. The traditional way will require you to install some software locally on your machine, including an SSH client, SFTP client, and optionally an X Windows server. The alternative is to use our zero-client web portal, OnDemand.

HPC Basics

Overview

Using the HPC or “supercomputer” is a little different from running programs on your desktop. When you login you’ll be connected to one of the system’s “login nodes”. These nodes serve as a staging area for you to marshal your data and submit jobs to the batch scheduler. Your job will then wait in a queue along with other researchers' jobs. Once the resources it requires become available, the batch scheduler will then run your job on a subset of our hundreds of “compute nodes”. You can see the overall structure in the diagram below.
