This course will familiarize the student with the basics of accessing and interacting with high-performance computers using the GNU/Linux operating system’s command line. Topics include: a brief overview of Linux, the command shell, navigating the file system, basic commands, shell redirection, permissions, processes, and the command environment. Through hands-on experience, students will become familiar with the Linux command-line interface to high-performance computer systems, or other Linux systems for manipulating and analyzing data.

In order to participate successfully in the workshop exercises, you must have a Flux user account, a Flux allocation (one is created for each workshop), and an MToken. The user account allows you to log in to the cluster, create, compile, and test applications, and prepare Flux jobs for submission. The allocation allows you to submit those jobs, executing those applications in parallel on the cluster and charging their resource use against the allocation. A token is required to authenticate you to the cluster.
A single Flux user account can be used to prepare and submit jobs using various allocations. If you already already possess a user account, you can use it for this course, you can skip to “Flux allocation” below. If not, please visit https://arc-ts.umich.edu/fluxform to obtain one. A user account is free to members of the University community. Please note that obtaining an account requires human processing, so be sure to do this at least two business days before class begins.
We create an allocation for the workshop so you can run jobs on the cluster during the workshop and for one day after for those who would like additional practice. The workshop allocation is quite limited and is intended only to run examples to help you cement the details of job submission and management. If you already have an existing Flux allocation, you can use that, though if there are any issues with that allocation, we will ask you to use the workshop allocation.
An MToken (hardware or software) is required to log in to the cluster. When logging in, you will need to give both the passcode it displays at time of login as well as your UMICH password in order to authenticate. If you already have an MToken, you can ignore the rest of this section.
If you need an MToken, follow the instructions at Obtaining, Activating, and Using an MToken.
Activate and test your MToken before you come to class.
