NIST Gaithersburg

Jan 15-16, 2025

9:00 am - 4:00 pm EST

Instructors: Andrew Reid, Trevor Keller

General Information

Blackbird is a new high-performance research computing cluster at NIST, replacing the capabilities of Raritan and serving the HPC community of practice at NIST. For more information, please visit the RCHPC Discourse site.

This workshop will review shell commands, teach the basics of SSH connections to a remote server, and introduce Slurm, the workload manager used to launch jobs on cluster nodes. Yes, there will be jargon.

The Carpentries project comprises the Software Carpentry, Data Carpentry, Library Carpentry, and HPC Carpentry communities of Instructors, Trainers, Maintainers, helpers, and supporters who share a mission to teach foundational computational and data science skills to researchers.

HPC Carpentry aims to help researchers get their work done in less time and with less pain by teaching them basic cluster computing skills. This hands-on workshop will cover basic concepts and tools, including shell commands, connecting to a remote computer, and interacting with the workload manager. Participants will be encouraged to help one another and to apply what they have learned to their own research problems.

For more information on how we teach and why, please see The Carpentries' paper "Best Practices for Scientific Computing".

This is a pilot workshop, testing out a lesson that is still under development. The lesson authors would appreciate any feedback you can give them about the lesson content and suggestions for how it could be further improved.

Who: This course is aimed at researchers at any career stage. You don't need to have any previous knowledge of the tools that will be presented at the workshop.

Where: Bldg. 224, Rm. B245. Get directions with OpenStreetMap or Google Maps. What3Words location: ///gosh.unfair.ideas.

When: Jan 15-16, 2025; 9:00 am - 4:00 pm EST Add to your Google Calendar.

Requirements: Participants must bring a laptop with a Mac, Linux, or Windows operating system (not a tablet, Chromebook, etc.) that they have administrative privileges on. They should have a few specific software packages installed (listed below).

Accessibility: We are committed to making this workshop accessible to everybody. The workshop organizers have checked that:

We are dedicated to providing a positive and accessible learning environment for all. We do not require participants to provide documentation of disabilities or disclose any unnecessary personal information. However, we do want to help create an inclusive, accessible experience for all participants. We encourage you to share any information that would be helpful to make your Carpentries experience accessible. To request an accommodation for this workshop, please fill out the accommodation request form. If you have questions or need assistance with the accommodation form please email us.

Glosario is a multilingual glossary for computing and data science terms. The glossary helps learners attend workshops and use our lessons to make sense of computational and programming jargon written in English by offering it in their native language. Translating data science terms also provides a teaching tool for Carpentries Instructors to reduce barriers for their learners.

Contact: Please email andrew.reid@nist.gov or trevor.keller@nist.gov for more information.

Roles: To learn more about the roles at the workshop (who will be doing what), refer to our Workshop FAQ.

Who can attend?: This workshop will be conducted in-person on the Gaithersburg campus. There will be a symmetric workshop on the Boulder campus in the not-too-distant future.

This workshop is teaching a lesson in The Carpentries Incubator. Please check the lesson homepage for a list of lesson sections and estimated timings. The lesson taught in this workshop is being piloted and a precise schedule is yet to be established. The workshop will include regular breaks. Please contact the workshop organisers if you would like more information about the planned schedule.

Setup

To participate in an HPC Carpentry workshop, you will need access to software as described below. In addition, you will need an up-to-date web browser.

We maintain a list of common issues that occur during installation as a reference for instructors that may be useful on the Configuration Problems and Solutions wiki page.

The Bash Shell

Bash is a commonly-used shell that gives you the power to do tasks more quickly.

  1. Download the Git for Windows installer.
  2. Run the installer and follow the steps below:
    1. Click on "Next" four times (two times if you've previously installed Git). You don't need to change anything in the Information, location, components, and start menu screens.
    2. From the dropdown menu, "Choosing the default editor used by Git", select "Use the Nano editor by default" (NOTE: you will need to scroll up to find it) and click on "Next".
    3. On the page that says "Adjusting the name of the initial branch in new repositories", ensure that "Let Git decide" is selected. This will ensure the highest level of compatibility for our lessons.
    4. Ensure that "Git from the command line and also from 3rd-party software" is selected and click on "Next". (If you don't do this Git Bash will not work properly, requiring you to remove the Git Bash installation, re-run the installer and to select the "Git from the command line and also from 3rd-party software" option.)
    5. Select "Use bundled OpenSSH".
    6. Ensure that "Use the native Windows Secure Channel Library" is selected and click on "Next".
    7. Ensure that "Checkout Windows-style, commit Unix-style line endings" is selected and click on "Next".
    8. Ensure that "Use Windows' default console window" is selected and click on "Next".
    9. Ensure that "Default (fast-forward or merge) is selected and click "Next"
    10. Ensure that "Git Credential Manager" is selected and click on "Next".
    11. Ensure that "Enable file system caching" is selected and click on "Next".
    12. Click on "Install".
    13. Click on "Finish" or "Next".
  3. If your "HOME" environment variable is not set (or you don't know what this is):
    1. Open command prompt (Open Start Menu then type cmd and press Enter)
    2. Type the following line into the command prompt window exactly as shown:

      setx HOME "%USERPROFILE%"

    3. Press Enter, you should see SUCCESS: Specified value was saved.
    4. Quit command prompt by typing exit then pressing Enter

This will provide you with both Git and Bash in the Git Bash program.

Video Tutorial

The default shell in Mac OS X Ventura and newer versions is Zsh, but Bash is available in all versions, so no need to install anything. You access Bash from the Terminal (found in /Applications/Utilities). See the Git installation video tutorial for an example on how to open the Terminal. You may want to keep Terminal in your dock for this workshop.

To see if your default shell is Bash type echo $SHELL in Terminal and press the Return key. If the message printed does not end with '/bash' then your default is something else, you can change your current shell to Bash by typing bash and then pressing Return. To check your current shell type echo $0 and press Return.

To change your default shell to Bash type chsh -s /bin/bash and press the Return key, then reboot for the change to take effect. To change your default back to Zsh, type chsh -s /bin/zsh, press the Return key and reboot. To check available shells, type cat /etc/shells.

Text Editor

When you're writing code, it's nice to have a text editor that is optimized for writing code, with features like automatic color-coding of key words. The default text editor on macOS and Linux is usually set to Vim, which is not famous for being intuitive. If you accidentally find yourself stuck in it, hit the Esc key, followed by :+Q+! (colon, lower-case 'q', exclamation mark), then hitting Return to return to the shell.

nano is a basic editor and the default that instructors use in the workshop. It is installed along with Git.
