Training

HPC@LSU offers a sequence of tutorials every semester.

1. February 08,2023: Basic Shell Scripting

TopicBasic Shell Scripting
DateFebruary 08,2023
Time9:00 AM - 11:00 AM
PlaceZoom Online
DescriptionFor anyone who works in a Linux/Unix environment, a working knowledge of shell scripting is essential and will boost their efficiency and productivity tremendously. For this tutorial, we will focus on bash as it is one of the most popular shells. This tutorial will include topics such as creating simple bash scripts, flow control, command line arguments, regex, grep, awk and sed. This is a practical tutorial, so we will provide examples and/or hands-on exercises for most of the covered materials.

Prerequisites
  • LONI or LSU HPC account
  • Familiarity with Linux/Unix
  • Editors such as vi or emacs
  • SSH client such as Putty for Windows

2. February 15,2023: Introduction to GNU Parallel

TopicIntroduction to GNU Parallel
DateFebruary 15,2023
Time9:00 AM - 11:00 AM
PlaceZoom Online
DescriptionIn scientific computation disciplines, such as bioinformatics and computational biology, many computational tools are serial in nature. To effectively run many serial jobs simultaneously on multi-core HPC platform can be challenging. GNU Parallel is an easy to use and also powerful tool for executing commands/tasks in parallel on one or multiple host machines. This training will introduce GNU Parallel and its basic features. Hand-on, real-world examples will be demonstrated on how to run different types of massive individual tasks using GNU Parallel.
Prerequisites
  • Basic knowledge of HPC environment and Linux is preferred but not required.

3. March 01,2023: Introduction to Singularity:Creating and Running Containers on HPC

TopicIntroduction to Singularity:Creating and Running Containers on HPC
DateMarch 01,2023
Time9:00 AM - 11:00 AM
PlaceZoom Online
DescriptionContainers such as Singularity allow users to pack an application and all of its dependencies, including the operation system, into a single image, which makes the application more portable, shareable, and reproducible. For instance, one user can create in his/her own HPC environment a Singularity image for a complex workflow with many software components and their dependencies, then share it with other users, who can run the workflow on other HPC systems, independent of the environment as along as Singularity is supported. In this tutorial, we will show how to build Singularity images and run them on the LSU/LONI HPC clusters.

4. March 08,2023: Open OnDemand: Interactive HPC via the Web

TopicOpen OnDemand: Interactive HPC via the Web
DateMarch 08,2023
Time9:00 AM - 11:00 AM
PlaceZoom Online
DescriptionThis training will provide an introduction to Open OnDemand, a browser based tool now available to all LSU HPC users on campus. Open OnDemand requires only a web browser (no plug-ins) and an LSU HPC account. It features a file browser, command line shell access, job management, and access to interactive Jupyter notebooks and RStudio servers running interactively on SuperMIC's compute nodes. This training will feature an overview of Open OnDemand, and a demonstration of all it's features, including Jupyter Notebook and RStudio.

Prerequisites
  • LSU HPC account
  • Some knowledge of using HPC is assumed but not required

5. March 22,2023: Introduction to Python

TopicIntroduction to Python
DateMarch 22,2023
Time9:00 AM - 11:00 AM
PlaceZoom Online
DescriptionPython is a high-level programming language, easy to learn yet extremely powerful. This training will provide an introduction to programming in Python. The subjects include basic Python syntax, Python classes used in object-oriented programming. Basic Python modules for scientific computing and plotting will also be introduced. During the training, simple Python programs will be provided for demonstration.

Prerequisites
  • Basic understanding of a programming language is assumed but not required.

6. March 29,2023: Managing Software Packages with Conda Virtual Environment

TopicManaging Software Packages with Conda Virtual Environment
DateMarch 29,2023
Time9:00 AM - 11:00 AM
PlaceZoom Online
DescriptionConda is an open source package management system and environment management system that runs on Windows, macOS, and Linux. Conda quickly installs, runs and updates packages and their dependencies. Conda easily creates, saves, loads and switches between environments on your computer. It was initially created for Python programs, but now becomes a powerful tool to manage software packages in genenral.

For HPC users, conda is especially useful to install and manage software packages in user environments without the need of super user permissions. It is also good at installing dependencies that are otherwise a hassle to compile manually on clusters, and allows easy shared access amount group members.

This training will feature basic usages of conda and virtual environment on LSU and LONI HPC clusters, as well as some frequently used advanced features.

Prerequisites
  • Basic understanding of the shell commands and python programming language is assumed but not required.
