DeapSECURE module 1: Introduction to HPC

This is the first module of ODU’s DeapSECURE cyberinfrastructure training. This module contains the introduction to High-Performance Computing (HPC) clusters, complemented with many hands-on exercises. Our final goal in this module is to perform basic analysis on a massive set of spam emails.

Contents & Roadmap

  1. Introduction to HPC–the background
  2. Accessing an HPC system–hands-on on Turing cluster
  3. UNIX shell interaction
  4. Text processing with UNIX shell
  5. Speeding up massive data processing: an example of SPAM email analysis
  6. Going forward

Where are we going?

First, we introduce what an HPC is, then how to access an HPC system (ODU Turing cluster). Next, we will present a crash course, or refresher, on UNIX shell. We will use the UNIX shell knowledge to write a simple pipeline to process a very large number of spam emails and obtain some statistical knowledge about them.


  • Basic computer interactions, students should know how to interact with a computer using a keyborad.
  • Basic concepts such as directories, files, and paths.
  • Basic text editing skills. Students should know how to input text, issue commands…
