2. Setup Instructions
Please complete these steps before the lessons start at 9:00 !!
Setup instructions:
If you need help with either of the two steps above, please put a red sticky-note at the top of your laptop.
When you are done with both steps, please put a green sticky note at the top of your laptop.

3. Schedule

4. Logistics Location: UNL City Campus Union – Colonial Room (Thursday)
Whittier Hall – room 152 (Friday)
Lunch sponsored by Dell
Name tags, sign-in, coffee
Sticky-notes: Red = need help …… Green = all good
Slides:
Software Carpentry Lessons for Day 1 (with laptop setup instructions)
Etherpad (take notes, ask questions)

5. Introduction to Software Carpentry
Non-profit organization (Greg Wilson)
Mission: Improve basic computing skills and practices of researchers (esp. science, engineering, medicine)
Materials are open-source
Instructors are volunteers

6. Introduction to Software Carpentry
Problem:
Most scientists’ computing skills are self-taught
Learn computing skills on need-to-know basis, limited time
Solution:
2-day “bootcamp”-style workshop / Hands-on training, no slides
Core curriculum:
Unix Shell programming (automating tasks)
Version control (Git and GitHub)
R or Python (building modular, robust code)
Results:
Good programming practices
Reproducable research, time-saving, efficient, re-usable
Today:
1-day bootcamp - only covering Unix Shell programming and Git
For information on upcoming SWC workshops, sign up for the HCC Announce mailing list:

7. Git Software version control tool
Manage files in a project (create repo.)
Save all old revisions
Track changes (who/what/when)
Compare versions
Difficult to overwrite
Collaborate (GitHub: web-hosted repo.)

8. Unix Shell What is the Unix Shell? Why use the Unix Shell? A program
Interact using CLI instead of GUI
Interprets commands, orders computer to execute, and prints out result
Why use the Unix Shell?
Powerful toolset - automate repetative tasks quickly
Easiest way to interact with remote machines
Unix-based operating systems are used on most High Performance Computing (HPC) systems

9. Unix Shell Shell commands can look cryptic at first
Only need to learn about basic commands
We will be using the Bash shell (most popular)

10. Tomorrow HCC specifics: submitting jobs MPI programming primer
Debugging and profiling

12. Coming Soon Attic: $60/TB/year New purchase this fall
256 GB RAM
16-18 core Intel E v4
IB or Omnipath
New purchase following calendar year (?)
