Containers in Supercomputing Environment

Teacher Laxmana Yetukuri

Containers in Supercomputing Environment

Scientific tools often require installing different dependencies in a controlled environment. Containers allow you to logically package your application together with libraries and other dependencies, providing isolated environments for running your software services. Containerized applications can be run in an isolated runtime environment independent of the actual environment (e.g., private data center, the public cloud, or even a developer’s personal laptop) in which the applications are running in. These are recently gaining popularity as a standard way to distribute, deploy, and run services by developers and system administrators. This course will introduce the basic concepts of containers and their deployment in supercomputing environment at CSC.Course Program:6th, June 2023 - Brief Introduction to CSC HPC systems - CSC- specific containers (e.g., Tykky) - Introduction to Singularity/Apptainer 7th, June 2023- Building Apptainer container images - Introduction to Docker containers 8th, June 2023- Conversion of Docker images to Apptainer images on CSC systems - R and Jupyter notebooks as containers - High-throughput computing with containers

Linux-2: Advanced command line use and Bash programming, study group autumn 2023

Teacher Thomas Zwinger

Linux-2: Advanced command line use and Bash programming, study group autumn 2023

CSC training course for advanced command line use, common GNU/Unix tools, and Bash programming.To whom: You are already using Linux command line and writing Bash scripts, but would like to know better how do these actually work. After this course you should be able to use command line more efficiently, and write more elegant shell scripts, and fix the misbehaving ones.The course is organised as an intensive on-line study group. Short lecture type material and exercises contain questions that the students first study independently or in small groups, and are then discussed in the course forum and in on-line meetings.

Introduction to Linux online

Teacher Thomas Zwinger

Introduction to Linux online

This course will go through the very basics of Linux/Unix utilization, mainly through the shell (text-based user interface). We do not expect any previous knowledge of the topic, just basic skills to operate any computer. No programming knowledge is expected. At the end of this course the student should survive in a complete shell-based Linux/Unix environment, like one finds when logging into large computing serves, such as those at CSC.Mainly driven by the current situation, this is a complete online course. It is split into a preparatory phase of one week where the students should read some basic background and install a virtual machine containing the Linux system we use during the course. The second week then will be a mixture of online studies and interactive work.

Introduction to LINUX

Teacher Thomas Zwinger

Introduction to LINUX

This two day course will cover the very basics of Unix/Linux. No previous knowledge about these operating systems is expected, as the course serves as an introduction to those who are completely new to Linux. Both days have extended hands-on exercises.The course will give the participant the basic knowledge and skills to use the Unix shell. How to navigate around, copy files and launch applications. In addition to being useful on CSC's servers, basic unix skills may come in handy elsewhere too, and knowing the basics makes later self study much easier. The hands-on exercises also will include a demonstration on how to set up one's own Linux system.

CSC Prerequisite minicourse

CSC Prerequisite minicourse

To access and use supercomputers like Puhti and Mahti, you need to be able to work with text-based Command Line Interface (CLI). This is a new challenge to many people who are more used to using Graphical User Interfaces (GUI) in Windows and macOS. This course provides users with "basic command line skills" that are a prerequisite in many CSC courses. To make sure you get the most out of the other courses, please go through this material and skill tests first. Happy journey on the command line!

MBDP-108 Advanced Linux

Teacher Thomas Zwinger

MBDP-108 Advanced Linux

This course builds upon the earlier Introduction to Linux course. We expect people to be familiar with the concepts of file-system related (ls, rm, mkdir, cd ...) commands and have a basic knowledge about the shell. At the end of the course the students should be able to build workflows inside bash and to use POSIX text utilities to search, reorder and modify larger data and files. In other words, to use the shell in production related to scientific computing.Program, December 16th 09:00 – 09:30 Morning coffee & registration 09:30 – 09:45 Introduction to the course 09:45 – 10:45 Recapping Introduction to Linux course 10:45 – 11:30 Working with the Bash shell, pt.
