R in an HPC environment

Introduction to Git

The course will be an introduction to version control, with a strong focus on Git.

Some of the main concepts, like repositories, commits, trees, branches, and merges will be covered, as will many of the basic commands, like clone, add, push, pull, commit, and fork. We will also go one step beyond the basic concepts and explain the fundamentals of how commits and branches can be manually created by using so-called "plumbing" (low-level) subcommands.

Course: An introduction to parallel programming using Message Passing with MPI, 17-20 October 2022

Julia for High-Performance Scientific Computing

This is a cooperation between HPC2N and ENCCS.

This online workshop will start by briefly covering the basics of Julia’s syntax and features, and then introduce methods and libraries which are useful for writing high-performance code for modern HPC systems. After attending the workshop you will:

Online training workshop - Basic Singularity: Running and building Singularity containers

The online workshop is an introduction to the basic concepts of containerized software environment solution within the Singularity framework https://sylabs.io/singularity/.

This is a cooperation with UPPMAX.

During the workshop you will have the opportunity to follow the interactive guide on how to

UPPMAX and HPC2N are organising a joint ONLINE workshop on how to run Python codes and install additional Python packages on the computer resources provided by these two HPC centres. Participants are encouraged to bring their particular software request for discussion as well.

The goal for the course is that you will be able to:

Course: Introduction to Kebnekaise, 2022-09-15

In this course, we begin with a short introduction to the Linux operating system (OS) that is used on HPC2N's compute cluster, and is the most common OS in HPC clusters. This part is only meant for complete beginners to the Linux operating system, and can be omitted if you are proficient already. See the schedule.

Julia programming: HPC topics

Abstract: In this talk, Kristoffer Carlsson, developer at Julia Computing in Sweden, will talk about the Julia language with particular emphasis on performance in an HPC setting. Topics mentioned will be Julia's compilation pipeline, SIMD, parallelism (shared and distributed memory), among others.

This workshop targets programmers in both academia and industry who already have experience with basic MPI and are ready to take the next step to more advanced usage. Topics which will be covered include communicators, groups, derived data types, one-sided communication, non-blocking collectives and hybrid MPI+threading approaches. Lectures will be interleaved with hands-on exercises. All exercises will be written in C, but the instructors will be able to answer questions about MPI in Fortran and Python.
