Online training course: "Introduction to Kebnekaise", 21 September 2023

HPC2N is offering an ONLINE training course "Introduction to Kebnekaise". It will be given on 2023-09-21, 09:00 - 17:00.

We begin with a short OPTIONAL 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.

Then, we continue with an introduction to HPC and HPC2N, before moving to a walk-through of the Kebnekaise system, including the GPUs. In the afternoon we go through the module system and take a look at how to submit jobs. During the hands-on you will get the opportunity to try loading modules, compile a program, and submit a job to the Kebnekaise cluster.

Eligibility: since Kebnekaise is no longer a NAISS cluster, this course in only available to local users. This is defined as users who are current or future members of projects with a PI affiliated with HPC2N's partner sites (UmU, SLU, LTU, MIUN, IRF). Participation is free.

ENCCS training events

Julia for High Performance Scientific Computing, online, October 10-13,  9:00-12:00 CEST

Julia is a modern high-level programming language that is fast (on par with traditional HPC languages like Fortran and C) and relatively easy to write like Python or Matlab. It thus solves the “two-language problem”, i.e. when prototype code in a high-level language needs to be combined with or rewritten in a lower-level language to improve performance.

ENCCS is organising two back-to-back online workshops on Julia in October - this one is about high-performance scientific computing, while the other on October 2-5 will deal with high performance data analysis and machine learning. The first day of both workshops will be an introduction to the Julia language.

After attending the workshop you will:

• Be comfortable with Julia’s syntax, in-built package manager, and development tools.
• Understand core language features like its type system, multiple dispatch, and composability.
• Be able to write your own Julia packages from scratch.
• Know how to write highly performant Julia code.
• Have an overview of Julia’s parallelization and GPU-porting strategies.
• Be able to write parallel and GPU-ported Julia code which runs efficiently on an HPC system.

For further information and registration, please visit the Julia for HPC workshop page (ENCCS).

Quantum Autumn School, Gothenburg, October 25-27, 9:00-17:00

Recent developments in quantum technology are bringing the world closer to a new technological revolution – the advent of usable quantum computers able to provide enormous acceleration to important computational tasks. In coming years, quantum computing is expected to have a significant impact on many areas of research that can utilise computational modelling. ENCCS is now again joining forces with the Wallenberg Centre of Quantum Technologies (WACQT) and the Nordic/Baltic NordIQuEst project to deliver a three-day autumn school covering the fundamentals of quantum computing.

The main attendance mode of the autumn school will be on-site at Chalmers University of Technology in Gothenburg. On-site participants will also be treated to social and networking events and a guided tour to see the QAL9000 quantum computer at Chalmers. However, seminars and hands-on sessions will also be broadcast live for online participants who will be able to participate actively in the school through live Q&A and chat.

The school will cover:

• Introduction to key concepts: quantum states, qubits, quantum algorithms
• Overview of the main QC hardware approaches.
• Overview of the QC software stack.
• Integration of QC with classical computing: hybrid classical/quantum algorithms and HPC-QC systems.
• QC programming in high-level languages for use cases in optimisation, finance, life science and quantum chemistry.

Morning lectures will be combined with afternoon hands-on sessions where participants learn to use high-level QC programming languages using either simulators or real quantum computers.

For further information and registration, please visit the quantum autumn school page (ENCCS).
