HPC2N
High Performance Computing Center North
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 event is free and will be online. The talk will be recorded.
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.

The aim of the course is to let participants learn how to use NAMD to set up basic molecular dynamics simulations, and to understand typical NAMD input and output files.
OpenMP provides an efficient method to write parallel programs in C, C++ and Fortran. OpenMP programs are suitable for execution on shared memory architectures such as modern multi core systems or a single compute node of the HPC clusters deployed by Lunarc or HPC2N, and within SNIC.
HPC2N is offering an ONLINE introduction course to HPC2N and Kebnekaise.
We begin with a short (optional) introduction to Linux, then continue with an introduction to HPC, HPC2N, and a walkthrough of Kebnekaise, including the GPUs and the KNLs. We then look at the module system and loading the software you need, and how to submit jobs through the batch system.
There will be hands-ons as a part of the course, where the participants get the opportunity to load modules, compile programs, and submit jobs to the Kebnekaise system.
The aim of this ONLINE course is to give an intro to classical Molecular Dynamics (MD) simulations and the combined Quantum Mechanical and Molecular Mechanics (QM/MM) simulations. We will start from scratch by setting a MD simulation, in the first half-day of the course, and then use this system to setup a QM/MM simulation. Regarding the software, we will use VMD, NAMD, ORCA, and GAUSSIAN for the full QM/MM protocol. We will also provide users with a set of best practices to improve the performance of their simulations.
This four-day course will be an introduction to version control, with a focus on Git. It is a SNIC/PRACE course and will be given online, through Zoom.
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.
Message Passing is presently the most widely deployed programming model in massively parallel high performance computing. Message passing is suitable for programming a wide range of current computer architectures, ranging from multi-core desk top equipment to the fastest HPC systems in the world, offering several hundred thousand processing elements.
Organizers: BioExcel Centre of Excellence, Sweden; STFC Daresbury Laboratory, UK; NCSA, Bulgaria; Sofia University, Bulgaria.
The school will be held virtually.
Date: 20-24 September 2021 via Zoom.
