Efficient Computing in Julia

eScience Center Digital Skills Programme

This workshop teaches you how to write efficient code in Julia, single-threaded, multi-threaded and on the GPU.

Netherlands eScience Center

The workshop will take place at Science Park 402, 1098 XH Amsterdam. Please note that lunch and drinks at the end of the workshop are included.The Julia programming language is getting more and more popular as a language for data analysis, modelling, and optimization problems. It promises the ease of Python or R with a run-time efficiency closer to C or Fortran. Julia is also a more modern language with a packaging ecosystem that makes packages easier to install and maintain. A programmer that is familiar with Python, R or Matlab should have little problem getting up to speed with the basics of Julia. However, to really obtain the promised near native run-time efficiency is a different skill altogether.This workshop is aimed at researchers and research software engineers who are already experienced in another programming language than Julia. We will make participants aware of the major techniques and pitfalls when it comes to writing performant Julia.We will work hands-on with real-world examples to explore concepts in the Julia language, focusing on differences with other languages. After the first day, you will be familiar with the basic constructs of the language, some popular libraries, and its package manager, including unit testing and documentation.The second day we will dive deeper in making Julia code fast to run. We’ll see how to benchmark and profile code and find out what is fast and slow. This means getting to grips with Julia’s type system and its compilation strategy. We will close the day with parallel programming and using the GPU to make our code even faster.The workshop is based on the teaching style of the Carpentries, and learners will follow along while the instructors write the code on screen.
