Julia for High-Performance Computing

This 4-day course introduces the Julia programming language as a modern approach to high-performance numerical computing. Starting from the foundations and characteristic language features (e.g. multiple dispatch, type inference) the course will discuss and demonstrate how Julia manages to deliver high performance while also being high-level and dynamic. It will teach participants the necessary language concepts to achieve high performance in Julia and avoid common pitfalls. The course will cover serial and parallel computing (multithreading, distributed computing, MPI) and will provide insights into how to readily offload computations to NVIDIA GPUs.

Hands-on sessions on each day will allow the participants to interactively explore the language and immediately test and apply the discussed concepts.

This course is particularly suitable for students and researchers who are interested in numerical computing and want to learn how to write high-performance code using the Julia programming language.

Learning outcomes

After this course, participants will:

  • have a basic understanding of Julia’s fundamental design and its compilation pipeline
  • know how to write efficient, serial Julia and avoid typical pitfalls
  • know how to profile and benchmark code performance
  • be able to parallelize Julia using multithreading, distributed computing and GPU acceleration
  • be familiar with common (remote) development workflows

Agenda

Local registration starts on first course day at 8:30.

The course runs from Tuesday to Friday. Days start at 9 AM and end at 5 PM (earlier end on Friday).
On the first evening there will be a social event (Stuttgart city tour + dinner). A detailed schedule will
follow.
Among others, the following topics will be covered in the course:


• Julia fundamentals

  • Julia’s type system and multiple dispatch paradigm
  • Code specialization and compilation
  • Development workflow (for HPC clusters)

• Performance programming

  • Type (in-)stability
  • Memory usage optimization
  • Instruction-level parallelism
  • Profiling

• Parallelization

  • Task-based multithreading
  • Basic GPU acceleration
  • Distributed computing (Distributed.jl and MPI.jl)

Course material

Slides, agenda and Jupyter notebooks will be available for all participants on GitHub in time before the course.

Our course fees include coffee breaks (in classroom courses only).

HLRS concept for on-site courses

Besides the content of the training itself, an important aspect of this event is the scientific exchange among the participants. We try to facilitate such communication by

  • a social event on the evening of the first course day,
  • offering common coffee and lunch breaks and
  • working together in groups of two during the exercises.

Lunch Breaks

We plan to have lunch in the unversity's canteen (Mensa Stuttgart-Vaihingen, have a look at their menu online). Two other near possibilities for lunch are on all days:

  • A food truck from 11:00-14:00 in Allmandring 35, approximately 300 m from HLRS,
  • Bakery Sehne, near bus stop "Im Lauchhau", approximately 400 m from HLRS.

We will update this information if opening times etc. change and inform you more precisely before the course starts.
