Course syllabus

• This is Tracks course. In this course, the students will learn how to write a simple CFD, FEM code, a Poisson solver or a wave propagation solver. The code should run entirely or partly on the GPU using CUDA. MSc and PhD students at Chalmers are welcome. Study period 2, 2023.
• The course does not belong to a specific Master programme but it is a cross disciplinary course.
• What is a Tracks course?
• The course fulfils sustainable development goals (SDGs) Goal 9: Industry, Innovation and Infrastructure

Nvidia, CUDA, GPU

• Nvidia has developed a programming interface for GPUs called CUDA
• CUDA In Action - Research & Apps
• Nvidia is very active in updating CUDA
• Many companies, such as Volvo Group, Volvo Cars use Nvidia Graphic Cards which are programmed in CUDA.
• Chalmers hosts a national GPU cluster

Course content

• Introduction lectures first week on CUDA programming including two mini-workshops.
• Project.
  • the student groups write a simple CFD/FEM code or Poisson solver or wave propagation solver in CUDA. Ideally, each group includes students with knowledge in CFD, FEM, Poisson equation or wave propagation and CUDA.
  • Here are examples of Python codes for Poisson, LaPlace, linear and non-linear convection, Burger's equation etc
  • Here's an example of a simple Poisson solver (by lada) which can be used for working on Poisson solvers
  • Here's an example of a finite volume code written in CUDU (by lada)
  • Here's an example of a student reports from the Track course 2022
  • Students who choose to do a CFD project may start with a CFD Python code (by lada) with a turbulence model or a simpler Navier-Stokes code
  • profiling (GPU time, uploading/downloading data to/from the GPU etc)
  • Written and oral presentation of the project

Learning outcomes

General learning outcomes are found in the course description of TRA105 - Tracks advanced 1

Detailed learning outcomes

• be able to programme numerical solvers in Python
• be able to programme in CUDA
• be able to profile the programme

Course PM

The first lecture (including mini workshop) will take place on Thursday 2 Nov at 13.00-15.00 in Room SB3-L113. There will be one more lecture 7 Nov at 13.00-15.00 in SB2-L408. The remaining of the course will mainly be project work and project meetings (once a week). The times for the meetings will be determined by each project group.

Please bring a lap-top to the first lecture. It is not necessary that your lap-top has a Nvidia graphics card.

A large part of the course will consist of a programming project. It should be on either FEM, CFD or solving a Poisson equation or the wave propagation equation. Please send an Email to lada@chalmers.se giving your preference. We will then form groups of 3-4 students.

We will arrange a mid-term meeting where the project groups will give a short presentation of the status of their project

At the end of the course (probably in the exam week), we will organize a workshop where all project groups will present their work. The project groups should also submit a report.
