CUDA is the standard API for code development targeting NVIDIA GPUs and a number of impressive examples have already been given in diverse areas from particle physics to computational biology. CUDA allows simple extensions of standard C/C++/Fortran code with GPU-specific functions. In this way thousands of cores available on the GPU can be leveraged to work in parallel and thus carry out significant fractions of the computational workload on the device rather than the CPU. There is also a vast set of auxiliary tools available to the developer including libraries, code templates, building blocks, analysis tools, developmental frameworks and in general a vivid community making up the CUDA Developer Zone. It is often for this multifaceted support environment that the interested beginner is feeling overwhelmed and unsettled about which particular first steps should best be taken to gain a straightforward introduction into the subject. For exactly this reason the present course is offering a systematic step-by-step introduction into GPU computing from the perspective of the newcomer. Basic design principles will be established, central programming techniques acquired and a number of state-of-the-art workflows examined that efficiently employ the GPU and are frequently used in scientific computing.

This course provides lectures, demos, and hands-on labs.

Content Levels: Beginners = 0:00h (0%) + Intermediate = 13:00h (100%) + Advanced = 0:00h (0%)

This course is a PRACE training event. It is organized by the VSC Research Center, TU Wien.

Agenda & Content

1st day – 24 October 2022

  • Basic design principles, getting started with simple CUDA routines, mastering the CUDA environment;
  • Memory hierarchy with a focus on CUDA managed unified memory;
  • Practical exercise: all the pitfalls one can run into when porting a dummy code to CUDA.

14:00 - 17:00    lectures and hands-on labs (with breaks: 15:20-15:35)

2nd day – 25 October 2022

  • Selected examples to demonstrate CUDA capabilities and GPU operation, e.g., bandwidthTest, simpleAssert, simpleStreams, etc.;
  • CUDA libraries, CUBLAS, CUSolver, considering numerical precision, gaining insight into the runtime;
  • Practical exercise: CUDA in everyday life (of a scientist).

Course Format:

This course will be delivered as a LIVE ONLINE COURSE (using Zoom) for remote participation.


We welcome a basic scientific mindset, curiosity, a keen interest in challenging technical innovations and the appreciation of outside-the-box thinking. Participants should be able to work on the Linux command line and have basic knowledge in programming with either C/C++/Fortran.

Hands-on Labs:

The hands-on labs will be done on Austria's brand new flagship supercomputer VSC-5, all participants will get a training user account on VSC-5 for the duration of the course.
Accepted participants will be contacted a few days before the course and asked to do a short PRE-ASSIGNMENT that has to be completed before the course starts.

Language: English
