Overview

We currently live in an era where most computers possess multiple computing units, and where parallelization is key.
In particular, GPGPUs (General Purpose Graphical Processing Units) are built for massive parallelism and they have recently risen to prominence as they are now used for many scientific tasks, such as physics or biological simulations, statistical inference or machine learning.

In this crash course we will focus on CUDA as well as several CUDA-based API, including openMP GPU offloading and python APIs. Through concrete examples we will describe the principles at the core of a successful parallelization attempt.

Audience

This course is intended for programmers and computational biologists who want to take their first steps with GPU programming.

We will assume no previous knowledge of GPU programming, CUDA, or parallelization techniques, but we require that the participant be proficient in at least one language among python or C++.

Learning outcomes

By the end of the course, the participant will be able to:
* identify good candidates tasks for GPU acceleration
* understand the structure of a GPU, including memory handling
* perform some computations on a GPU, using either python or C++
* manage memory transfers to the GPU for better performances
* evaluate their GPU code using profiling

Prerequisites

Knowledge / competencies

Participants should be comfortable working in a Linux/UNIX environment and have some basic experience in programming.
Some knowledge of C/C++, Fortran or Python is necessary.

Technical

You are required to work on your own laptop with an Internet connection.
The computer you use for the practicals should be the same as the one you use to connect to the course zoom room (in order for us to help you debug your code during practicals).
