Overview

Learn how to write a portable parallel program that can run on multicore CPUs and accelerators like GPUs and how to apply incremental parallelization strategies using the OpenACC programming model to accelerate an example application that simulates heat distribution across a 2-dimensional metal plate and applying this knowledge to accelerate a mini-application.

Event Format 

The GPU Bootcamp will be hosted online in the Central Africa time zone. All communication will be done through Zoom, Slack and email. 

Prerequisites

Basic experience with C/C++ or Fortran. No GPU programming knowledge is required.
This event has limited capacity, so please make sure that prerequisites are met before applying. You will be receiving an acceptance email with details on how to participate by December 5, 2020.  

Compute Resources

Attendees will be given access to a GPU cluster for the duration of the GPU Bootcamp.
