  • Best Practice for Mobile
    If this doesn’t look familiar, you’re in the wrong conference 1 This section of the course is about the ways that mobile graphics hardware works, and how to work with this hardware to get the best performance. The focus here is on the Vulkan API because the explicit nature exposes the hardware, but the principles apply to other programming models. There are ways of getting better mobile efficiency by reducing what you’re drawing: running at lower frame rate or resolution, only redrawing what and when you need to, etc.; we’ve addressed those in previous years and you can find some content on the course web site, but this time the focus is on high-performance 3D rendering. Those other techniques still apply, but this talk is about how to keep the graphics moving and assuming you’re already doing what you can to reduce your workload. 2 Mobile graphics processing units are usually fundamentally different from classical desktop designs. * Mobile GPUs mostly (but not exclusively) use tiling, desktop GPUs tend to use immediate-mode renderers. * They use system RAM rather than dedicated local memory and a bus connection to the GPU. * They have multiple cores (but not so much hyperthreading), some of which may be optimised for low power rather than performance. * Vulkan and similar APIs make these features more visible to the developer. Here, we’re mostly using Vulkan for examples – but the architectural behaviour applies to other APIs. 3 Let’s start with the tiled renderer. There are many approaches to tiling, even within a company.

  • Load Balancing in a Tiling Rendering Pipeline for a Many-Core CPU
    Master of Science Thesis Lund, spring 2010 Load balancing in a tiling rendering pipeline for a many-core CPU Rasmus Barringer* Engineering Physics, Lund University Supervisor: Tomas Akenine-Möller†, Lund University/Intel Corporation Examiner: Michael Doggett‡, Lund University Abstract A tiling rendering architecture subdivides a computer graphics image into smaller parts to be rendered separately. This approach extracts parallelism since different tiles can be processed independently. It also allows for efficient cache utilization for localized data, such as a tile’s portion of the frame buffer. These are all important properties to allow efficient execution on a highly parallel many-core CPU. This master thesis evaluates the traditional two-stage pipeline, consisting of a front-end and a back-end, and discusses several drawbacks of this approach. In an attempt to remedy these drawbacks, two new schemes are introduced; one that is based on conservative screen-space bounds of geometry and another that splits expensive tiles into smaller sub-tiles. * [email protected] † [email protected] ‡ [email protected] Acknowledgements I would like to thank my supervisor, Tomas Akenine-Möller, for the opp- ortunity to work on this project as well as giving me valuable guidance and supervision along the way. Further thanks goes to the people at Intel for a lot of help and valuable discussions: thanks Jacob, Jon, Petrik and Robert!

Les cartes d'affichage Les cartes graphiques sont des cartes qui s'occupent de communiquer avec l'écran, pour y afficher des images. Au tout début de l'informatique, ces opérations étaient prises en charge par le processeur : celui-ci calculait l'image à afficher à l'écran, et l'envoyait pixel par pixel à l'écran, ceux-ci étant affichés immédiatement après. Cela demandait de synchroniser l'envoi des pixels avec le rafraichissement de l'écran. Pour simplifier la vie des programmeurs, les fabricants de matériel ont inventé des cartes d'affichage, ou cartes vidéo. Avec celles-ci, le processeur calcule l'image à envoyer à l'écran, et la transmet à la carte d'affichage. Celle-ci prend alors en charge son affichage à l'écran, déchargeant le processeur de cette tâche.
