2-3:30pm, Room 1.218, University Place.
Roko Grubisic, ARM: "Embedded Computer Graphics and ARM Mali GPUs"
With the ever increasing complexity of mobile graphics content, today's embedded GPUs have to support a rich feature set and meet performance previously only available to desktop GPUs, but at only a fraction of power and area cost. The aim of this talk is to give a broad overview of the current state of mobile graphics running OpenGL ES 2.0 content and the expected visual computing revolution as new APIs, such as OpenCL and DirectX 11, arrive on our smartphones. We will introduce the ARM Mali family of embedded GPUs and discuss the possible advantages of using embedded GPUs for teaching computer graphics to students.
Roko Grubisic is a graphics hardware engineer at the Media Processing Division of ARM Ltd. He got his degree from the Faculty of Electrical Engineering and Computing (FER) at the University of Zagreb, Croatia. After a year as a research assistant at the Department of Electronics, Microelectronics, Computer and Intelligent Systems at the same school, he joined ARM where he is currently working on design and verification of the next generation GPUs.
Phil Couch, Health Sciences: "Real-Time Healthcare Policy Simulation on a GPU"
Phil was ill so this talk will be re-arranged
The high throughput nature of GPUs and the recent development of general purpose APIs to program GPU devices has lead to their application in a number of scientific HPC domains. IMPACT2 is a project for implementing computer systems that allow the development of healthcare policy models and simulations based on these models to be executed and analysed in real-time. The system allows users to calibrate their models against data from observational studies using algorithms that often require the execution of many hundreds of simulations. This is a time consuming process on many conventional CPU based systems, resulting in a loss of interactivity and model exploration. Here we discuss our use of OpenCL to accelerate simulations through their execution on GPUs, presenting details of optimisations and performance.
Dr Philip Couch is a software engineer in Health Sciences at the University of Manchester. He has a chemical physics and informatics background and has gained a BSc and PhD in Chemistry from the University of Nottingham. Philip worked in Nottingham as a research associate in astronomy before moving to the Science and Technology Facilities Council, where he worked on the development of Semantic Web standards and tools for scientists. Philip currently works as part of the Northwest Institute for BioHealth Informatics, engineering computer systems to allow collaborative development and use of healthcare policy models.
