For the past few years, the demand for more realistic games in an ever growing market has lead GPU manufactures to produce high end graphics cards that are able to render complex scenes at very fast frame rates. As graphics problems are embarrassingly parallel in nature, GPUs have been designed as massively parallel architectures. Furthermore, to deal… text/html 2008-06-15T19:14:59+10:00 zein http://cs.anu.edu.au/people/Ahmed.ElZein/doku.php?id=start&rev=1213521299&do=diff Welcome to my ANU website. I joined the ANU in March 2007 as a Masters by research student at the Department Of Computer Science (DCS). I am looking into running Statistical Machine Learning (SML) applications on Graphical Processing Units (GPU). More about Me
