Generally speaking, LCCs and Convolution are basic image-based information processing steps that find numerous a… text/html 2012-10-06T00:02:48+02:00 http://autogpu.ee.auth.gr/doku.php?id=flcc_copyright&rev=1349470968&do=diff Copyright Copyright 2010 George Papamakarios, George Rizos, Nikos Pitsianis and Xiaobai Sun.

It is developed in CUDA targeting NVIDIA's CUDA enabled GPUs. K-means is a basic clustering algorithm widely used for clustering large amounts of data. It has been used in numerous applications in areas such as statistical machine learning, data mining, image processing and many more. However the computation has always been considered of high arithm… text/html 2012-10-07T22:22:32+02:00 http://autogpu.ee.auth.gr/doku.php?id=n-body-bench&rev=1349637752&do=diff Introduction The purpose of the thesis is to provide a description of the “n-body problem”, both gravitational and electrostatic , and also, to provide a description of the solving methods available. The thesis analyzes various versions of the Tree Code algrithm, by Appel, Jernigan and Porter and Barnes and Hut.Furthermore complexity analysis and error analysis are provided, as well as an examination and description of the data structures the algorithms use.The algorithms are compared on the… text/html 2013-04-05T01:33:45+02:00 http://autogpu.ee.auth.gr/doku.php?id=news&rev=1365114825&do=diff 2013 * April 4: FLCC Version 1.5 released (go here for details) 2012 * September 30: FLCC Version 1.4 released (go here for details) 2011 * December 11: FLCC Version 1.3 released (go here for details) * July 15: FLCC Version 1.2 released (go here for details) text/html 2014-02-26T10:24:37+02:00 http://autogpu.ee.auth.gr/doku.php?id=people&rev=1393403077&do=diff Nikos P.
