However they are often the key bottle neck<br>of the application when one tries to use a very large number of processors.<br><br>We will discuss key parallelisation strategies for parallel FFTs and<br>will show how they perform across a range of HPC platforms. We will<br>discuss how the placement of the task onto the machine and the<br>dimensions of the chosen processor grid can affect the performance of<br>the FFT.<br><br>#### end abstract ###<br><br>Technical details:<br><br>Windows XP, Vista, Windows 7 with internet explorer (NO OTHER BROWSER<br>WORKS PROPERLY).<br><br>- Accessing via web browser (requires internet explorer 7 and Quicktime):<br>1) go to the url: <a href="http://video-conference.bsc.es">http://video-conference.bsc.es</a><br>2) Write the name you want to be identified in the videoconference<br>3) Reunion ID: 6001.<br><br>Please note that you need to install the videconference software in advance and therefore we would STRONGLY recommend that you do this at the earliest opportunity as it may take a little time and may also involve logging on as administrator.<br><br>Catherine<br><br>-- <br>Catherine Inglis<br>EPCC, The University of Edinburgh<br>James Clerk Maxwell Building<br>The King's Buildings<br>Edinburgh EH9 3JZ (UK)<br><br>Email: <a href="mailto:c.inglis@epcc.ed.ac.uk">c.inglis@epcc.ed.ac.uk</a><br>Tel: +44 131 651 3578<br>Fax: +44 131 650 6555<br><br>HPC-Europa visitor programme at EPCC: <a href="http://www.epcc.ed.ac.uk/europa/">http://www.epcc.ed.ac.uk/europa/</a><br>HPC-Europa consortium homepage: <a href="http://www.hpc-europa.org/">http://www.hpc-europa.org/</a><br><br>The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.<br><br></div></blockquote></div><br></div></body></html>
