Submissions for NSDI '08 are closed. Authors who have submitted abstracts should now submit the corresponding full paper, using their login and password. Your uploaded file should contain a full paper in PDF or PostScript format. PDF PDF appears to be the safest and most portable way of moving text page images from one place to another. You should format your original page for US Letter size. PDF files are detected by examining the first PDF characters of the file, if they are '%PDF' then file is assumed to be in PDF format. PostScript PostScript, these days, is often very non-portable. You should take care to format the page for US Letter size, and ensure that all the portability switches are turned on if you are using a Windows platform.
