When it comes to getting their hands on the Grid, SC2003 attendees just can’t get enough of it. Because of the great demand in the session on “How to Build a Grid Service Using the Globus Toolkit(R) 3” scheduled for Monday, Nov. 17, an identical session has been added to the Sunday, Nov. 16, schedule. The tutorials are being offered as part of SC2003, the international conference on high-performance computing and networking. With the theme of "Igniting Innovation," SC2003 will be held November 15-21 in the Phoenix Civic Plaza Convention Center. Advance registration is now open for 30 SC2003 tutorials, on topics ranging from new programming tools to quantum information processing. However, Advance Registration closes Friday, Oct. 10 – after that the fees for the Technical Program registration and Tutorials will go up significantly. Registering in advance for the Technical Program can save up to $170 for ACM and IEEE members and $205 for non-members. Buying a two-day Tutorials passport by Oct. 10 costs just $595 for members or $755 for non-members, while the late-registration cost will be $825 and $1,035 respectively. To qualify for the lower rates, registration and payment must be received by 5 p.m. (Eastern time) Friday, Oct. 10. Online registration (http://www.sc-conference.org/sc2003/registration.html) is available for all aspects of the SC2003 conference. “Although Advance Registration is still open, we looked at the strong demand for the tutorial in building a Grid service and decided to add a second session,” said SC2003 Tutorials Chair Harvey Wasserman of Los Alamos National Laboratory. “This is an intensive hands-on tutorial and we wanted to give as many people as possible an opportunity to participate and still maintain a low student-to-teacher ratio.” Seating is limited for each of the tutorials, which are either half-day or full-day sessions, depending on the topic. A full list of tutorials can be found at http://www.sc-conference.org/sc2003/tech_tutorials.php . Information about registration – either for a single session or a one-day or two-day passport, is at http://www.sc-conference.org/sc2003/registration.html . Questions about the tutorial program should be addressed to tutorials03@sc-conference.org. SC2003 continues the 15-year Supercomputing Conference tradition of highlighting the most innovative developments in high-performance computing and networking. Bringing together scientists, engineers, researchers, educators, programmers, system administrators and managers, SC2003 in Phoenix will demonstrate how these developments are sparking new ideas and new industries, as well as rekindling older ones. The conference features the latest scientific and technical innovations from around the world, while its SC Global events will showcase achievements in the arts and sciences among dozens of remote locations. SC2003 is sponsored by the Institute of Electrical and Electronics Engineers Computer Society and by the Association for Computing Machinery's Special Interest Group on Computer Architecture.
