MAY 24-28, 1999 • MINNEAPOLIS, MN
41st CUG Conference Final Program Welcome
Welcome to the 1999 CUG Conference! is a beautiful time of year here, and enthusiasm runs high as people begin to enjoy the outdoors after a long northern winter. From the bluffs of the mighty Mississippi River in We are excited to welcome everyone to Minneapolis for the the east, to the scenic shores of one of the largest fresh water 1999 CUG Conference. As the original home of Cray lakes in the world (Lake Superior), to the farms and prairies Research, it seems a fitting place to close out the millennium of the west, Minnesota provides a diverse offering for visi- and look ahead to the next. We are indeed at the end of an tors. Whether you like outdoor activities and sports, a quiet era, as the supercomputing paradigm has shifted from the respite in the northern woods, or just some time to see the "big iron" to an HPC world of high-performance commodity sights in the Twin Cities of Minneapolis and St. Paul, we processors. hope your stay will be memorable. The CUG Program Committee has planned an exciting week Minnesota is known for friendly but reserved people, who of technical sessions and discussions. Add to that good food, often are masters of understatement. To use the words of a grand night out in the elegant Minnesota History Center, Garrison Keillor, well-known Minnesota humorist and host an evening reception hosted by SGI, a special luncheon for of national public radio's "A Prairie Home Companion," we CUG newcomers, and a chance to meet with your colleagues think this conference will be "not too bad," which, translated in the comfortable setting of the downtown Minneapolis from understated Minnesota parlance, means it will be Marriott City Center Hotel. We think it will be a rewarding great! and important event for the the CUG community. The technical program promises to be excellent and we encourage you to peruse the program. In addition, we are excited to have as keynote speaker Dr. Cherri M. Pancake, John M. Sell Professor of Computer Science at Oregon State University. Network Computing Services, Inc. Minnesota is called the Land of 10,000 Lakes, and we hope you take some extra time to enjoy the environment. Spring Local Arrangements Chair Message from the CUG Program Committee

Call for Papers
You'll want to mark your calendars for the CUG "Event of the Millennium": our next CUG conference will be held from May 22 through 26, 2000, near Amsterdam in Nordwick, The Netherlands. Our hosts will be Technical University of Delft and Stichting Academisch Rekencentrum Amsterdam. You and your colleagues from other CUG sites are the key to the conference, so we wanted to give you time to start thinking about presenting a paper. The information and experience you share in your presentation will provide you with the opportunity to help your colleagues solve problems and develop solutions rel- evant to your work environment. Your paper will be organized under the following categories:
Group/Focus Area Communications and Data Management Mass Storage Networking Computer Services Operations User Services High Performance Solutions Applications Performance Visualization Operating Systems IRIX Security UNICOS Programming Environments Compilers and Libraries Software Tools Find a Group or Focus Chair during or after this conference (see the Contacts list on p. 29–33 of this Program) and discuss your ideas for your presentation. When you are ready to submit your abstract, use the on line form at the CUG home page, www.cug.org. It will be available by Sept. 15, 1999. Also check the CUG home page for guidelines for preparing and submitting your paper.
