41St CUG Conference Final Program Welcome 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.

Computational manipulation of such large graphs is common, but previous tools for graph visualization have been limited to datasets of a few thousand nodes.

  • Accelerated Medical Image Registration Using the Graphics Processing Unit
    UNIVERSITY OF CALGARY Accelerated Medical Image Registration using the Graphics Processing Unit by Daniel Henrik Adler A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF ELECTRICAL AND COMPUTER ENGINEERING CALGARY, ALBERTA JANUARY, 2011 © Daniel Henrik Adler 2011 Abstract Registration of three-dimensional images is an important task in biomedical sci- ence. However, computational costs of 3D registration algorithms have hindered their widespread use in many clinical and research workflows. We describe an automated medical image registration framework, including a novel implementation of the mu- tual information similarity metric, that executes entirely on the commodity graphics processing unit (GPU). Our methods take advantage of the graphics hardware’s high computational parallelism and memory bandwidth to perform affine, intensity-based registration of multi-modal 3D medical images at near interactive rates. We also ac- celerate the Demons algorithm for deformable registration on the GPU. Registration results generated using our GPU-based methods are equivalent to those generated by conventional software-based methods, but with an order of magnitude reduction in computation time. ii Acknowledgements Ithankmylabmates,supervisor,andclosefriendsandfamilyfortheirsupport throughout my graduate studies.
