Speakers will be chosen based on 1-page abstracts submitted to the ScicomP12 website () by 28 April. ABOUT SCICOMP: ScicomP meetings target computational scientists and engineers interested in achieving maximum performance and scalability on all of IBM's HPC platforms. This meeting will span the new and exciting range of IBM technologies including POWER architecture, Federation switch, BlueGene/L, and beyond. Presentations will be a balance of HPC users and the IBM R&D staff that produce and maintain them. User presentations focus on real world experiences in porting, maintaining, and running codes on large scale IBM systems. Issues may include (but are not limited to) code migration, scalable algorithms, hybrid programming models, exploiting system architectures, and scheduling and execution frameworks. IBM staff presentations include hardware and software roadmaps for large systems; application development support software tools; performance programming, measurement, analysis, and tuning techniques. ABOUT SP-XXL: NCAR will also host the SP-XXL () as a co-located meeting. The SP-XXL is a membership-based organization with systems-oriented interests in large-scale scientific technical computing on IBM hardware. ABOUT NCAR and BOULDER: NCAR is a federally funded research and development center in Boulder, Colorado, that was established in 1960. Together with our partners at universities and research centers, we are dedicated to exploring and understanding the Earth's atmosphere and its interactions with the Sun, the oceans, the biosphere, and human society. Boulder is proud to be one of Colorado's foremost havens of commerce, education, research and recreation. Cresting over the hill on highway 36 into Boulder, it's easy to see why this intriguing town has been dubbed "the city nestled between the mountains and reality." At 5,430 feet above sea level, acres of vast open space roll into Boulder's quaint cityscape tucked into the foothills of the Rocky Mountains. Located 35 miles northwest of downtown Denver, Boulder is a captivating mountain community enriched with natural beauty, hip urban culture and a vibrant love of the outdoors.
