thank you Paul Symposium on Multicore and New Processing Technologies A symposium exploring the capabilities and use of new high performance computing (HPC) technologies is taking place Aug. 13 – 14 on the campus of the University of Alaska Fairbanks in conference room 010 of the West Ridge Research Building. Space is limited for this free symposium and registration is required. The two-day symposium is hosted by the Arctic Region Supercomputing Center, a national leader in the ongoing evaluation of current and next-generation processing technologies to improve the speed, memory functions and efficiencies of supercomputers. ARSC is a charter member of the National Science Foundation’s Center for High Performance Reconfigurable Computing (CHPRC). According to ARSC Chief Scientist Greg Newby, the technology path of semiconductors coupled with user requirements has created a change in processing hardware. “Physical limitations and power challenges have led to the development of multicore processors,” he said. “At the same time, special-purpose processing units for non-HPC markets are able to provide substantial processing powers in some applications. These include field programmable gate arrays (FPGAs), graphical processing units (GPUs) and gaming processors such as the CELL BE processor, which can be used as a standalone processor or as an application acceleration co-processor.” Participants in the symposium will address the following questions: * How do applications scale with the multiplicity of cores, envisioning near-future petaFLOP systems with multiple cores in each CPU socket? * What hardware limitations and features, such as memory bandwidth and shared cache, impact scalability of applications? * How do graphical, gaming and reconfigurable processors compare in real-world applications? * Are existing operating systems adequate to deal with those technologies? If not, what is missing and how can shortcomings be addressed? * What programming tools are currently available for those technologies, and what new tools are needed? “In order to address these and other questions of relevance to the high performance computing community, ARSC is taking the lead once again in this area by holding this summer symposium on multicore and new processing technologies,” Newby said. Invited speakers and discussion panels will include a number of experts to pose and address these and other issues in greater details.
