HPCC has moved into the mainstream of computing and become a key technology in determining future research and development activities in many academic and industrial branches, especially when the solution of large and complex problems must cope with very tight timing schedules.\u003C\/p\u003E\n\u003Cp\u003EIn his keynote, Bader discusses several graph theoretic kernels for connectivity and centrality and how the features of petascale architectures will affect algorithm development, ease of programming, performance, and scalability. Graph theoretic problems are representative of fundamental kernels in traditional and emerging computational sciences such as chemistry, biology, and medicine, as well as applications in national security. However, they pose serious challenges for parallel machines due to non-contiguous, concurrent accesses to global data structures with low degrees of locality. Few parallel graph algorithms outperform their best sequential implementation due to long memory latencies and high synchronization costs.\u003C\/p\u003E\n\u003Cp\u003EThe HPCC conference series provides a forum for engineers and scientists in academia, industry, and government to address all resulting profound challenges, and to present and discuss their new ideas, research results, applications, and experience on all aspects of high performance computing and communication.\u003C\/p\u003E\n\u003Cp\u003EIn addition to three keynotes, the HPCC \u002706 conference held on September 13-15, included 95 peer-reviewed papers from 328 submissions, including papers from Europe, Asia and the Pacific, as well as North and South America.\u00a0 HPCC is emerging as the premier academic high-performance computing conference based in Europe.
