Registration Tech Program Accommodations Transportation Important Dates HPDC 2009

Recent trends in high-performance computing (HPC) systems have clearly indicated that future increases in performance, in excess of those resulting from improvements in single-processor performance, will be achieved through corresponding increases in system scale, i.e., using a significantly larger component count. As the raw computational performance of the world's fastest HPC systems increases from today's current tera-scale to next-generation peta-scale capability and beyond, their number of computational, networking, and storage components will grow from the ten-to-one-hundred thousand compute nodes of today's systems to several hundreds of thousands of compute nodes and more in the foreseeable future. This substantial growth in system scale, and the resulting component count, poses a challenge for HPC system and application software with respect to fault tolerance and resilience.

Furthermore, recent experiences on extreme-scale HPC systems with non-recoverable soft errors, i.e., bit flips in memory, cache, registers, and logic added another major source of concern. The probability of such errors not only grows with system size, but also with increasing architectural vulnerability caused by employing accelerators, such as FPGAs and GPUs, and by shrinking nanometer technology. Reactive fault tolerance technologies, such as checkpoint/restart, are unable to handle high failure rates due to associated overheads, while proactive resiliency technologies, such as preemptive migration, simply fail as random soft errors can't be predicted. Moreover, soft errors may even remain undetected resulting in silent data corruption.

The goal of this Workshop is to bring together experts in the area of fault tolerance and resiliency for HPC to present the latest achievements and to discuss the challenges ahead. Accepted papers will be included with the HPDC conference proceedings published by ACM. Resilience 2009 is the follow-on to the successful Resilience 2008 workshop held in conjunction with CCGrid in Lyon, France.
