Workshops - Wednesday, October 14
Building extreme-scale parallel systems and applications that can achieve high performance is a dauntingly difficult task. Today's systems have complex processors, deep memory hierarchies and plus complex I/O subsystems.
A particular focus this year will be on I/O and performance. I/O systems are becoming more complex with the addition of non-magnetic stable storage in the I/O hierarchy. In addition, the number of I/O nodes in leadership class machines now approaches the number of compute nodes in parallel machines only a few years ago.
Given this multi-disciplinary mix of performance and productivity, in this workshop we will concern their interplay across hardware, applications and system software design. The invited speakers will not only cover these areas, but will also address the state-of-the-art in methodologies for performance analysis and optimization including benchmarking, modeling, tools development, tuning and steering, as well as metrics for productivity.

Multimedia processors and FPGAs have become mainstream solutions in application domains requiring intensive computations over large data sets. What is beyond GPU, Cell, and FPGA? Is massive parallelism the magic bullet that could revolutionize performance in the face of slowing clock rates and bandwidth limits?
The Novel Computing Architectures workshop at the Los Alamos Computer Science Symposium (LACSS) seeks to explore future computing models and their realization in architectures capable of extreme performance (in non-cryogenic environments!). We will explore emerging research in non-traditional architectures and new approaches to old problems. Where will the industry be in 5-10 years? Will it be more of the same (but slower and more parallel) or are there revolutionary computing approaches/devices in our future?

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 the HPC Resiliency Summit is to bring together experts in the area of fault tolerance and resiliency for high-performance computing from national laboratories and universities to present their achievements and to discuss the challenges ahead. The secondary goal is to raise awareness in the HPC community about existing solutions, ongoing and planned work, and future research and development needs. The workshop program consists of a series of invited talks by experts and a round table discussion.
