Stephen ScottOak Ridge National Laboratory"High-Availability in High-Performance Computing"
Date: Thursday, October 21, 2004
Abstract:Many organizations require tremendous computing power to solve their important problems such as Energy, Climate, Fusion, Biology, and Nanotechnology. These non-trivial problems are usually characterized by massive and long running applications. Therefore, Reliability, Availability and Serviceability (RAS), with respect to the computing hosts, have become very important. RAS management goals are to maximize uptime and therefore undoubtedly complements High End Computing (HEC) objectives by preventing performance degradation/spectrum availability. High Availability (HA) Computing has long played a critical role in commercial mission critical applications. Likewise, High Performance Computing (HPC) has equally been a significant enabler of the R&D community for their scientific discoveries. Serviceability aims toward effective means by which corrective and preventive maintenance can be performed on a system. Higher serviceability improves availability and helps sustaining quality, performance and continuity of services at expected levels. Together, the combination of HA, Serviceability, and HPC will clearly lead to even more benefits to critical shared major HEC resource environments. This talk will discuss some of the problems and issues surrounding high-availability in high end computing. It will also cover some current solutions as well as a discussion of our future directions in solving this problem.
