High performance computing systems will need to operate with certain power budgets while maximizing performance in the exascale era. Such systems are built with power aware components, whose collective peak power may exceed the specified power budget. Cluster level power bounded computing addresses this power challenge by coordinating power among components within compute nodes and further adjusting...
Power is a critical factor that limits the performance and scalability of modern high performance computer systems. Considering power as a first-order constraint and a scarce system resource, power-bounded computing represents a new perspective to address the power challenge in HPC.In this work we present an application-aware, multi-dimensional power allocation framework to support power-bounded parallel...
Many high performance large-scale storage systems will experience significant workload increases as their user base and content availability grow over time. The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) center hosts one such system that has recently undergone a period of rapid growth as its user population grew nearly 400% in just about three years. When administrators...
Data-intensive workloads demand a large portion of data center resources and consume massive amounts of energy. Energy conservation for data-intensive computing requires enabling technology to provide detailed and systemic energy information and to identify the energy inefficiencies in the underlying system hardware and software. In this work, we address this need and present eTune, a fine-grained,...
