Аннотация:
Modern large-scale computing systems, such as data centers and high-performance
computing (HPC) clusters, are severely constrained by power and cooling costs
for solving extreme-scale (or exascale) problems. The relentless increase in power
consumption is of growing concern due to several reasons, e.g., cost, reliability,
scalability, and environmental impact. A report from the Environmental Protection
Agency (EPA) indicates that the nation’s servers and data centers alone use about
1.5% of the total national energy consumed per year, at a cost of approximately
$4.5 billion. The growing energy demands in data centers and HPC clusters are
of utmost concern and there is a need to build efficient and sustainable computing
environments that reduce the negative environmental impacts. Emerging technologies to support these computing systems are therefore of tremendous interest. Power
management in data centers and HPC platforms is getting significant attention both
from academia and industry. The power efficiency and sustainability aspects need to
be addressed from various angles that include system design, computer architecture,
programming language, compilers, networking, etc.
