Memory bandwidth is a highly performance-critical shared resource on modern computer
systems. To prevent the contention on memory bandwidth among the collocated workloads …

Workload consolidation is a commonly used approach for improving resource utilization of
commodity servers. However, colocated workloads often suffer from significant performance …

There is a consensus that exascale systems should operate within a power envelope of
20MW. Consequently, energy conservation is still considered as the most crucial constraint if …

In this article, we analyze performance and energy consumption of five OpenMP runtime
systems over a non-uniform memory access (NUMA) platform. We also selected three CPU …

Hyperspectral images have correlation at the level of pixels; moreover, images from
neighboring frequency bands are also closely correlated. In this paper, we propose to use …

Current Intel processors implement a variety of power saving features like frequency scaling
and idle states. These mechanisms limit the power draw and thereby decrease the thermal …

As the HPC community moves into the exascale computing era, application energy is
becoming as large of a concern as performance. Optimizing for energy will be essential in …

Cloud computing has become ubiquitous due to its resource flexibility and cost efficiency.
Resource flexibility allows Cloud users to elastically scale their Cloud resources, for …

A promising approach to improve the energy-efficiency of HPC applications is to apply
energy-saving techniques for different code regions according to their characteristics …

Abstract High Performance Computing (HPC) has become an indispensable tool for the
scientific community to perform simulations on models whose complexity would exceed the …
