Energy minimization for nets with slack

Energy Minimization for Nets with Slack*

Slack allocation algorithm for energy minimization in cluster systems

Energy consumption has been a critical issue in high-performance computing systems, such as clusters and data centers. An existing technique to reduce energy consumption of applications is dynamic voltage/frequency scaling (DVFS). In this paper, we present a novel algorithm called EASLA for energy aware scheduling of precedence-constrained applications in the context of Service Level Agreement ...

Stresses in equilibrium configurations of inextensible nets with slack Miroslav

The paper deals with nets formed by two families of fibers (cords) which can grow shorter but not longer, in a deformation. The nets are treated as two dimensional continua in the three dimensional space. The inextensibility condition places unilateral constraint on the partial derivatives yÙ 1 and yÙ 2 of the deformation y Ú Ω r R 3 of the form |yÙ 1 x | 2 1Ù |yÙ 2 x | 2 1Ù x ̈ x1Ù x2 X Ω ⊂ R ...

Energy Minimization with Discontinuities

Many tasks in computer vision can be formulated as energy minimization problems. In this paper, we consider a natural class of energy functions that permits discontinuities. We show that minimizing these energy functions is NP-hard. However, the energy minimization problem can be solved by computing a minimum cost multiway cut on an associated graph. This allows the use of approximation algorit...

On Effective Slack Reclamation in Task Scheduling for Energy Reduction

Power consumed by modern computer systems, particularly servers in data centers has almost reached an unacceptable level. However, their energy consumption is often not justifiable when their utilization is considered; that is, they tend to consume more energy than needed for their computing related jobs. Task scheduling in distributed computing systems (DCSs) can play a crucial role in increas...
