Virtual machine placement (VMP) is an important issue in selecting the most suitable set of physical hosts for a set of virtual machines in cloud computing environment. VMP problem consists of two sub problems: incremental placement (VMiP) problem and consolidated placement (VMcP) problem. The challenge in VMcP problem is how to find optimal solution effectively and efficiently as well as it is...

Applications of Metric Embedding to Regular IC Optimization Ph. D. Dissertation Padmini Gopalakrishnan Department of Electrical and Computer Engineering Carnegie Mellon University Prof. Lawrence T. Pileggi, Chair In digital IC design methodologies, the design netlist is typically modeled as a graph or hypergraph, and information about its structure or topology is often used in optimization. Oft...

Retiming is a widely investigated technique for performance optimization. It performs powerful modifications on a circuit netlist. However, often it is not clear whether the predicted performance improvement is still valid after placement has been performed. This paper presents a new retiming algorithm using a highly accurate timing model. It takes into account the effect of retiming on capacit...

We apply our object-oriented design environment PAM-Blox to dynamic generation of circuits for recon gurable computing. Our approach combines the structural hardware design environment with commercial synthesis of nite state machines (FSMs). The PAM-Blox environment features a well de ned hardware object interface and the ability to control the placement of hand-optimized circuits. We integrate...

Optimal distribution substation placement is one of the major components of optimal distribution system planning projects. In this paper optimal substation placement problem is solved using Imperialist Competitive Algorithm (ICA) as a new developed heuristic optimization algorithm. This procedure gives the optimal size, site and installation time of medium voltage substation, using their relate...

The amount of hydrocarbon recovered can be considerably increased by finding optimal placement of non-conventional wells. For that purpose, the use of optimization algorithms, where the objective function is evaluated using a reservoir simulator, is needed. Furthermore, for complex reservoir geologies with high heterogeneities, the optimization problem requires algorithms able to cope with the ...
