Energy-efficient resource allocation within computing systems is important because of the growing demand for, and cost of, energy. In this paper, we study the problem of energy-constrained static resource allocation of a collection of communicating tasks to a heterogeneous computing environment. Our goal is to maximize the probability (calculated via Monte Carlo method) that our collection of t...

Cloud computing is one of the rapidly improving technologies. It provides scalable resources needed for the applications hosted on it. As cloud-based services become more dynamic, resource provisioning becomes more challenging. The QoS constrained resource allocation problem is considered in this paper, in which customers are willing to host their applications on the provider’s cloud with a giv...

Background In order to meet the challenges presented by increasing demand and scarcity of resources, healthcare organizations are faced with difficult decisions related to resource allocation. Tools to facilitate evaluation and improvement of these processes could enable greater transparency and more optimal distribution of resources.   Methods The Resource Allocation Performance Assessment Too...

This paper presents a new cross-layer resource allocation model for multiuser packet-based Orthogonal Frequency Division Multiplexing (OFDM) systems, where the packet arrival process, delay QoS in the application layer and the subcarrier conditions for all users in the physical layer are considered in the MAC layer design. The objective of the proposed cross-layer resource allocation is formula...

In this paper, we propose a joint power-distortion optimization scheme for real-time H.264 video encoding under the power constraint. Firstly, the power constraint is translated to the complexity constraint based on DVS technology. Secondly, a computation allocation model (CAM) with virtual buffers is proposed to facilitate the optimal allocation of constrained computational resource for each f...

An operational economic model for radio resource allocation in the downlink of a multi-cell WCDMA1 system is developed in this paper, and a particle swarm optimization (PSO) based approach is proposed for its solution. Firstly, we develop an economic model for resource allocation that considers the utility of the provided service, the acceptance probability of the service by the users and the r...

The interaction between instruction scheduling and register allocation has signiicant impact on the quality of code generated, particularly in compilers targeting ne grain parallel architectures. The problem results from the fact that instruction scheduling and register allocation have connicting goals. Instruction scheduling tries to maximize parallelism by scheduling as many instructions as p...

This paper presents a scheduling approach, based on Ant Colony Optimization (ACO), developed to address the scheduling problem in manufacturing systems constrained by both machines and heterogeneous workers called as Dual Resource Constrained Job Shop Scheduling Problem with Heterogeneous Workers. This hybrid algorithm utilizes the combination of ACO and Simulated Annealing (SA) algorithm and p...
