چکیده

The introduction of multicore processors imply that algorithms which are parallelized at an outer, coarse grain level should possibly be revisited to examine if multithreading should also be used at an inner, fine grain level. In this paper we discuss parallel versions of the tightly coupled global optimization algorithm DIRECT. We examine how both coarse grained and fine grained parallelism can be exploited using a hybrid programming model. We show that excellent performance can be archived when using the hybrid algorithm on loosely-coupled systems like clusters and grids with multicore nodes.

Multi-objective and Scalable Heuristic Algorithm for Workflow Task Scheduling in Utility Grids

 To use services transparently in a distributed environment, the Utility Grids develop a cyber-infrastructure. The parameters of the Quality of Service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the Utility Grids. Optimization of both target parameters above is a challenge in a distributed environment and may conflict one an...

An Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...

Topic 1: Support Tools and Environments

The spread of systems that provide parallelism either "in-the-large" (grid infrastructures, clusters) or "in-the-small" (multi -core chips), creates new opportunities for exploiting parallelism in a wider spectrum of application domains. However, the increasing complexity of parallel and distributed platforms renders the programming, the use, and the management of these systems a costly endeavo...

Scaling relations in dynamical evolution of star clusters

We have carried out a series of small scale collisional N-body calculations of single-mass star clusters to investigate the dependence of the lifetime of star clusters on their initial parameters. Our models move through an external galaxy potential with a logarithmic density profile and they are limited by a cut-off radius. In order to find scaling relations between the lifetime of star cluste...

Model the allocation of productive financial resources from the perspective of livelihood poverty indicators using a combination of clustering methods and SAW technique

Poverty is a social, economic, cultural and political reality that has long been one of the greatest human problems. The diversity of problems, needs and problems of the deprived and low-income groups of the society and the multiplicity of poverty indicators on the one hand, and on the other hand the lack of financial resources and credits to solve the poverty indicators, organizations in charg...
