Quine-McCluskey algorithm on GPGPU

April 26, 2013

This paper deals with parallelization of the Quine–McCluskey algorithm. This boolean function minimization algorithm has a limitation when dealing with more than four variables. The problem computed by this algorithm is NP-hard and runtime of the algorithm grows exponentially with the number of variables. The goal is to show that parallel implementation of the Quine–McCluskey...

Comparison of design and performance of snow cover computing on GPUs and multi-core processors

WSEAS Transactions on Information Science and Applications

Abstract: The aim of this work is the depth of the snow cover computing in the desired point
based on the geographical characteristics of a specific geographical point in a modeled
area. The measured data are known on few places. These places are coincident with
raingauge stations. These data have been collected by many continuous observations and
measurements at the specific...

Authorization through trust chains in ad hoc grids

Proceedings of the 2009 Euro American Conference on Telematics and Information Systems: New Opportunities to increase Digital Citizenship

Abstract Secure environment is a top-priority for all the forms of grid computing. To establish
trust, traditional grids use various methods, mostly centrally oriented ones, such as
certification authorities, VO management servers or credentials pools. Ad hoc grids are
characterized by the absence of a central trust authority; therefore collaborating entities must
establish and...

A neural tree model for classification of computing grid resources using PSO tasks scheduling

Neural Network World

Abstract: This paper proposes a model of neural tree architecture with probabilistic neurons.
These trees are used for classification of a large amount of computer grid resources to
classes. The first tree is used for classification of hardware part of dataset. The second tree
classifies patterns of software identifiers. Trees are implemented to successfully separate
inputs into...

Towards a VO Intersection Trust model for Ad hoc Grid environment: Design and simulation results

IAENG International Journal of Computer Science

Abstract—An ad hoc grid environment is a spontaneous organization of cooperating
heterogeneous nodes in a logical community without a fixed infrastructure and with only
minimal administrative requirements. Trust is an integral part of ad hoc grid computing
systems as well. It is not possible to utilize trust principles of traditional grid environment
uses various, mostly...

Evaluation of VO Intersection Trust model for Ad hoc Grids

Proceedings of the International MultiConference of Engineers and Computer Scientists

Abstract—Trust is an integral part of grid computing systems. Traditional grid environment
uses various, mostly centrally oriented methods for trust establishment, eg certification
authorities, VO management servers or credentials pools. On the other side, ad hoc grids
demand minimal administrative requirements; especially an absence of a central trust
authority, where...


A parallel processing of spatial data interpolation on computing cloud

Proceedings of the Fifth Balkan Conference in Informatics

Abstract In a short span of time, cloud computing has grown, particularly for commercial web
applications. But the cloud computing has the potential to become a greater instrument for
scientific computing as well. A pay-as-you-go model with minimal or no upfront costs creates
a flexible and cost-effective means to access compute resources. In this paper, we carry out
a study of...

GPGPU accelerated optimization method of Interconnection Network Topology

WSEAS Transactions on Information Science and Applications

Abstract: The optimization of the irregular connection network of the multiprocessor systems
with the distributed memory is the NP complete problem which is generally compute-
intensive process. Graphics processing units provide a large computational power at a very
low price allowing the fine-grained parallelism. This work investigates the use of the GPU in
the parallelisation of...
