A method of solving combinatorial problems, such as the N queens problem or graph coloring problems using independent parallel processes, is proposed. This method is stochastic (or randomized). Problems are decomposed for parallel processing implicitly and stochastically. This method is based on CCM, which is a computational model proposed by the author. A program consists of production rules a...

We Analyze data parallel programming of some general purpose methods in linear algebra. Specifically , the projection methods to solve very large linear system and/or eigenproblem. The expensive parts of these methods are their projection phases. This portion of these algorithms has generally, a very simple structure for such a programming model. It is composed essentially of matrix-vector mult...

This paper presents a novel parallel architecture for production systems. It relies on modern asso-ciative memory techniques to construct an environment in which productions can be red in parallel even before the actions of previously red productions are fully processed. This approach is made possible by the use of the serializabil-ity criterion for correctness. An approximate solution for the ...

CoQ10 and lycopene are isoprenoid compounds with nutraceutical and pharmaceutical benefits. In this study, the effect of concomitant lycopene biosynthesis on CoQ10 accumulation in transformed Escherichia coli DH5α was studied. A lycopene production pathway including geranylgeranyl diphosphate synthase (crtE), phytoene synthase (crtB), and phytoene desaturase (crtI) from Erwinia herbicola was co...

This paper describes the implementation of a parallel world model using Linux containers. A parallel world (or parallel universe) model allows a user to create multiple execution environments, called worlds, in a single operating system and to manipulate these worlds. This model enables a system administrator to create a new test world that looks like a production world. The system administrato...

in this research work, a novel parallel manipulator with high positioning and orienting rate is introduced. this mechanism has two rotational and one translational degree of freedom. kinematics and jacobian analysis are investigated. moreover, workspace analysis and optimization has been performed by using genetic algorithm toolbox in matlab software. because of decreasing moving elements, it i...

In the paper we discuss the influence of the route flexibility degree, the open rate of operations and the production type coefficient on makespan. The flexible job-open shop scheduling problem FJOSP (an extension of the classical job shop scheduling) is analyzed. For the analysis of the production process we used a hybrid heuristic of the GRASP (greedy randomized adaptive search procedure) wit...

Map/Reduce style data-parallel computation is characterized by the extensive use of user-defined functions for data processing and relies on data-shuffling stages to prepare data partitions for parallel computation. Instead of treating user-defined functions as “black boxes”, we propose to analyze those functions to turn them into “gray boxes” that expose opportunities to optimize data shufflin...

This contribution presents the ongoing development of a resource manager for use in early production grids. Even though our main focus is to develop a stable brokering facility for current production grids, we also address features needed in further improved resource managers for future enhanced grid infrastructures. The primary target environment is the NorduGrid platform, comprising around 20...

Concomitantly with recent advances in speech coding, recognition and production, parallel computer systems are now commonplace delivenng raw computing power measured in hundreds of MIPS and Megaflops. It seems inevitable that within the next decade or so, gigaflop parallel processors will be achievable at modest cost. Indeed, gigaflops per cubic foot is now becoming a standard of measure for pa...
