The Grid 2: Blueprint for a New Computing Infrastructure

A general interpolation method for constructing smooth molecular potential energy surfaces (PES’s) from ab initio data are proposed within the framework of the reproducing kernel Hilbert space and the inverse problem theory. The general expression for an a posteriori error bound of the constructed PES is derived. It is shown that the method yields globally smooth potential energy surfaces that are continuous and possess derivatives up to second order or higher. Moreover, the method is amenable to correct symmetry properties and asymptotic behavior of the molecular system. Finally, the method is generic and can be easily extended from low dimensional problems involving two and three atoms to high dimensional problems involving four or more atoms. Basic properties of the method are illustrated by the construction of a one‐dimensional potential energy curve of the He–He van der Waals dimer using the exact quantum Monte Carlo calculations of Anderson et al. [J. Chem. Phys. 99, 345 (1993)], a two‐dimensional potential energy surface of the HeCO van der Waals molecule using recent ab initio calculations by Tao et al. [J. Chem. Phys. 101, 8680 (1994)], and a three‐dimensional potential energy surface of the H+3 molecular ion using highly accurate ab initio calculations of Rohse et al. [J. Chem. Phys. 101, 2231 (1994)]. In the first two cases the constructed potentials clearly exhibit the correct asymptotic forms, while in the last case the constructed potential energy surface is in excellent agreement with that constructed by Rohse et al. using a low order polynomial fitting procedure.

A general method for constructing multidimensional molecular potential energy surfaces from ab initio calculations

The authors attempt to give a comprehensive discussion of observations of atomic negative-ion resonances throughout the periodic table. A review of experimental and theoretical approaches to the study of negative-ion resonances is given together with a consideration of the various schemes that are used for their classification. In addition to providing, where possible, tabulated data for the energies, widths, and symmetries of these states, the authors also attempt to highlight regularities in their behavior both within groups of the periodic table and along isoionic sequences.

Analysis of transient flow of MHD nanofluid past a non-linear stretching sheet considering Navier’s slip boundary condition

Grid computing is a form of distributed computing that involves coordinating and sharing computationa l power, data storage and network resources across dynamic and ge ographically dispersed organizations. Scheduling onto the Grid i s NP-complete, so there is no best scheduling algorithm for all gr id computing systems. An alternative is to select an appropriate scheduling algorithm to use in a given grid environment becaus e of the characteristics of the tasks, machines and network c nnectivity. Job and resource scheduling is one of the key research ea in grid computing. The goal of scheduling is to achieve hig hest possible system throughput and to match the application need with the available computing resources. Motivation of the su rvey is to encourage the amateur researcher in the field of gr id computing, so that they can understand easily the concept of sche duling and can contribute in developing more efficient scheduling al orithm. This will benefit interested researchers to carry out fu r her work in this thrust area of research. Keywords—Grid Computing, Job Scheduling, Resource Scheduling.

A Survey of Job Scheduling and Resource Management in Grid Computing

Purpose




The purpose of this paper is to assess steady, two-dimensional natural convection flow of a viscoelastic, incompressible, electrically conducting and optically thick heat-radiating nanofluid over a linearly stretching sheet in the presence of uniform transverse magnetic field taking Dufour and Soret effects into account.




Design/methodology/approach




The governing boundary layer equations are transformed into a set of highly non-linear ordinary differential equations using suitable similarity transforms. Finite element method is used to solve this boundary value problem. Effects of pertinent flow parameters on the velocity, temperature, solutal concentration and nanoparticle concentration are described graphically. Also, effects of pertinent flow parameters on the shear stress, rate of heat transfer, rate of solutal concentration and rate of nanoparticle concentration at the sheet are discussed with the help of numerical values presented in graphical form. All numerical results for mono-diffusive nanofluid are compared with those of double-diffusive nanofluid.




Findings




Numerical results obtained in this paper are compared with earlier published results and are found to be in excellent agreement. Viscoelasticity, magnetic field and nanoparticle buoyancy parameter tend to enhance the wall velocity gradient, whereas thermal buoyancy force has a reverse effect on it. Radiation, Brownian and thermophoretic diffusions tend to reduce wall temperature gradient, whereas viscoelasticity has a reverse effect on it. Nanofluid Lewis number tends to enhance wall nanoparticle concentration gradient.




Originality/value




Study of this problem may find applications in engineering and biomedical sciences,e.g. in cooling and process industries and in cancer therapy.
