Application software development for High-Performance Parallel Computing (HPC) is a non-trivial process; its complexity can be primarily attributed to the increased degrees of freedom that have to be resolved and tuned in such an environment. Performance prediction tools enable a developer to evaluate available design alternatives and can assist in HPC application software development. In this ...

Software development for High Performance (paral-lel/distributed) Computing (HPC) is a non-trivial process ; its complexity can be primarily attributed to the increased degrees of freedom that have to be resolved and tuned in such an environment. Performance prediction tools enable a developer to evaluate various available design alternatives and can assist in HPC application software developme...

1. INTRODUCTION Interpretive code simulations play an essential role in divertor/edge physics, firstly, because the edge is intrinsically complicated: at least 3 states of matter are involved; the shape of the region is problematical: long, narrow, twisted, inaccessible; edge modeling must be at least 2D; etc. Meaningful interpretive exercises therefore require that a data set of edge measureme...

adopting a humanistic, communicative-based approach to semiotics, this paper aims at investigating the status of linguistic signs and their interaction with other communicative signs. the status of linguistic sign is first studied in semiotic theories spanning ancient, middle ages and modern era. based on the commonalities envisaged in four contemporary semiotic theories done in the spirit of t...

This paper aims at examining how the adoption of a new Enterprise Resource Planning (ERP) system challenges the definition of the expertise and roles of accountants within organisations. By drawing on structuration theory, as we rely on the notion of duality of structure for insights into the processes by which new accountants’ practices and positions emerge, we indicate that the three levels (...

The paleoclassical model for radial electron heat transport in tokamak plasmas has been developed in a number of papers over the past few years. In order to facilitate numerical evaluation of it in plasma transport codes, this report summarizes its parameters, formulas and limits in particular regimes. A hierarchy of levels of the paleoclassical model are specified for interpretive (1) and pred...

In this paper we present a novel interpretive approach for accurate and cost-eeective performance prediction in a high performance computing environment , and describe the design of a source-driven HPF/Fortran 90D performance prediction framework based on this approach. The performance prediction framework has been implemented as part of a HPF/Fortran 90D application development environment. A ...

in this paper, we consider a class of column-weight two quasi-cyclic low-density paritycheck codes in which the girth can be large enough, as an arbitrary multiple of 8. then we devote a convolutional form to these codes, such that their generator matrix can be obtained by elementary row and column operations on the parity-check matrix. finally, we show that the free distance of the convolution...
