Summary form only given. This paper considers fault-tolerance on the R-Mesh and LR-Mesh models. We propose a technique to identify a healthy submesh from a faulty model using the removal fault model. Then, we use scalable algorithms to simulate the faulty model on the resulting healthy submesh. We also extend this work to cover more restrictive variations(More)
A molecular dynamics (MD) system is defined by the position and momentum of particles and their interactions. Solving the dynamics numerically and evaluating the interaction is computationally expensive even for a small number of particles in the system. We are focusing on long-ranged interactions, since the calculation time is O(N<sup>2</sup>) for an N(More)
Recently, many parallel computing models using dynamically reconfigurable electrical buses have been proposed in the literature. The underlying characteristics are similar among these models, but they do have certain differences that can take form of restrictions on configurations allowed. This paper presents a constant time simulation of an R-mesh on an(More)
The reconngurable mesh R-Mesh has drawn much i n ter-est in recent years, due in part to its ability to admit extremely fast algorithms for a large number of problems. For these algorithms to be useful in practice, the R-Mesh must be scalable; that is, any algorithm designed for a large R-Mesh should be able to run on a smaller R-Mesh without signiicant(More)
The competencies (a set of specific knowledges, skills, attitudes and behaviors; <i>e.g.</i> stress handling, commitment, collaboration and identification of conflicts) of the employees of software organizations are a fundamental element for the success of a Software Process Improvement (SPI) initiative. We performed three case studies to identify the(More)
