Implementing Multithreaded Protocols for Release Consistency on Top of the Generic DSM-PM2 Platform

10.1007/3-540-47840-X_18DSM-PM2 is an implementation platform designed to facilitate the experimental studies with consistency protocoles for distributed shared memory. This platform provides basic building blocks, allowing for an easy design, implementation and evaluation of a large variety of multithreaded consistency protocols within a unified framework. DSM-PM2 is portable over a large variety of cluster architectures, using various communication interfaces (TCP, MPI, BIP, SCI, VIA, etc.). This paper presents the design of two multithreaded protocols implementing the release consistency model. We evaluate the impact of these consistency protocols on the overall performance of a typical distributed application, for two clusters with different interconnection networks and communication interfaces

TB database: an integrated platform for tuberculosis research

The effective control of tuberculosis (TB) has been thwarted by the need for prolonged, complex and potentially toxic drug regimens, by reliance on an inefficient vaccine and by the absence of biomarkers of clinical status. The promise of the genomics era for TB control is substantial, but has been hindered by the lack of a central repository that collects and integrates genomic and experimental data about this organism in a way that can be readily accessed and analyzed. The Tuberculosis Database (TBDB) is an integrated database providing access to TB genomic data and resources, relevant to the discovery and development of TB drugs, vaccines and biomarkers. The current release of TBDB houses genome sequence data and annotations for 28 different Mycobacterium tuberculosis strains and related bacteria. TBDB stores pre- and post-publication gene-expression data from M. tuberculosis and its close relatives. TBDB currently hosts data for nearly 1500 public tuberculosis microarrays and 260 arrays for Streptomyces. In addition, TBDB provides access to a suite of comparative genomics and microarray analysis software. By bringing together M. tuberculosis genome annotation and gene-expression data with a suite of analysis tools, TBDB (http://www.tbdb.org/) provides a unique discovery platform for TB research

On a coupled PDE model for image restoration

In this paper, we consider a new coupled PDE model for image restoration. Both the image and the edge variables are incorporated by coupling them into two different PDEs. It is shown that the initial-boundary value problem has global in time dissipative solutions (in a sense going back to P.-L. Lions), and several properties of these solutions are established. This is a rough draft, and the final version of the paper will contain a modelling part and numerical experiments

Information Warfare : A Philosophical Perspective

This paper focuses on Information Warfare – the warfare characterised by the use of information and communication technologies. This is a fast growing phenomenon, which poses a number of issues ranging from the military use of such technologies to its political and ethical implications. The paper presents a conceptual analysis of this phenomenon with the goal of investigating its nature. Such an analysis is deemed to be necessary in order to lay the groundwork for future investigations into this topic, addressing the ethical problems engendered by this kind of warfare. The conceptual analysis is developed in three parts. First, it delineates the relation between Informational Warfare and the Information revolution. It then focuses attention on the effects that the diffusion of this phenomenon has on the concepts of state and war. On the basis of this analysis, a definition of Information Warfare is provided as a phenomenon not necessarily sanguinary and violent, and rather transversal concerning the environment in which it is waged, the way it is waged and the ontological and social status of its agents. The paper concludes by taking into consideration Just War Theory and the problems arising from its application to the case of Informational Warfare.Peer reviewe
