The development of a recent technological product, referred to as Array of Conngurable Logic Cells, promotes many opportunities for research and implementationof digital circuits. These arrays include logic cells whose functions can be dynamically speciied by the user. The paper describes the main characteristics of conngurable cells, and indicates the potential use of these arrays for research...

The relevance of security as one of the major contributors to an effective operational infrastructure has been growing in importance over the past 3-5 years, and today it resides as one of the two top investment priorities for senior management (the other one being critical server virtualization). Effective management by organizations when dealing with targeted and multiple parallel attacks com...

Light-Weight Parallel I/O Analysis at Scale

Input/output (I/O) operations can represent a significant proportion of the run-time when large scientific applications are run in parallel. Although there have been advances in the form of file-format libraries, file system design and I/O hardware, a growing divergence exists between the performance of parallel file systems and compute processing rates. In this paper we utilise RIOT, an input/...

Clotho: Transparent Data Versioning at the Block I/O Level

Recently storage management has emerged as one of the main problems in building cost effective storage infrastructures. One of the issues that contribute to management complexity of storage systems is maintaining previous versions of data. Up till now such functionality has been implemented by high-level applications or at the filesystem level. However, many modern systems aim at higher scalabi...
