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...

(Benzoyl­acetonato-κ2 O,O′)dicarbonyl­rhodium(I)

In the title compound, [Rh(C10H9O2)(CO)2], a distorted square-planar coordination geometry is observed around the Rh(I) atom, formed by the O atoms of the bidentate ligand and two C atoms from the carbonyl ligands. The Rh(I) atom is displaced from the plane through the surrounding atoms by 0.017 Å. In the crystal, C-H⋯O inter-action is observed between a methyl group of the bidentate ligand and...

Understanding I/O Performance Using I/O Skeletal Applications

We address the difficulty involved in obtaining meaningful measurements of I/O performance in HPC applications, as well as the further challenge of understanding the causes of I/O bottlenecks in these applications. The need for I/O optimization is critical given the difficulty in scaling I/O to ever increasing numbers of processing cores. To address this need, we have pioneered a new approach t...
