[Yahel Ben-David:] I’ll presume the hardware used is the easier case of MIPS. The x86 architecture complicates things as some instructions may silently fail if not run under a real “ring-0” privileges. Before delving into the flow of control for handling a system-call (syscall) on a virtualized system, let’s briefly discuss what happens in a traditional setting (without virtualization): When th...

Use of a logic state analyser as a hardware monitoring tool is described. The interrupt handling routines of the UNIX* operating system, running on a Perkin-Elmer 7/32, were measured before and after major code modification. CLock handLing is used as an example. Performance improvements included a reduction in the execution time of the common interrupt handler from 654 to 55 microseconds and a ...

Recent advances in I/O bus structures (e.g., PCI), highspeed networks, and fast, cheap disks have significantly expanded the I/O capacity of desktop-class systems. This paper describes a messaging system designed to deliver the potential of these advances for network storage systems including cluster file systems and network memory. We describe gms net, an RPClike kernel-kernel messaging system...

BACKGROUND In July 2005 an outbreak of acute gastroenteritis occurred on a residential summer camp in the province of Barcelona (northeast of Spain). Forty-four people were affected among residents and employees. All of them had in common a meal at lunch time on 13 July (paella, round of beef and fruit). The aim of this study was to investigate a foodborne norovirus outbreak that occurred in th...

Surface coatings that can help deter and solve gun crime are described. These nanoengineered coatings have been applied and evaluated on brass cartridge cases, where they increase associative forensic evidence through nanotag donation to the handler and the retention of handler's DNA. In future we expect this approach to be used for other surfaces and conditions.

JAVA is a general purpose concurrent class-based object-oriented programming language. This work presents an interactive program that interprets JAVA source programs directly. The cornerstone of its execution model is an execution graph, in which each node is constituted by three functions: a state transformer, a continuation and an exception handler.

Data on U.S. corn quality were summarized by geographic region and market location. There were significant variations in composition (protein, oil, starch) within and across regions. Intraregional composition differences are economically significant at the first handler level, but one uncontrolled commingling will eliminate any usable differences. Physical quality, as measured by U.S. grade fac...
