The lmbench suite of operating system microbenchmarks provides a set of portable programs for use in cross-platform comparisons. We have augmented the lmbench suite to increase its flexibility and precision, and to improve its methodological and statistical operation. This enables the detailed study of interactions between the operating system and the hardware architecture. We describe modifica...

Early type-safe operating systems were hampered by poor performance. Contrary to these experiences we show that an operating system that is founded on an object-oriented, type-safe intermediate code can compete with MMUbased microkernels concerning performance while widening the realm of possibilities. Moving from hardware-based protection to softwarebased protection offers new options for oper...

M have long been challenged by an abundance of internal and external demands and uncertainties in their operating environments. Anecdotal evidence and a growing number of research studies have advocated process flexibility and product innovation as organization-level operating capabilities critical for responding to such demands and uncertainties, and have highlighted the need for more efficien...

Traditionally, configuration of operating systems is done statically at compileor link-time, but recently dynamic runtime configuration has become possible. Embedded systems however have constraints, such as limited memory and real-time requirements, that prevent many dynamically configurable operating systems from being used in an embedded system. Dynamic configuration has associated limitatio...

Aura is a new sound synthesis system designed for portability and flexibility. Aura is designed to be used with W, a real-time object system. W provides asynchronous, priority-based scheduling, supporting a mix of control, signal, and user interface processing. Important features of Aura are its design for efficient synthesis, dynamic instantiation, and synthesis reconfiguration. operating syst...

Because of its power and flexibility, the UNIX operating system has become an almost standard tool for computer science. research. However, the UNIX user interface has been criticized as being cryptic, hard to leam, and hanl to use, particularly for novice users This paper presents a graphical shell interface for UNIX that preserves the power and flexibility of UNIX, while improving its ease of...

The new training literature suggests that in a monopsonistic market employers will not only pay for fi rm-specifi c training but also for general training if the risk of poaching is limited. This implies that training participation should decrease when competition for employees is higher among fi rms. Using worker level data for Germany we fi nd that the hypothesis is supported empirically. Spe...
