Portable Parallel Irregular Applications

Software developers for distributed memory multiprocessors often complain about the lack of libraries and tools for developing and performance tuning their applications. While some tools exist for regular array-based computations , support for applications with pointer-based data structures, asyn-chronous communication patterns, or unpredictable computational costs is seriously lacking. In this...

A High Efficiency Low-Voltage Soft Switching DC–DC Converter for Portable Applications

This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute a major portion of the total power loss at light loads. To decrease the switching losses...

CORBA request portable interceptors: analysis and applications

Interceptors are a mean to add specific network-oriented capabilities (such as authentication, flow control, caching etc.) to a distributed application which runs over a middleware without changing either the application code or the middleware’s one. In this paper we present the results of an investigation on CORBA Portable Interceptors carried out on three JavaCORBA platforms. This study inclu...
