This paper shows an effective methodology to parallelize DNSSEC using an algorithmic skeleton library: Skandium. DNSSEC is the Domain Name System (DNS) Security Extensions. DNSSEC provides a set of backward compatible extensions to the DNS that secure the domain name resolution process. The application of these extensions to a domain zone introduces new CPU intensive tasks, where parallelism can be...
A file data model for algorithmic skeletons is proposed, focusing on transparency and efficiency. Algorithmic skeletons correspond to a high-level programming model that takes advantage of nestable programming patterns to hide the complexity of parallel/distributed applications. Transparency is achieved using a workspace factory abstraction and the proxy pattern to intercept calls on File type objects...
This paper addresses the issue of type safe algorithmic skeletons. From a theoretical perspective we contribute by: formally specifying a type system for algorithmic skeletons, and proving that the type system guarantees type safety. From an implementation point of view, we show how it is possible to enforce the type system on an Java based algorithmic skeleton library. The enforcement takes place...
The innermost part of the ATLAS (A Toroidal LHC Apparatus ) experiment at the LHC (Large Hadron Collider), CERN (Conseil Eurpeenne pour la Recherche Nucleaire), is a pixel detector. To operate the readout electronics and other detector components, a complex power supply and control system is necessary. The paper describes one of the components of which the power supply system is made of: the remotely...
