The emergence of multi-core computers has led to explosive development of parallel applications and hence the need of efficient schedulers for parallel jobs. Adaptive online schedulers have recently been proposed to exploit the multiple processor resource and shown good promise in theory. To verify the effectiveness of these parallel schedulers, it will be reassuring to test them extensively with...
A self adaptive communication protocol is proposed for peer to peer distributed computing. This protocol can configure itself automatically in function of application requirements and topology changes by choosing the most appropriate communication mode between peers. The protocol was designed in order to be used in conjunction with a decentralized environment for high performance distributed computing...
Intrusion Detection Systems (IDS) deploy various sensors that collect data, process this data and report events. The process of combining these events or superordinate incidences is known as event correlation. The key issues of this process are (1) to find a way how to combine events based on different data types (e. g. log entries, connection statistics or protocol identifiers), (2) to build a model...
Many parallel applications in MPSoCs take advantage of multicast communication. Several multicast schemes such as path-based, tree-based, and unicast-based have been proposed in interconnection networks. Path-based multicast scheme has been proven to be more efficient than the other schemes in on-chip interconnection network. A new adaptive routing model based on Hamiltonian path for both the multicast...
Pervasive Grid Computing Platforms include centralized computing nodes (e. g. parallel servers) as well as decentralized and mobile devices. Pervasive Grid applications include data- and computing-intensive components which can be mapped also onto decentralized and mobile nodes. The effective and practical success of this mapping resides also in deriving proper configurations of applications which...
Defining performance models associated with the application structure has been proven a useful strategy for implementing dynamic tuning tools. However, for extending this strategy to more complex applications (those composed by different structures) it must integrate a policy for the distribution of the resources among the different application components. Consequently, we propose to take advantage...
FAFNER is code developed by Lister which simulates by Monte Carlo methods the Neutral Beam Injection (NBI) technology, one of the most extended heating methods for fusion devices. To the date, FAFNER has been usually run at CIEMAT adapted to the TJ-II helical axis stellarator on shared memory Cray architecture machines. From this version, FAFNER has been ported to the Grid in the framework of the...
