Providing Multiple Service Classes for Bursty Data
{ This paper evaluates the use of packet scheduling to provide multiple service classes for bursty data traac. In particular, we study the performance of the weighted fair queueing algorithm by simulating various scenarios in a packet cellular wireless network similar to an EDGE system. The results show that, due to the burstiness of data traac, traditional work-conserving packet scheduling alg...
متن کاملHadronic Event-Shape Variables at CMS
In this note a study of hadronic event shapes in QCD events at the Large Hadron Collider (LHC) is presented. Calorimetric jet momenta, determined by various jet clustering algorithms, are used as input for calculating various event-shape variables which probe the structure of the hadronic final state. It is shown that the normalized event-shape distributions are robust under variations of the j...
متن کاملTowards a Metadata-driven Multi-Community Research Data Management Service
Nowadays, the daily work of many research communities is characterized by an increasing amount and complexity of data. This makes it increasingly difficult to manage, access and utilize to ultimately gain scientific insights based on it. At the same time, domain scientists want to focus on their science instead of IT. The solution is research data management in order to store data in a structur...
متن کاملTowards a Novel Metadata Information Service for Distributed Data Management
The trend in Grid computing towards more data intensive applications, accessing more and more relational databases and requiring advanced integration of secondhand and publicly available data sources, is still upstanding. Rich metadata information about these data sources plays a vital role for efficient distributed data management. There is a lack of service oriented monitoring tools providing...
متن کاملVirtual Data in CMS Production
Initial applications of the GriPhyN Chimera Virtual Data System have been performed within the context of CMS Production of Monte Carlo Simulated Data. The GriPhyN Chimera system consists of four primary components: 1) a Virtual Data Language, which is used to describe virtual data products, 2) a Virtual Data Catalog, which is used to store virtual data entries, 3) an Abstract Planner, which re...
