The CMS experiment expects to manage several Pbytes of data each year during the LHC programme, distributing them over many computing sites around the world and enabling data access at those centers for analysis. CMS has identified the distributed sites as the primary location for physics analysis to support a wide community with thousands potential users.(More)
In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC)[1] experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The(More)
The paper reports the development of a flexible and scalable testbed for the implementation and evaluation of signal processing algorithms for multiple antenna (MIMO) systems. At a maximum, four transmit and four receive antennas can be served. Two operational modes are targeted, non real-time block transmission and real-time operation.
The Large Hadron Collider (LHC) is preparing for data taking at the end of 2009. The Worldwide LHC Computing Grid (WLCG) provides data storage and computational resources for the high energy physics community. Operating the heterogeneous WLCG infrastructure, which integrates 140 computing centers in 33 countries all over the world, is a complicated task.(More)
Error handling is a crucial task in infrastructures as complex as grids. Today, there are several monitoring tools which can be used to report failing grid jobs including corresponding error codes. However, the error codes do not always indicate the actual fault which originally caused the job failure. Human time and expertise is required to manually trace(More)
