“…File catalog services like LFC [7] represent with a logical name a set of physical file locations, in order to select the more convenient replica when needed. Many strategies are proposed [14,10,5] that aim to improve the use of the file catalog services by quantifying network costs.…”

The quality of the connectivity provided by the network infrastructure of a Grid is a crucial factor to guarantee the accessibility of Grid services, schedulate efficiently processing and data transfer activity on the Grid and meet QoS expectations. Yet most Grid application do not take into consideration the expected performance of the network resources they plan to use. In this paper we describe the effective use of a Grid Monitoring framework, whose measurements are used to introduce netwrok aware features in a legacy application. We use GlueDomains, a network monitoring framework oriented to Grid infrastructures that measures a small (although possibly extensible) set of network parameters. Such framework works off the shelf with minimal administrative effort, is reliable, and has a negligible impact on system operation. The deployment covers a Metropolitan Grid infrastructure, aimed at supporting a data intensive eScience application. We describe a real use case consisting of bulk data trasfers during the operation of the Grid for the Virgo experiment.

“…Hierarchical storage devices, in particular, exhibit huge differences in access latencies, ranging from seconds to several hours, depending whether the data is on disk or tape and whether the tape is already mounted or not. It is of paramount importance to any Data Grid architecture that these latency variations are appropriately taken into account [33]. Moreover, most hierarchical storage systems are already well established and used for daily production outside the Grid.…”

SUMMARYThe vision of Grid computing is to facilitate world-wide resource sharing among distributed collaborations. With the help of numerous national and international Grid projects this vision is becoming reality and Grid systems are attracting an ever increasing user base. However, Grids are still quite complex software systems whose efficient use is a difficult and error prone task.In this paper we present performance engineering techniques that aim to facilitate an efficient use of Grid systems, in particular systems that deal with the management of large scale data sets in the tera-and petabyte range (also referred to as Data Grids ). These techniques are applicable at different layers of a Grid architecture and we discuss the tools required at each of these layers to implement them. Having discussed important performance engineering techniques we investigate how major Grid projects deal with performance issues particularly related to Data Grids and how they implement the techniques presented.
