Abstract:
Large-scale scientific research often relies on the collaborative use of
Grid and e-Science infrastructures that other a wide variety of Grid
resources for scientists. While many production Grid projects and
e-Science infrastructures have begun to other services for the usage of
computational resources to end-users during the past several years, the
absence of a widely accepted standard for tracing resource usage of
Grid users has lead to different technologies among the infrastructures.
Recently, the Open Grid Forum developed a set of emerging standard
specifications, namely the Usage Record Format (URF) and the Resource
Usage Service (RUS) that aim to manage and expose user tracings.
In this paper, we present the integration of these standards into
the UNICORE Grid middleware that lays the foundation for valuable
tools in the area of accounting and monitoring. We present the development
of Grid extensions for the LLview application, which allows to
monitor the utilization (e.g. usage of cluster nodes per users) of Grid
resources controlled by Grid middleware systems such as UNICORE.
