Portlets for user centric job and task monitoring for open science grid virtual organizations

Abstract

Organizations in the Open Science Grid are motivated to provide services so that individual scientists can effectively execute data analysis jobs and take advantage of Grid resources. For success, these scientists will need to be able to monitor the execution status and application-level messages of their jobs that may run at any site within the Virtual Organization. In the Open Science Grid, the existing grid-wide tools provide abundant information about the whole system, but are geared towards Grid administrators, while information tailored towards individual users is not readily available except for the larger organizations that can afford to build their own tools. The User Centric Monitoring project addresses this gap by targeting a novel complete set of user-centric information including the status of a task of submitted jobs, queue positions, times of the start and finish, output and error messages, and reasons for failure. The toolkit is designed to provide flexible collection mechanisms and rich portlet-based presentation tool. This paper will describe the toolkit and portlet designs with a description of the most recent implementation progress.
