Uniform Job Monitoring using the HPC-Europa Single Point of Access

Job monitoring in Grid systems presents an important challenge due to Grid environments are volatile, heterogeneous, not reliable and are managed by different middlewares and monitoring tools. We present the infrastructure that we have designed and implemented in the HPC-Europa European project that allows uniform access to job monitoring information from different virtual organizations. The presented system abstracts user to the complexities of the underlying systems of each middleware. The API that each center has to implement for providing access to its job monitoring information is explained. Finally, we show all the features that user can use in the portal to personalize his/her monitoring environment: how and which information has to be presented.
