Remote storage management in science gateways via data bridging

摘要

State-of-the-art science gateways can be connected to several distributed computing infrastructures (DCIs)rnand are able to run jobs and workflows simultaneously in all those DCIs. Flexibility of accessing diverserndata storages from these workflows and assisting end users to manage these storages are however thernmissing features in current gateway implementations, in which these problems often prove to be a barrierrnof exploiting the power of distributed computing by user communities having no or little IT competence.rnThis paper addresses these issues by integrating a data bridging service called Data Avenue intornWS-PGRADE/gUSE portal framework. Data Avenue offers tools for the end users to easily manage theirrndata residing on various storage resources, and also, jobs become capable of accessing different storagesrnregardless of the particular distributed computing infrastructure where the job is currently being run.
