“…For example, on Extreme Science and Engineering Discovery Environment (XSEDE), we may monitor jobs using both pull approaches (‘qstat’ or similar Grid mechanisms) or through push messaging. We implement the latter with the Messaging component described earlier and can also consume messages provided by the resources . If the job completes successfully, the gateway user can download outputs from the remote resource via Airavata. GFAC is responsible for staging files off the machine and back to the gateway.…”

Abstract-This paper provides an overview of the Apache Airavata software system for science gateways. Gateways use Airavata to manage application and workflow executions on a range of backend resources (grids, computing clouds, and local clusters). Airavata's design goal is to provide component abstractions for major tasks required to provide gateway application management. Components are not directly accessed but are instead exposed through a client Application Programming Interface. This design allows gateway developers to take full advantage of Airavata's capabilities, and Airavata developers (including those interested in middleware research) to modify Airavata's implementations and behavior. This is particularly important as Airavata evolves to become a scalable, elastic "platform as a service" for science gateways. We illustrate the capabilities of Airavata through the discussion of usage vignettes. As an Apache Software Foundation project, Airavata's open community governance model is as important as its software base. We discuss how this works within Airavata and how it may be applicable to other distributed computing infrastructure and cyberinfrastructure efforts.

“…The Information Publishing Framework (IPF) [7], [8] is software developed as part of XSEDE [9] to gather and publish information about clusters. It provides static and dynamic information about a cluster including descriptions of the compute nodes, batch scheduling queues, and jobs being managed by the batch scheduler or IaaS cloud software.…”

This paper describes an information system designed to support the large volume of monitoring information generated by a distributed testbed. This monitoring information is produced by several subsystems and consists of status and performance data that needs to be federated, distributed, and stored in a timely and easy to use manner. Our approach differs from existing approaches because it federates and distributes information at a low architectural level via messaging; a natural match to many of the producers and consumers of information. In addition, a database is easily layered atop the messaging layer for consumers that want to query and search the information. Finally, a common language to represent information in all layers of the information system makes it significantly easier for users to consume information. Performance data shows that this approach meets the significant needs of FutureGrid and would meet the needs of an experimental infrastructure twice the size of FutureGrid. In addition, this design also meets the needs of existing distributed scientific infrastructures.
