Grid computing has enabled scientific communities to effectively share computing resources distributed over many independent sites. Several such communities, or Virtual Organizations (VO), in the Open Science Grid and the European Grid Infrastructure use the GlideinWMS system to run complex application work-flows. GlideinWMS is a pilot-based workload(More)
The SAM-Grid job management component does not currently regulate the flow of jobs to the execution sites. When multiple jobs are submitted to the same execution site, they all enter the gateway node more or less at the same time. Because job preparation at the gateway is a CPU intensive activity, we have observed high value of load (20) at the gateway(More)

The SciDAC Center for Enabling Distributed Petascale Science (CEDPS) seeks to accelerate DOE research by eliminating barriers to reliable and performant wide area data movement. A major focus of CEDPS R&D has been the development of Globus Online, a hosted data movement service to which users can hand off responsibility for a range of data movement tasks.(More)
The Open Science Grid (OSG) offers access to around hundred Compute elements (CE) and storage elements (SE) via standard Grid interfaces. The Resource Selection Service (ReSS) is a push-based workload management system that is integrated with the OSG information systems and resources. ReSS integrates standard Grid tools such as Condor, as a brokering(More)
