Grid computing has become very popular in big and widespread scientific communities with high computing demands, like high energy physics. Computing resources are being distributed over many independent sites with only a thin layer of Grid middleware shared between them. This deployment model has proven to be very convenient for computing resource(More)
The Open Science Grid offers access to hundreds of computing and storage resources via standard Grid interfaces. Before the deployment of an automated resource selection system, users had to submit jobs directly to these resources. They would manually select a resource and specify all relevant attributes in the job description prior to submitting the job.(More)
The Advanced Networking Initiative (ANI) project from the Energy Services Network provides a 100 Gbps test bed, which offers the opportunity for evaluating applications and middleware used by scientific experiments. This test bed is a prototype of a 100 Gbps wide-area network backbone, which links several Department of Energy (DOE) national laboratories,(More)
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 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)
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)
Goal of the SAM-Grid / LCG interoperability project is making available to DZero the resources provided by the LHC Computing Grid (LCG) through the SAM-Grid system. In the months between March and June, the collaboration has put in place a “proof-of-principle” test bed, which demonstrated the feasibility of the integration project. The trip to Lyon was an(More)
Exascale science translates to big data. In the case of the Large Hadron Collider (LHC), the data is not only immense, it is also globally distributed. Fermilab is host to the LHC Compact Muon Solenoid (CMS) experiment's US Tier-1 Center, the largest of the LHC Tier-1s. The Laboratory must deal with both scaling and wide-area distribution challenges in(More)
