Abstract

The Worldwide LHC Computing Grid (WLCG) is today comprised of a range of different types of resources such as cloud centers, large and small HPC centers, volunteer computing as well as the traditional grid resources. The Nordic Tier 1 (NT1) is a WLCG computing infrastructure distributed over the Nordic countries. The NT1 deploys the Nordugrid ARC-CE, which is non-intrusive and lightweight, originally developed to cater for HPC centers where no middleware could be installed on the worker nodes. The NT1 runs ARC in the native Nordugrid mode which contrary to the Pilot mode leaves jobs data transfers up to ARC. ARCs data transfer capabilities together with the ARC Cache are the most important features of ARC. In this article we will describe the datastaging and cache functionality of the ARC-CE set up as an edge service to an HPC or cloud resource, and show the gain in efficiency this model provides compared to a traditional pilot model, especially for sites with remote storage.

Abstract

The first LHC application ever to be executed in a computational Grid environment is the so-called ATLAS Data-Challenge 1, more specifically, the part assigned to the Scandinavian members of the ATLAS Collaboration. Taking advantage of the NorduGrid testbed and tools, physicists from Denmark, Norway and Sweden were able to participate in the overall exercise starting in July 2002 and continuing through the rest of 2002 and the first part of 2003 using solely the NorduGrid environment. This allowed to distribute input data over a wide area, and rely on the NorduGrid resource discovery mechanism to find an optimal cluster for job submission. During the whole Data-Challenge 1, more than 2 TB of input data was processed and more than 2.5 TB of output data was produced by more than 4750 Grid jobs., Comment: Talk from the 2003 Computing in High Energy Physics and Nuclear Physics (CHEP03), La Jolla, Ca, USA, March 2003, 7 pages, 3 ps figures

Abstract

Information system is the backbone of any kind of a distributed Grid system. NorduGrid ARC was one of the first middlewares that came with a reliable and comprehensive information systemarchitecture. This solution, initially inspired by an LDAP-based approach of Globus, has beenused as a distributed dynamic database for Grid resource discovery and monitoring in researchinfrastructures for many years. This paper gives an overview of the system architecture, the un-derlying technology and features. Although the original ARC information system came with acustom information schema, the standard GLUE2 model is being broadly endorsed by middlewaredevelopers now. ARC contributed to the GLUE2 development, and is among the first to imple-ment it, as described in this paper. Ongoing new developments targeting further convergence andharmonization of otherwise different Grid information systems is also discussed., NorduGrid, European Middleware Initiative
