摘要：The NorduGrid collaboration and its middleware product, ARC (the Advanced Resource Connector),
span institutions in Scandinavia and several other countries in Europe and the rest of the
world. The innovative nature of the ARC design and flexible, lightweight distribution make it an
ideal choice to connect heterogeneous distributed resources for use by HEP and non-HEP applications
alike. ARC has been used by scientific projects for many years and through experience it
has been hardened and refined to a reliable, efficient software product. In this paper we present the
architecture and design of ARC and show how ARC’s simplicity eases application integration and
facilitates taking advantage of distributed resources. Example applications are shown along with
some results from one particular application, simulation production and analysis for the ATLAS
experiment, as an illustration of ARC’s common usage today. These results demonstrate ARC’s
ability to handle significant fractions of the computing needs of the LHC experiments today and
well into the future.
