Release Announcement for NorduGrid ARC 13.11

November 27, 2013

The Advanced Resource Connector (ARC) middleware is an Open Source software solution to enable distributed computing infrastructures with the emphasis on processing large volumes of data. ARC provides an abstraction layer over computational resources, complete with input and output data movement functionalities. The security model of ARC is identical to that of Grid solutions, relying on delegation of user credentials and the concept of Virtual Organisations. ARC also provides client tools, as well as API in C++, Python and Java.

ARC development is coordinated by the NorduGrid Collaboration. The previous production ARC release, version 13.02u3, was out on July 19, 2013.
