ARC v13.02 Release Announcement

February 28, 2013

The Advanced Resource Connector (ARC) middleware, introduced by NorduGrid (, is an open source software solution enabling production quality computational and data Grids since May 2002. The previous production ARC release, version 12.05u1, was released on November 8, 2012.

Upgrade and deployment notes

Upgrade is straightforward when standard Linux repositories are used. A-REX and GridFTPd will restart automatically, while infosystem services will need a manual start:

nordugrid-arc-slapd start
nordugrid-arc-bdii start
nordugrid-arc-inforeg start

In order to enable new features in the ARC Compute Element, changes in the arc.conf are needed, as described below.

For a first installation (from scratch), use of metapackages is recommended. Please consult ARC server and client deployment documentation.

Known issues (e.g., APEL accounting on Debian) are described below.
