Release Notes for NorduGrid ARC 6.11

April 22, 2021

We are happy to announce the release of ARC 6.11.0

Highlights in this release

This is a release mainly to push out a handful of smaller improvements and bug fixes.

There is however one longstanding "feature" which has been improved in this release. Namely, the queue selection when there is no queue infomation from the client side.

From now on, if no queue is requested/selected from the client side, only queues configured in arc.conf will be among the possible queues to use.

This will avoid the surprising feature that the queue selection in this case is up to the batch system, and not ARC for such clients. This is not an issue when the ARC client is used.

Note that this means that from now you must ensure that the authgroups you wish to allow submission from, are authorized in the queue you intend the authgroup to submit to. Otherwise the submission will be rejected.

For details, please see the documentation on the subject.

The following Bugzilla tickets have been adressed or solved

Installing ARC 6

We recommend to install ARC release using the Nordugrid repository.

Note that if you instead install from EPEL for RHEL7 compatible systems, the ARC 6 packages can be found as nordugrid-arc6-* and not nordugrid-arc-*. This was needed in order to supply both ARC 5 already available for RHEL7 and the new ARC 6.

We provide binary builds for all supported versions of:

In addition we build nightly packages for older platforms.

Future Support of ARC 5-series

As of June 2020 no more security updates are provided to ARC 5. Also since the release of ARC 6 in June 2019, no more development on the ARC 5 code base has been provided.

Production Sites already running ARC 5 will still get operational site support in form of deployment and configuration troubleshooting help via GGUS until end June 2021. However, we may recommend upgrading to ARC 6 depending on the issues the site is facing.

ARC5 is available in EPEL7 and will stay there. EPEL8 will only contain ARC 6. To install ARC 6 from EPEL7 the package-names are of type: nordugrid-arc6-*
