We are happy to announce the release of ARC 6.13. You can read about the most important change related to the A-REX's Web Service interface in the release notes. In addition, as usual, this release comes with a few other improvements and bugfixes.
8 June
ARC 6.12 containing the important APEL changes is now available. This release addresses APEL migration from ActiveMQ messages brokers to AMS, which will take effect on July 1. If you publish accounting data to APEL, please be aware that you must update in good time before July 1st. Note that you also must change your arc.conf because old APEL servers will close. For more details, please consult the release notes.
23 April
We are happy to announce the release of ARC 6.11 This is a release mainly to push out a handful of smaller improvements and bug fixes. There is however one change: previosly, if a job description had no queue indicated (as in e.g. HTCondor clients), ARC-CE was forwarding the job as is to the batch system, which resulted in unexpected scheduling. Now ARC-CE will select a queue among those configured, depending on VO information. Read more configuration detail in the operations documentation.
15 February
ARC Release 6.10.1 is now available. It contains two important updates: to comply with GDPR, user DNs are not exposed, which breaks backwards compatibility with the older arcsync tool, and another fixes AREX crashed experienced by some sites. For more details, please consult the release notes.
2020
7 December
ARC Release 6.9.0 is out, featuring a technical preview of the REST interface. It is enabled on the CE by the [arex/ws/jobs] block in arc.conf. To use this interface with ARC clients, install the nordugrid-arc-plugins-rest package. We are keen for feedback to this interface, and expect a standard version to be ready in the new year.
Among other highlights is integration of the configuration validation tool arc-config-check into arcctl, a new movetool option for scratchdir, and improvements in the arcctl datastaging tool. For more details, please consult the release notes.
9 October
ARC 6.8.0 and an
express update 6.8.1 are now out,
the express release fixing the unintended behaviour during service restart after upgrade to 6.8.0.
The 6.8.x releases come with two important changes that
affect the update, namely changes in the accounting system, and a dependency on
xrootd5. Both will need manual steps when updating to ARC 6.8, the latter only if your CE has the
nordugrid-plugins-xrootd package installed.
For more details, please consult the release notes.

7 June
We are very happy to announce the first release of the ARC 6 series. ARC 6 comes with major re-engineering in the code base leading to improvements
in the deployment, configuration, maintenance and scalability of ARC CE.
It introduces many new features while some legacy interfaces, components and
features have been obsoleted and removed.
Despite all the new features and code changes the supported ARC 6 CE interfaces
are unchanged - the latest ARC 5 clients are compatible with an ARC 6 CE and vice versa.
With ARC 6 we hope to have greatly enhanced the ease of setting up, configuring
and managing an ARC production site, and to have improved the reliability and
scalability of the ARC CE by the internal restructuring ARC has undergone.
4 May

This year's Nobel Prize in Physics is the first to which ARC has proudly contributed. The theoretical work of Professors Englert and Higgs was supported by experimental data from ATLAS and CMS experiments at LHC, and ARC played a notable role in processing and analysing these data, as well as producing simulated data. Above 5% of all ATLAS and 9% of all CMS computing power has been provided via ARC, and these numbers are growing, as large HPC sites turn to ARC in order to provide computational support to LHC. Let's hope that this Nobel Prize is not the last that ARC will enable!

An immedate implication is that the standalone tarball will unpack by default into nordugrid-arc-standalone, thus the users that have the standalone setup done automatically via login scripts, should either change the directory name to nordugrid-standalone, or modify the login scripts, if they wish to use tags 0.5.38+.

Uppsala NorduGrid cluster up and running.
The Lund grid cluster has been upgraded to 6 Intel Pentium 1GHz processors.
Successfull test of Replica and Gsiftp in Uppsala.
The link between Uppsala and Copenhagen is established and tested in both directions.
From Uppsala to Copenhagen:
[ellert@ellert ~]$ globusrun -a -r lscf.nbi.dk GRAM Authentication test successful [ellert@ellert ~]$ globus-job-run lscf.nbi.dk/jobmanager /bin/echo "Hello World" Hello World
From Copenhagen to Uppsala:
[8]lscf:~> globusrun -a -r ellert.tsl.uu.se GRAM Authentication test successful [9]lscf:~> globus-job-run ellert.tsl.uu.se/jobmanager /bin/echo "Hello World" Hello World
The firewall only allows connections from lscf.nbi.dk
The software repository is set up (protected access).
NorduGrid mailing lists for general announcements and technical discussions are set up.
Resource specification form (Word Document) is available to be filled by the participants. List of contact persons and an updated list of DataGrid Testebed resources are available as well.
A Globus link was successfully established between Uppsala and Lund. The ellert.tsl.uu.se single machine was connected to the Lund Grid cluster through the grid.quark.lu.se master node.
Initially we experienced some problems setting up the connection due to the firewall of the Uppsala University. Although they were not very happy, the system administrators were convinced that for experimental purposes the firewall should be opened between the two sites. After this everything worked fine in both directions.
For the future it might be a good idea to configure the gatekeepers to use a restricted range of ports for their return connections by setting the GLOBUS_TCP_PORT_RANGE and GLOBUS_UDP_PART_RANGE environment variables. By doing this it will no longer be necessary to open the firewall for traffic on all ports, but only for a limited number of ports. This is probably safer, and could possibly be more acceptable to the security people.
The alpha release 4 of the Globus Datagrid software, obtained from the Globus CVS, was successfully installed on the Lund Grid Cluster. The fork and the PBS jobmanagers were both configured on the gatekeeper. The gatekeeper is called grid.quark.lu.se and the default ports were used for Globus services.
NorduGrid Certificate Authority has been set up.
The Lund cluster is up and ready for testing.
