Installing ARC 6

We recommend to install ARC release using the Nordugrid repository.

• Start with the basics
• Get production ready

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:

• Debian (i386 and amd64)
• Fedora (x86_64)
• CentOS/RHEL (x86_64)
• Ubuntu (i386 and amd64, both LTS and interim releases) - from Ubuntu 20.04 no i386 support

In addition we build nightly packages for some older platforms.

Contributing

You can submit pull requests to our public repo which mirrors our GitLab repo.

The pull requests will be automatically copied over to our Gitlab repo where they will be merged into the source-code if accepted.

Known issues

• Related to the new accounting system introduced in release 6.4.0:
  Accounting records created by ARC 6.4.0 are affected by a bug causing missing benchmark values: see bug #3921. Recommendations are to update to a newer version of ARC. The bugreport gives instructions on how to manually fix the wrong benchmark values.
