June 27, 2019

We are happy to announce the ARC 6.1.0 release, the first update of the ARC 6 series.

ARC 6.1.0 contains several bug fixes and the release also includes enhancements and new features as can be seen from the merge requests listed below.

Known issue

Sites using SLURM and the system-installed ENV/PROXY must add a slurm_requirements field in arc.conf in ARC 6.1.0. This is to mitigate a discovered bug that prevents the ENV/PROXY RTE updated in ARC 6.1.0 from working correctly.
Under the [lrms] block, please add the line:

slurm_requirements = --export=NONE
Note also that if you are using a patched submit-SLURM-job script, please make sure to update the base script using the one issued with ARC 6.1.0.

Now that ARC 6.1.0 is released, we will only provide security updates of ARC 5.

In particular:

  1. No new feature development is planned or going on for ARC5 and no bug-fixing development will happen on ARC5 code base in the future except for security issues.
  2. Security fixes for ARC5 will be provided till end of June 2020.
  3. Production Sites already running ARC 5 will be able to get deployment and configuration troubleshooting help via GGUS till end June 2021. This we call "operational site support".
