ATLAS HPC Sites: Toward Common Solutions

Tuesday 19 Sept 2017, 14:00 → 16:00 Europe/Amsterdam

13/3-005 (CERN)

This meeting will focus on working out the details of how to continue pushing toward common solutions at large HPC facilities. This includes discussing Harvester(+Panda), Event Service, and Containers for Software Distribution.

14:00 → 14:40 Harvester Discussion

During this discussion we should talk about
- What features need to be added to or tested in Harvester before it should be passed on to OLCF, NERSC, and BNL?
- Are there pieces in Panda still missing that will help support HPC type queues?
- How do we handle planned outages without moving jobs around? We should support short outages (<= 1 day) where jobs should be diverted and long outages (> 1 day) where jobs can remain in place.

14:40 → 15:10 Data Motion

Discuss:
- Globus Online tools for Harvester and Rucio
- Dual End-points

15:10 → 16:00 Software Distribution

In this section we should discuss:
- How will the production of containers work?
- What releases will be included?
- How do we distribute them?
- How do we deal with the time lag between new releases appearing on CVMFS and having them on the site via container?
