NICOS2@ESS - technical aspects

12:00 Meet & greet

Meet & greet for those who have not met before, combined with some lunch

1 Deployment & dependencies

Discussion topics: - How does FRMII handle deployment of NICOS to the instruments? - Dependency handling: split debian "meta-packages" (for GUI, daemon, etc) exist, should be similar for Centos? - PyPI/Custom FRMII package index - how to handle those dependencies automatically? - Good way to handle "special dependencies", e.g. on instrument level?

2 Detectors and data streaming

Discussion topics: - Short overview of ESS streaming architecture - If possible, short overview of how various parts of Detector and the different "sinks" work together in NICOS - What are good integration points between NICOS and bits of the streaming architecture (aggregator, file writer)? - If possible, Mark Könnecke could elaborate on "Data Interface" concept - Kafka integration in two directions (e.g. Kafka-based detector channels) - Pushing non-EPICS devices/parameters from NICOS into Kafka - implement as cache client?

15:15 Coffee

3 NICOS & Mantid

Discussion Topics: - Integration between NICOS and Mantid - what are the options (GUI, ...) - Prototype work by Michael Hart for integration of InstrumentView

4 Logging

Discussion topics: - Short overview of DMSC graylog infrastructure - Necessary modifications of/additions to NICOS logging backend

5 EPICS

Discussion topics: - Improvement of current EPICS implementation - Support for PV Access in addition to Channel Access - ways to avoid duplicate inheritance trees? - Discussion of functionality overlap (EPICS Archiver, Alarm Server) - Any special FRMII requirements that need to be considered?

17:30 Dinner & transfer to Malmö

7 Organisation of collaboration

Discussion topics: - Accounts & access: How to handle new developers at ESS, "get started" document with information for new developers - ESS specific developments: Where should they live in the source code and how are decisions made regarding dependencies - Handling of source - maintain fork for "experiments" or even perpetually? - Policies: Who decides what goes into the core of NICOS and how may ESS be a part of decisions that affect them (changing protocols, update paths for dependencies, etc) - Infrastructure: Should DMSC contribute to infrastructure with Jenkins slaves, storage, etc? - Wider collaboration: non-ESS specific contributions from ESS developers (maintenance tasks, general documentation) - Meetings and other interaction: - ESS ECP workshop - interesting for participation from FRMII? - Frequency of meetings with NICOS team at FRMII (video, in person)
