Summary of CERN and GSI collaborative developments

In terms of hardware development

• The  WR has been a collaboration between CO and GSI before the K agreement, and we did not change anything when the collaboration agreement came about:
  • GSI benefits from CERN's work in the core components of WR (e.g. the switch and the WR PTP Core)
  • CERN benefits from GSI's deployments in a real-life timing system, where they identify issues and work with us on fixing them and validating the solutions
    • GSI's experience in big WR deployments for GMT will be very interesting for BE-CO in the near future, as we approach that stage. Also some of the tools they have developed for operation and monitoring will be very useful.

In terms of software collaborative development between CERN and GSI

• The FESA framework
• The Device Server Framework (DSF) 
• The CMW middleware framework
• The LSA settings management, where both institutes have solid settings management systems based on the same foundations

• Despite a lot of effort, the code bases continue to diverge due to different operating concepts and machine schedules between the two institutes
• We still benefit from the work of each other (ex. adaptations to third-party libraries modifications, some non-major modifications)

            • There is a regular weekly teleconference and exchange of knowledge between the two teams which is considered useful, though it could perhaps become monthly

            • Looking to the future, there are no more collaborative developments planned at this time
