✅ Action items
James Walder to schedule a ‘hackathon’ within a F2F to have a session on architectural planning.
Katy Ellis to run (and help coordinate) additional tests on File transfer performance, to understand the differences between SVC/new network and GW / legacy network hosts that suggest different levels of performance.
These tests to involve iperf testing, and concurrent FTS-issued file transfer testing.
James Walder to prepare an outline of the expected roadmap for XRootD developments in 2024.
⤴ Decisions
- Alexander Rogovskiy to work on and help coordinate the development of a checksum library to perform metadata requests, calling the external checksum script, if a checksum is needed. This is agreed to be a stepping stone to a full implementation whereby the checksum itself may be caclulated by the checksum library.
