Developer's meeting
→
Europe/Zurich
present: Milo, Enrico, Roland, Frank
EHN1:
- 100 Gbps Mellanox card (with both links) now working in FELIX host, following BIOS and other changes to the host's power management
- Joern Schumacher (ATLAS FELIX) is also testing the ConnectX-5 card, even if with different motherboards (SuperMicro) than the Dell one used in srv19; it will be useful to keep in touch about optimisation
- longish discussion about power management: Enrico will continuing testing, still with internal data generation but sending out data on both links simultaneously, to stress the system
- the FELIX card is expected to consume some 70W; the ConnectX-5 card up to 125W; so a priori this is not expected to be a problem for the present 750W power supply (but a more powerful PS can be bought, if needed)
- waiting for Dan to get around to fixing WIB-FELIX firmware issues
- hopefully this can be soon, given that the WIB-RCE firmware issues have apparently been sorted out, and most issues are expected to be in common
CHEP abstract:
- not submitted yet, waiting for information on any DUNE guidance on such ProtoDUNE conference contributions (but will need to submit by next Monday)
- also still need to converge on author list (preference for now is to stick with CERN/Nikhef/PNNL)
Next meeting:
- tentatively planned for January 24
- we agreed to move the nominal starting time for future meetings back from 18:00 to 17:00 (we can still decide to start at 18:00 whenever the earlier time is problematic)
