Agenda:
- General status updates/Schedule review/mini-Global Runs status.
- Status of DCS and DAQ Room/Event Building
- AOB
-- Javier -- Added a “Manual Mode” to the RTF to allow triggering manual injections (stops the continuous injections, requested by Calo team). Will put together some RTF documentation and send out in next couple days. Also working on simulating Avalanche firmware functionality, making progress.
-- Eric -- Made access change to the PCIe driver to allow root access and to not lock, and been working with Giani to get full rate including with DQM at Sidet.
-- Giani -- Working on Sidet test stand with Calo team and Eric/Ron. Focusing on DQM configuration at the moment. Achieved 10KHz event rate (data rate at DL at 60MBps+) through Board Read → Event Builder → Data Logger.
-- Ron -- Helping Giani/Eric with stability/rate tests. Also considering system interference (from admin/monitoring software)
-- Glenn -- DCS EPICS processes in DAQ room seem to have started up well after recent power outage. Still need PV alarm limit values. Thinking about extra power usage of CRV ROCs, keep in mind for extra DAQ room and Detector Hall heat load.
-- Craig -- Leading CRV strategy is to redo FEB2 for PoE++, and try to retrofit present ROCs.
-- Antonio -- Working with Calo team to configure EPICS/Archiver for Sidet (testing LV/HV supplies). Also have been discussing with Merrill to start alarm system for Calorimeter. Elenor working on PHEOBUS page for Calorimeter. And also considering mirroring progress in DAQ room. There is an instance of EPICS/Archiver at Calo-01 at Sidet. Db for Sidet Archiver is daq14 db (through tunnel).
-- Ryan -- No hardware issues brought up by VSTs or HSTs; helping with some minor software bugs Giani and Luca have identified. Whild idling on hardware issues, been focusing on Hardware Event Building - plan to investigate data rates (packet drops) from DTC. Ron remembers a software TCP-based test he conducted and was able to achieve 10G line rate through the switch (remembers a 4x4 node test, round robin), UDP-based tests dropped packets in Ron’s tests. Compare stats at DTCs and at switch (with Ron’s help). Ron notes that TCP allows specifying a burst size (throtttled by ack), which is advantageous (DTCs will have to overcome).
