Minutes:

• INDRA lab
  • VTP
    • FPGA TCP stack being improved, however the current firmware has a limited control over TCP/IP configuration.
    • For the resource utilization studies software source is used (contains real hardware payloads).
  • SAMPA
    • Ed sent Vardan detailed instructions how to operate the SAMPA setup.
    • Vardan started the readout and record data from 5 front-end cards in 10 separate files (2 stream per card).
• Data Lake
  • Reported a problem increasing the depth of the data lake. Chris is working on it.
• Data format
  • David described EVIO based streaming data format.
  • EVIO-6 data format was proposed to use as a streaming data format, with safely ignoring "index array" and "user header" sections of the data-format.
  • Carl will setup a meting with Hall-B to discuss if this change will affect them ( note that Hall-B is not yet switched using EVIO-6 as their off-line data format).
