Agenda

General Updates

  • BOF Files
    • c1500x4096 mode still has many timing errors but Randy is getting some tips from Dave
    • Randy discovered an error in c1500x1024 mode regarding the alignment between input and out blocks and is working on a fix
    • We have agreement that Vereese will help but nothing formal has been arranged yet
  • Software
    • We had significant discussion about how to handle the BL coherent modes
      • Currently, the roach on Bank A acts as masters and sends data for processing on the eight VEGAS HPCs
      • BL will want to expand this so that each current roach controls its own set of eight HPCs
      • We plan on having the Coordinator take care of communicating to all of the relevant managers, which will run on each HPC
      • We propose a new naming scheme, where each master bank (the one with a roach) is indexed with 0 and the HPCs it controls are indexed with 1 - 7
        • For example, when in coherent mode the current Bank A becomes Bank A0 and controls HPC processes on itself and Banks A1 - A7. This would be true for Bank B0 - B7, C0 - C7, etc.
      • We will need to expand mode definitions as currently the mode section in the vegas.conf file can only designate one bank to act as master
    • Jason and Randy verified that BOF files have switching signal blocks, so the manager will need to set up the switching signal

Date / Time of Next Meeting
