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
