New Action Items from this Meeting

Minutes

Attendees: Elliott W, Simon T, Beni Z, Dave A, Carl T, William G, Dave L, Bryan M, Yi Q, Alex S.


Emerson Technical Sales personnel visit

  • Emerson purchased the division of Motorolla that supplied VME single board processors.
  • They continue to design new PPC boards and have just introduced an Intel-based board (Core i7).
  • All boards run Linux and VxWorks. The Intel-based boards can run Windows (sorry, Beni...).
  • Dave Abbott wants to move everyone to Intel-based boards, although VxWorks will be around for a while.
  • Dave will purchase Emerson, GE-Fanuc and other boards, test them, and make recommendations to the halls.
  • Full order from JLab for 12 GeV will be large, perhaps as many as 150 boards (maybe more!).
  • Order will involve staged delivery and payment, back-end loaded as much as possible.
  • Hall D needs around 70 boards, maybe more for spares and test setups.
  • Hall D owns two GE-Fanuc boards; one is at IU and Dave has the other (for software development).
  • Embedded processors use less power, but are less powerful.
  • Emerson expects seven year processor family lifetime from Intel.
  • New boards have lots of on-board memory, can boot from local memory instead of network if desired.


cMsg Tunnels

  • Carl reported that ssh tunnels now work with cMsg.
  • He had to modify the internal protocol to accommodate tunnels, so latest version is NOT backwards compatible.
  • Dave L will test with RootSpy.


JANA/CLARA

  • JANA is the Hall D reconstruction/analysis framework (author Dave Lawrence).
  • CLARA is the Hall B service-oriented architecture framework (author Vardan Gyurjyan).
  • Hall B is considering using JANA, and Hall D is considering using CLARA.
  • Possible CLARA applications for Hall D are in the online monitoring farm and to distribute calibration constants, the B field, etc.
  • Dave and Elliott will investigate how well CLARA can work with JANA.


DANAEVIO

  • Elliott is almost done with serializing DANA objects into an EVIO file (everything is checked in).
  • Currently 19 DANA objects are converted, including object id's and associated objects.
  • Elliott will add additional DANA objects as needed (not difficult).
  • Default EVIO tag/num dictionary provided, user can override if desired.
  • Last thing to do on DANA->EVIO is addition of bank of strings, currently not supported in EVIO. Elliott will add this to EVIO and finish DANAEVIO in the next week or so.
  • Next big step is to read EVIO file and fill DANA objects. Dave L will work on this with help from Elliott.


Trigger Test Stand

  • Alex reported on the latest progress in the trigger test stand.
  • Hai is almost done programming the FPGA to allow loading of test pulse height data to test trigger algorithms ("flash replay mode").
  • Dave A will provide libraries to allow access to the new FPGA features.
  • One constraint is that all 16 channels use the same fake data.
