* '''Jana 0.7.3''': David has release a new version of Jana. Details will be coming out shortly but some highlights are:

** event numbers changed from int32 to int64 to accommodate long runs
 +
*** implementation accommodates 32-bit event numbers currently used by sim-recon

** search for associated objects done recursively, the new default, depth of search can be limited by user

** a list of all possible command line options can be generated

Sean, Justin and Mark have put in a lot of adjustments to the conditions for the simulation, mainly to correct oversights. There is now a [https://halldweb.jlab.org/detcom/02/docs/detcom_02.html web page] listing these conditions in addition to [[Spring 2015 Commissioning Simulations|Sean's original wiki page]].The system is ready to go, but we will wait a bit for new version of the CDC track finding software from Simon before we start. For now we plan not to use the new BCAL code from Tegan Beattie while it goes through validity checks by the Calorimenter Group.

===Offline Monitoring===
 +
 +
Kei summarized the state of the periodic offline monitoring jobs. See [[Media:2015-06-10-offline_monitoring.pdf|his slides]] for the complete story. He covered:
 +
* statistics for the current launch (last Friday)
 +
* a problem with the farm last weekend that delayed processing
 +
* the status of the start counter plug-in
 +
* deprecation of the 2-track skim
 +
* success/failure comparisons between the launches for the Spring data
 +
* a problem with FCAL ADC data
 +
* crashes due to an EVIO parse error
 +
* schedule for the next launch (June 19)

===Git for GlueX?===

Mark gave us his take on issues surrounding a possible transition from Subversion to Git for a source code version control system. Please see [https://halldweb.jlab.org/talks/2015/git_for_gluex.pdf his slides] to see all the bullets (they are [http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=2757 also on the DocDB]). He discussed:
 +
 +
* Conversion of reconstruction code (i. e., not everything under Subversion)
 +
* Multiple repositories in Git
 +
* Git commits: staging code before checking it in
 +
* Some common Git commands
 +
* Workflow models: how to organize the multiple repositories
 +
* Nice Git features
 +
* Extra steps in implementing and using Git
 +
* How to manage Conversion?
 +
* Why we should change

We did not make any decisions; in fact we did not event discuss a decision-making process. There are some things to work out before a change can be proposed, mainly how the group would transition to a new system without seriously impeding code development work.

Slides

Talks can be deposited in the directory /group/halld/www/halldweb/html/talks/2015 on the JLab CUE. This directory is accessible from the web at https://halldweb.jlab.org/talks/2015/ .

Minutes

Present:

  • CMU: Curtis Meyer
  • JLab: Mark Ito (chair), David Lawrence, Kei Moriya, Eric Pooser, Simon Taylor, Beni Zihlmann
  • NU: Sean Dobbs

Announcements

  • New Releases. Mark reminded us of the recent releases of HDDS and Sim-Recon as announced on the email list.
  • Jana 0.7.3: David has release a new version of Jana. Details will be coming out shortly but some highlights are:
    • event numbers changed from int32 to int64 to accommodate long runs
      • implementation accommodates 32-bit event numbers currently used by sim-recon
    • search for associated objects done recursively, the new default, depth of search can be limited by user
    • a list of all possible command line options can be generated

Spring 2015 Commissioning Simulations

Sean, Justin and Mark have put in a lot of adjustments to the conditions for the simulation, mainly to correct oversights. There is now a web page listing these conditions in addition to Sean's original wiki page.The system is ready to go, but we will wait a bit for new version of the CDC track finding software from Simon before we start. For now we plan not to use the new BCAL code from Tegan Beattie while it goes through validity checks by the Calorimenter Group.

Offline Monitoring

Kei summarized the state of the periodic offline monitoring jobs. See his slides for the complete story. He covered:

  • statistics for the current launch (last Friday)
  • a problem with the farm last weekend that delayed processing
  • the status of the start counter plug-in
  • deprecation of the 2-track skim
  • success/failure comparisons between the launches for the Spring data
  • a problem with FCAL ADC data
  • crashes due to an EVIO parse error
  • schedule for the next launch (June 19)

Git for GlueX?

Mark gave us his take on issues surrounding a possible transition from Subversion to Git for a source code version control system. Please see his slides to see all the bullets (they are also on the DocDB). He discussed:

  • Conversion of reconstruction code (i. e., not everything under Subversion)
  • Multiple repositories in Git
  • Git commits: staging code before checking it in
  • Some common Git commands
  • Workflow models: how to organize the multiple repositories
  • Nice Git features
  • Extra steps in implementing and using Git
  • How to manage Conversion?
  • Why we should change

We did not make any decisions; in fact we did not event discuss a decision-making process. There are some things to work out before a change can be proposed, mainly how the group would transition to a new system without seriously impeding code development work.
