simulations progress at regina
Simulations Progress at Regina
  • Event generation with genr8 – output in ascii format
  • Conversion to either HDFast input (stdhep) or HDGeant input (hddm)
  • HDFast simulation – creation of ROOT data tree
  • HDGeant simulation – creation of hddm hit information
  • Converstion of HDGeant hddm file to xml format (hddm-xml)

First scripts to parse xml data files to extract BCAL hit info

First code to create BCAL ntuples for Paw++ analysis

other useful things
Other Useful Things
  • Script to install Hall D software (genr8, HDFast, HDGeant, conversion scripts, xerces-c libraries, etc.) from tar files and CVS repository at Jlab
  • Designed for RH7.X systems. Easy to modify for RH6.X systems.
  • Script to do HDGeant simulation “start-to-finish” beginning with genr8 input file, and specifying number of events to simulate
multiple platform support
Multiple Platform Support
  • All software (that I know of) works on RH6.X and RH7.X. Installation is fairly automated.
  • All software (that I know of) works under Tru64 Unix. Requires compiling of all source code locally. CERN libraries are commonly available.
  • Most things work under AlphaLinux. HDGeant has problems, due to CERN library difficulties .
  • Tru64 binaries compiled statically run under AlphaLinux. No significant performance hit.
online software
Online Software
  • Data Acquisition – to CODA or not to CODA?
  • Elliot has been working on tools to view CODA data. What XML viewing/parsing tools are available?
  • Event decoding software – who will write this? We should ensure some type of compatibility with HDDM, yes?
  • Modular or monolithic format? Learning curve may be too steep for entirely modular format.
code management
Code management
  • Is CVS adequate? If it is, then should we establish some sort of protocol for code management? What standards should we have for checking in new code?
    • Compile check only?
    • Compile and run test file on one system?
    • Compile and run test file on multiple platforms?
  • Do we need a human librarian?
  • What other options are available?
analysis code
Analysis Code
  • Personally, I am for it.
  • What is the current status of code which reads XML/HDDM hits data and does something useful with it?
  • Can we make use of software which already exists?
    • Code which really already exists from other detectors?
    • Code which might need only small mods?
    • Canned code?
