Hello Mark and all,

After a number of interruptions, I finally finished the roll-out of a 
container-based osg production framework for Gluex simulations. Please 
have a look at the git project linked below. It contains two scripts 
that give everything you need to try it. This is bound to be somewhat 
rough at first, but let me know how it goes.


The sim-recon build that is configured for osg production right now is 
based on version.2.11.xml from the http://halldweb.jlab.org/dist area, 
which looks like the latest stable release. Still, it is not very 
stable. This is probably because of the fast development over the past 
few months of calibrations for real data, and the lack of corresponding 
exercising of the code on Monte Carlo. A minimal checkout and run of the 
distro job script submits a job with 40 slices of 250 events each 
generated with bggen, simulated with hdgeant4, passed through hd_root 
for REST production, and through hd_root again for plugins analysis. 
When I tested it, only one of the 40 jobs crashed:

*** Error in `hd_root': free(): invalid pointer: 0x00002baa1c394ff8 ***

with 37 completing successfully, and 2 others bombing out of hd_root for 
other reasons. At this point, I would like to pass things back to the 
reconstruction/analysis gurus. I could work on diagnosing and fixing 
these bugs, but as I discovered with the "hd_root hanging" bug last 
week, there is a good chance that some of these bugs are known and fixed 
in somedev dev branch of the sim_recon tree or jana repo.

Please have a look and try things out. Let me know if/when you run into 
issues. I will update the HOWTO on the wiki once we get a little further 
into the learning curve. Right now, you can rely on the README in the 
git project linked above for docs.
