Project status report [Gianluca Petrillo]

reminder: OSX distribution is not fully supported, and it won't be until we can build it with Clang (c2 qualifier)
also reminder: forward compatibility (using an old art version to read a file produced by a newer art version) is not supported
- [Thomas Junk] shouldn't an exception be thrown when such an attempt is made? [Lynn Garren] there was some discussion among art stakeholders about that...

still needed sign off for new version of GENIE (2.12.10) by some of LArSoft stakeholders

we have proposed a migration plan to deploy future software into /cvmfs/larsoft.opensciencegrid.org
this will eventually replace /grid/fermiapp/products/larsoft too
we will proceed cautiously
- Jenkins build node issues have to be addressed before we can fully turn to the new area for everything
- things will not be removed from the common Fermilab area
- [Gianluca Petrillo] will things like sam_web_client be also in the new area? [A] Only LArSoft-distributed UPS products will be in the new area; the common Fermilab area will still be needed for the rest

be aware of this, start testing the new area, and make any issues official, either via Redmine issue or e-mail to larsoft-team@fnal.gov

looking for a target simple enough to be dealt with, heavy enough that the optimisation can improve it, and popular enough that users can actually benefit from this work
considered detector digitisation
- the Fastest Fourier Transform in the West library, which takes a good deal of the processing time, might be already optimised though, and anyway we don't have control of its source
now considering Projection Matching Algorithm

Postponed.
