<p>Hi everyone, <br>
</p>
<p>Looks like the JLab compute environment has a new release to
version 2.0, this includes the change to ROOT 6 (note that our
g4sbs is already compatible with the ROOT and GEANT4 versions in
the new release). The good news is that if you already migrated to
ROOT 6 on your local machine, you will be able to analyze g4sbs
output data produced on the JLab batch farm using ROOT 6 on your
local machine. There is a compatibility issue in g4sbs with
respect to the "G4SBSRunData" object that stores the simulation
meta-data; as far as I can tell, ROOT 6 cannot read the metadata
in root files produced by g4sbs executables that were built
against ROOT version 5 and vice versa. The ROOT trees do not seem
to present any problems. The release of ROOT version 6 into the
"production" computing environment on the JLab batch farm means
that if you are working with g4sbs, it would make sense at this
time to update to ROOT version 6 on any and all machines you are
using to run simulations and/or analyze their output. <br>
</p>
<p>I will test building g4sbs in the new production environment and
update the g4sbs documentation page accordingly. <br>
</p>
<p>Sincerely,</p>
<p>Andrew<br>

<pre>Dear Users,
Please see the information from Mauri Ungaro about new versions of physics software for the data analysis cluster, especially since the new farm16 Broadwell compute nodes are ready for use! Note the November 22 date for requiring a production.csh version argument.
Regards,
Sandy
--------
A new version of the JLab software libraries is available.
This release adopts two critical changes:
- ROOT v6
- c++11 compiler: gcc 5.2
Because of this, it is a "major" release: 2.0
Version 2.0 includes these updates:
- clhep: 2.2.0.8 > 2.3.3.1
- QT: 5.3.2 > 5.6.0
- xercesc: 3.1.1 > 3.1.3
- geant4: 4.10.01.p03 > 4.10.02.p02
- gemc: 2.4 > 2.5
- JANA: stays 0.7.4p2
- banks: 1,2 > 1.3
- build system: 1.3 > 1.4
- ROOT: 5.34.34 > 6.06
- EVIO: 4.4.4 > 5.1
- CCDB: stays 1.06
The "production.csh" will require the version argument starting from Tuesday, Nov 22. This will ensure that:
- changes in JLAB_VERSION will not change libraries version underneath users
- there's no ambiguity in what a version users are running.
Details on what's in each version can be found here.
To setup the environment. Csh users:
source /site/12gev_phys/production.csh 2.0
Bash users:
source /site/12gev_phys/2.0/ce/jlab.sh
