sPHENIX discussion of software

[pinkenburg <pinkenburg AT bnl.gov>]

Hi folks,

we will soon upgrade the PHENIX part of rcf to SL7. I compiled all our 
3rd party software under SL7 and upgraded those packages to the latest 
versions. Testing with single particle simulations gives almost 
identical results - the differences are small, in line what I see when 
running the same SL6 libraries under SL6 and SL7 (the dark art of 
floating point ops). If you need identical results you need to run the 
SL6 libs inside a singularity container which we have available.

We have two interactive machines (phnxel71, phnxel72) you can use for 
your own testing and development. Please give this (and your code) a 
spin to see if I have forgotten a package or something stopped to work 
(we have a new fastjet version, a new pythia 8 version, new lhapdf6,...).

Just to give you a heads up - there is a real move towards root6 (e.g. 
the newest genfit sources require root 6) and we will probably have to 
migrate in the near future,

Chris
