sPHENIX discussion of software

[pinkenburg <pinkenburg AT bnl.gov>]

Hi folks,

so far we have been using PHENIX accounts, anatrain for large simulation 
projects and phnxreco for our data disks. That worked okay but it had 
some nasty side effects in terms of file permissions where some 
files/directories were owned by rhphenix (the PHENIX group id) and 
became inaccessible to sPHENIX accounts (and STAR accounts with sphenix 
as secondary group id).

We now have an sphenix group account (sphnxpro) which can run the large 
scale simulation projects (it has its own quota in condor which was the 
reason we used the anatrain account). In order to make file accessible 
to everyone again we will change the ownership of all files and 
directories on /sphenix/sim/sim01 (and 02) and /sphenix/data/data01 (and 
02) to this account. This will make the management of these filesystems 
a lot easier but it will also limit the use of these filesystems as 
"private storage for stuff". I want to get these filesystems back to 
their initially intended use (storing of simulation production output 
and test beam raw data/reconstructed output).

As alternative for user storage, we do have /sphenix/user for everyone 
to use as well as the ability to create subsystem and topical group 
specific filesystems (that proposal did not get any traction but it's 
still on the table).

For users who run large scale productions which we have done in the past 
or organize the test beam productions - we would add their key to this 
account (instead of anatrain/phnxreco).

It still needs a bit of thinking how to get the test beam data from 
fermi lab over. Group accounts are not accessible on the gateways, so we 
cannot use them to push data into rcf (from inside BNL you can use rcf3 
as bridge between campus and rcf).
