Software Environment structure
- The replay codes are stored on one of the aonl machines under a-onl account
- The directory containing the software codes
/adaqfs/home/a-onl/gmp/He3H3/replay
- Environment variables and aliases are set in
/adaqfs/home/a-onl/.bashrc
Getting the raw data files from the repository
- data (raw files) is written to tapes and stored in the Mass Storage tape Silo (MSS) which for gmp is in /mss/halla/gmp12/raw/
- to draw a data file from the repo, login to the farm
ssh username@ifarm
and then ask for the file
jcache submit default /mss/halla/gmp12/raw/gmp_20314.dat.0 > Your request is submitted. Use id '4678425' to check the status
this procedure may take a few minutes
- raw files will be now stored for several days in /cache/mss/halla/gmp12/raw/
Running online analysis
(Last update 02/24/15)
- The files replay procedure (raw files cooking) is directed to acquire the files from /cache/mss/halla/gmp12/raw/
- Login as a-onl on one of the analysis machines (aonl1, aonl2 or aonl3) e.g.
ssh a-onl@aonl1
- passwords are written on the white board in the counting house
- to go to the online analysis directory type
He3H3goonlana
this will take you to the replay directory (/adaqfs/home/a-onl/gmp/He3H3/replay) and set the database properly.

- answer any questions, if needed
- exit analyzer
.q
- For RHRS, at the terminal, use
.x replay_R.C(run_number) (for right arm it is >= 20000)
A cooked file (replayed) will now appear in /adaqfs/home/a-onl/gmp/He3H3/replay
How to look at the online histograms?
- For LHRS, at the terminal, do
onlineLHRS #run_number#
- For RHRS
onlineRHRS #run_number#
