Login on LN computer
The LN computer lives in the GRETINA net and since December 2015 it is accessible from NSCL network
login on gateway machine nsclgw1.nscl.msu.edu
login as ln on gretina-gln1.nscl.msu.edu (35.8.35.167)
Remember: “liquid nitrogen two for gretina”
from a1/a2: ln@gln1
LN scripts
They are found in ~/scripts. The main LN program (gln_master) is a job
run by root and not directly accessible by the user. Interactions happen
via scripts. Most interesting is run-gln-ui.sh, the User Interface.
run-gln-ui.sh: User Interface, 'help' gives option
run-send-alarm.sh: Add your email here for receiving alarms
run-log.sh: Add your email here for receiving logs
run-log2.sh: Add your email here for receiving logs after each fill
run-log3.sh:
run-send-alarm-wd.sh
finish_fill.sh: script executed after fill attempt
run-gln-master.sh
run-mail-que-view.sh
run-time-sync.sh
run-backup.sh
run-tlog-and-plot.sh
run-dlog-and-plot.sh
run-mail-que-flush.sh
run-view-master.sh: Output of the LN master process
Making long term T plots:
on gln machine go to ~/other/thistory-dev
run there ./run-thistory.sh XXX with the last day as input parameter
results th.pdf and d.pdf are written in ~/plots
uncomment/comment different templates in script for covering different time ranges
LN configuration
The LN configuration file is found as ~/gln/gln.fig. It is self-explanatory. If this file got updated, use run-gln-ui.sh script and the command “load” in there. Note: After a “load” in the UI all detector fill schedules are gone! You need to do a “ton x y z …” or “fill x y z after h:mm”.
