Configuration files for decompostion
The configuration for the decomposition is here: https://wikihost.nscl.msu.edu/gretina/doku.php/daq:decomp
Positioning of the quads
When a position of a detector is changed the following has to be updated:
- CS_GblId in /global/devel/boot/vmeArray/vme*.cmd — The Id is given by hole_number * 16 + position_in_quad * 4 + board_number
- GTSort_shack/DetNum.dat — self explanatory
How to replace a broken node with a spare one
To replace a node of the cluster (e.g. n000x) with a spare one (e.g. n000y) follow the following procedure: In the file /global/devel/gretTop/11-1/gretClust/bin/linux-x86/setup7modulesRaw.sh and in the file /global/devel/gretTop/11-1/gretClust/bin/linux-x86/setupEndtoEnd28.sh
- replace node000x_CS_Program? with node000y_CS_Program?
- from the “GRETINA CLUSTER node allocation” window identify the name of the Decomp process (middle click on the crystal number) and replace it in the files
- change the n000x to offline and the n000y to online using the variables Decomp???_CS_Enable
DAQ cold restart
- Switch off all the vme crates.
- wait 30 s
- Switch on the vme crate of the trigger cards.
- wait till the red lights over the trigger board are on (~ 3 minutes)
- Switch on all the other vme crates
- wait till the green blinking lights appears on all the digitizers (~ 3 minutes)
- start the daq and check the synchronization (alarm window or TS window). If few of the digitizers are out of sync recover them using the “reboot IOCs button”, otherwise power-cycle on their crate
