sPHENIX HCal discussion

Dear HCal aficionados,

I tried my hand at running the whole HCal with the full run control and 
all. After a few issues, I got it.

First off, the filerules for west (seb16) and east (seb17) were the 
same. I changed this to include "East" or "West" in the file names:

>   -- defined Run Types:
>           cosmics - 
> /bbox/commissioning/HCal/cosmics/cosmics_West-%08d-%04d.prdf
>              junk - /bbox/commissioning/HCal/junk/junk_West-%08d-%04d.prdf
>               led - /bbox/commissioning/HCal/led/led_West-%08d-%04d.prdf
>         led_tower - 
> /bbox/commissioning/HCal/led_tower_by_tower_hcal/led_tower_West-%08d-%04d.prdf
>          pedestal - 
> /bbox/commissioning/HCal/pedestal/pedestal_EAST-%08d-%04d.prdf
>            pulser - /bbox/commissioning/HCal/pulser/pulser_West-%08d-%04d.prdf

so the 2 RCDAQs can log at the same time. I also changed the logfile to

> H=$(hostname)
...
> LOGFILE=$HOME/rcdaq_${H}.log

so they don't step on each other.

Since run control needs to be able to get at the participating servers 
and the GTM, wehn using gtm02 one needs to run RunControl on daq01. (We 
talked about changing yours to reside on the DAQ network soon, I didn't 
get around to it today).

I talked about this before - the way it works is that RC goes to all 
participating servers and starts a run with the same run number, sees 
that they are done and primed, and then issues the equivalent of a 
gtm_startun. On endrun, gtm_stop comes first, then ends the runs on all 
servers.

Ok, nothing is perfect; they are off by one event in the count -

> [phnxrc@seb16 HCal]$ ddump -p 10 -i -t 12 
> /bbox/commissioning/HCal/junk/junk_East-00004395-0000.prdf
>  -- Event 12344 Run:  4395 length:    16 frames:   1 type: 12 (End Run Event) 
> 1680125638
> [phnxrc@seb16 HCal]$ ddump -p 10 -i -t 12 
> /bbox/commissioning/HCal/junk/junk_West-00004395-0000.prdf
>  -- Event 12345 Run:  4395 length:    16 frames:   1 type: 12 (End Run Event) 
> 1680125638

but still a hopeful start.

Attached is a screenshot of the RunControl GUI at work, together with 
the 2 servers' rcdaq_status GUIs, for feel-good value (they are just to 
look at, they are completely passive).

Also, as we discussed, the event numbers are not synchronized, each GUI 
updates on an interval, so in this view they are all a bit different.

Best,
        Martin
