[Halld-jlab] Tasks in the hall

[Elliott Wolin]

Hi Fernando,

As you may recall, we are planning a second online data challenge for 
some time after 1-Dec.  I am currently putting together a Fasttrack-like 
schedule of what needs to be done prior to the test with timelines and 
dependencies.  If things won't be ready by 1-Dec we'll push back the 
start date of the challenge.

I'll have much more details later, see 
https://halldweb1.jlab.org/wiki/index.php/Dec_Online_Data_Challenge_2013 
for early planning documents.

Briefly:

1)  Test full data stream from front-end crates through tape silo, 
including L3 rejection and pre- and post-L3 monitoring, automated data 
transfer to silo, full CODA3 including run control and farm control 
manager, use latest FADC250 and F1TDC firmware implementing Dave A's 
proposal for data format.  Part of the test will involve reading out 
front-end modules triggered by a random pulser via the TS, TI and SD.  
The CTP, SSP, GTP system will not be used.  Another part will involve 
injecting monte-carlo data into the front-end ROC's for transfer as if 
the data had been read out from the front-end modules.

2) High priority for the Online group, this tests most of the full DAQ 
chain that will be used in production running.  I understand DOE has 
requested such a demonstration in the hall.   Not tested at that time 
include auxiliary scripts, automated bookkeeping, alarm system and other 
things not essential for just moving data.  We will use as many crates 
as are available, probably 12 is a reasonable minimum. I'm hoping both 
the FCAL and BCAL systems will have power and trigger connections to the TS.

3) Goal is to start in early Dec, depending on hardware availability.  
I'm thinking the test should take less than a week, maybe just a few 
days.  It can be interrupted at any time and resumed quickly if e.g. 
power goes off in the hall for an afternoon.

I'll have more details when I fill in the schedule and get updated 
information on hardware completion dates from various people.

I agree, no powering any crates until you give the ok!
