Hi Richard,<br>
<br>
Sorry, I accidentally hit some key that sent my previous e-mail
prematurely. <br>
<br>
There are a couple of ways to turn off the ticker. Programmatically,
you can just<br>
do the following anytime after the JApplication object has been
created:<br>
<br>
japp->batch_mode=true;<br>
<br>
From the command line, you can specify the JANA:BATCH_MODE
configuration<br>
parameter:<br>
<br>
-PJANA:BATCH_MODE=1<br>
<br>
<br>
Regards,<br>
-David<br>

The only way to know if we are ready is to start production and
find out what hits the fan. I pushed out a small batch this
morning just to test the framework. Things have changed on
several sites since Igor last ran on the grid (software areas
have moved, policies have changed here and there) so I am
tweaking things to get them to run everywhere, but events are
flowing. <br>
<br>
I started production this morning at 7:30 with a batch of 1000
jobs. As of 18:00 hours this afternoon all but a few stragglers
were done, and 46 million rest events (920 files of 50k events
each) have landed on the srm at UConn. Log files all look good.
It seems that the software is more robust than I feared. Not a
single job has crapped out due to memory ceiling violations so
far. None of the rest files has exactly the same size, which
means that we didn't goof up with our random numbers in the most
obvious way. <br>
<br>
I stopped production at 18:00 to implement changes in a couple
of scripts, and just launched again, this time a batch of 500
million events. That should keep the pipe full until the
weekend. Then it is time to do the real challenge -- 5 billion
events in one batch job! <br>
<br>
One small change I wish we had made is to get rid of the ticker
tape of how many events have been processed so far. This is
nice for interactive running, but in batch mode it fills up the
log file with very little purpose, and makes browsing the log
file a pain. A quick glance at JApplication did not show an
obvious way to turn it off with a command line option, so I
created a cron job that scans the log files as they come back
from the grid and compresses out the ticker tape lines. Saves
an order of magnitude in space in my log directory. <br>

I was wondering if there are any decisions left or technical
questions or concerns at this point. Otherwise I think we
can start. I'm assuming that Richard is done with the
changes to the branch and Paul thinks that they are fine.
I'll make a tag by tomorrow morning if I do not hear that
that is a bad idea. <br>
<br>
If either of you think we really do need a conference call,
let me know and I will set one up. <br>

Can we have a quick, touch-base-like phone meeting on the
data challenge <br>
status today? Say at 4 pm. Or suggest a time. We can use
the ReadyTalk <br>
thing. <br>
