NEWS:
Shutdown will start on June 3rd for 2 weeks as planned.
SYSTEM:
Steve said since virus scan priority was lowered, iFIX system functions
much better - thanks to Chris Brew at the CD who found out the way to lower
priority somehow.
During the virus scan we used to see about 10 to 20 systmes went
to gray on 'CDFGbAlarms' page. After the change we see ony about 2 systems
went to gray.
Steve pointed out that the TOF takes about 2 times longer than other systems
(~1hr) to complete virus scan. He thinks this has to do with 100% usage of
CPU time. He said the CLC1 improved substantially since we cut down the cpu
usage.
He also mentioned that someone accidentally killed the virus scan excutable
in Muon3. We will restart it during the shutdown.
We also learned that turning off real time virus scan made little impact
in performance.
VNODE:
Ace account time out (every 12 hr) problem caused a lot of trouble during
the memorial weekend. It turned out someone thought it was operator and
put in the time out limit.
The Sunday morning power outage made things worse. We need a better
instruction to recover from power outage. There are too many post-it
stickers around the Vnode screens.
ICICLE:
Bill said a summer student ( Ravine Pierre ) is working on a software
project. He will be writing a module which can store iFIX information
into data stream. This will be very convenient for remote institutions.
Margherita is working to integrate the Muon Scintillators into the Icicle.
She also mentioned that Icicle runs much more reliably since the virus scan
priority has been lowered.
PSM:
Marcin removed the confusing check boxes and replaced them with small squares
in the PSM pictures.
MUON:
