CMS@Home disruption this week
It appears that a database intervention at CERN went badly, leaving our data tables empty and us not being able to submit new CMS@Home jobs. Advice is that it will take several days to recover -- and as well as that some of the major players are in the USA, which has holidays for the rest of this week. I'll keep an eye on it, but I'm doubtful we'll be running again this week. Sorry 'bout that!

CMS job shortage Wednesday 13th November
CMS IT will be installing a new version of WMAgent on Wednesday. This will impact job availability for the duration of the intervention. We might be able to eliminate the little gremlin that's been plaguing us for the last few weeks, too.
So, please set your CMS processors to No New Tasks sometime tomorrow, Tuesday 12th, so that current tasks will stop requesting new jobs before the queues get cut. I'll let you know when jobs are available again.

Using a local proxy to reduce network traffic for CMS
Thanks to computezrmle, with additional work from Laurence and a couple of CMS experts (and my adding one line to the site-local-config file) there is now a way to set up a local caching proxy to greatly reduce your network traffic. Each job instance that runs within s CMS BOINC task must retrieve a lot of set-up data from our database. This data doesn't change very often, so if you keep a local copy the job can access that rather than going over the network every time.
Instructions on how to do this are available at https://lhcathomedev.cern.ch/lhcathome-dev/forum_thread.phpp?id=475&postid=6396 or https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5052&postid=39072
