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

CMS -- Please set "no new tasks"
Hi to all CMS-ers. We need to drain the job queue so that a new version of the WMAgent can be installed.
Can you please set No New Tasks so that your current tasks can run out and no new jobs start? If you have any tasks waiting to run, please suspend or abort them.
Thanks, I'll let you know as soon as the change is done.
