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 (https://lhcathomedev.cern.ch/lhcathome-dev/forum_thread.php?id=475&postid=6396) or https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5052&postid=39072
