Draining the CMS job queue
Because of an upgrade to the WMAgent server, we need to drain the CMS job queue. So, I'm not submitting any more batches at present and we should start running out over the weekend. If you see that you are not getting any CMS jobs (not tasks...) please set No New Jobs or stop BOINC.
I expect that the intervention will take place Monday morning, and hopefully we'll have new jobs again later that day.

Good news for the CMS@Home application
This afternoon we demonstrated the final link in the chain of producing Monte Carlo data for CMS using this project (and the -dev project too, of course), namely the transfer of result files from the temporary Data Bridge storage to a CMS Tier 2 site's storage element (SE). To summarise, the steps are:

o Creating a configuration script defining the process(es) to be simulated
o Submitting a batch of jobs of duration and result-file size suitable for running by volunteers
o Having those jobs picked up by volunteers running BOINC and the CMS@Home application, and the result files returned to the Data Bridge
o Running "merge" jobs on a small cluster at CERN to collect the smaller files into larger files (~2.2 GB) -- this step has to be done at CERN as most volunteers will not have the bandwidth (or data plan!) to handle the data volumes required. This step also serves to a large extent as the verification step required to satisfy CMS of the result files' integrity.
o Transferring the merged files into the Grid environment where they are then readily available to CMS researchers around the world

Thanks, everybody. From here on it gets more political, but we've been garnering support as the project progressed. We now need to move into a more "production" environment and convince central powers-that-be to take over the responsibility of submitting suitable workflows and collecting the results. You will still see some changes in the future, especially as we bring some of the more-advanced features across here from the -dev project.

Please report to me eric.mcintosh@cern.ch,
or to the Topic Sixtrack Application, MacOS executable thread,

VM applications broken by the Windows 10 update KB3206632
The Windows 10 update KB3206632 introduces an issue that affects virtualization-based security (VBS) and hence may break VM applications. The issue is fixed in the update KB3213522. If you are running Windows 10, please ensure that you have applied the KB3213522 update.

Thanks everyone who contributed the treads on this issue.

Season's Greetings
A very Merry Christmas and a Happy New Year to all the LHC@home supporters.
(I shall send some news about our plans for 2017 in the next few days.)
