All of our WN are now upgraded to a kernel rpm set (862.11.6 and 862.14.4) that addresses the "Foreshadow" hardware bug.  There were a number of problems with this upgrade path, as the first time through we had massive numbers of score WN crash on some fatal interaction between HTCondor, cvmfs and the kernel.  Jakob produced a nightly build of 2.5.2 (818) that addressed issues that he found, and we down-graded to HTCondor 8.4.11 (that we had been running) from 8.6.12, but what seemed to really help was the addition of the sl-fastbugs repo in these SL7 WN.  In fact, the most recent OSG cvmfs release required an rpm that was found only in sl-fastbugs.  All of our WN now seem reasonably stable.  We are working with Brian Lin to further understand issues.

We will likely upgrade dCache from version 4.2.6 to 4.2.14 within the next week. 

Last week we retired a shelf of 2TB disks to use as spares for similar systems.  I will soon be updating the Normalization Factors spread sheet and other locations to reflect this change.

We are currently working with Dell to finalize hardware purchases with our current funds.  These are mostly compute hardware, with an admixture of needed support systems such as PDUs and possibly switches.  Details should be finalized within the next week or two.

On September 3, Production SAM tests to AGLT2 began to fail when an extra, previously unexpected 'queue' value began to arrive with the HTCondor job.  This was noted in the September WLCG report, and subsequently corrected when the cause was found around October 11.

This is my last Computing Integration and Operations meeting that I will attend, as my (Bob) retirement is effective on November 1.  I wish everyone the best, always, with ATLAS and your life.  It has been a pleasure to work with you all over the years.
