CHEP Abstract due December 31st so really before christmas vacation and we ought to start working on them soon.

Meeting this week: POW on Wednesday.  

Vectorization: Covered by PPP/Danilo.

Math: Lorenzo circulate something tomorrow

Shift: Pere not attending.  Enric next.   
Amadio: Looking at pull request we have several open things that are not going anywhere for several months.  What should we do about them?  Maybe close them and request the developer to re-open a new one?

Failing test are increasing: Is it infrastructure?

Amadio: Fixing classic build and icc.

Philippe: Need to look at merging enums decls.  Vassil, can you check?

Branch 6.12: still outstanding issue.  Nightly used the wrong version of roottest.

Lorenzo: TMVA integration of neural network GSCO PR.  Working on optimizing CPU performance and parallelization.  

Guilherme: Trying to fix things for v6.12 and preparing for Wednesday.

Oksana; Working on visualization part and modernization.

Xavi: working on new executor.  Added Numa executor proposal.  Applying suggestion from last PPP and redoing timing.

Raphael: Got boost running over the week-end, fixing module in CMS.  rootmap file seems to still cause problem including recursive parsing.   Autoloading of namespace is no problem.   But at this point we should really be stepping back and figuring out if there is a way to replace rootmap file with module without performance degradation (memory and cpu).

Vassil: After a few tweaks, I am able to get to the point where rootmap replaced by module is the same start up time, I still have to check the memory cost.  Still some failures but I am very hopeful that we can converge.

Omar: TMVA class classification.

Gerri: PR on hist merging was merged.  Preparing for POW meeting.  Looking for machines.  For containers there are still a few issue to be looked into, in particular large images (possibly solved by storing images in CVMFS).

Jakob: Getting familiar with TTree and TFile and their v7 counterpart.

Amadio: The GPU I have won is almost there, possible hic-up with tax.

There are minutes attached to this event. Show them.
