the data that I have from my Git commit trawling script (which may not be identical to Peter's since he uses data from Dustin) shows the following for 2.12.50..2.13.50 (essentially all the commits after the end of 2.12 development until the start of 2.13 development).

Note that James Simmons' contributions are split between "infradead.org<http://infradead.org>" and "yahoo.com<http://yahoo.com>" in this list since he does not use an "@ornl.gov" email address for his contributions.  My script also does not count code reviews on patches like Peter's does.

Thanks, Peter.  I think you might be right that ORNL is just covered up on the left hand graphic (LoC).  For clarity, could you just tell us what the ORNL LoC contribution was for 2.13.0?

Great that you have the NoC data already.  Since you already have that data for 2.13.0, would you mind sharing it with the list too?

   Re James - yes he has consistently been one of the top contributors in any measurement for a number of years. ORNL appears on the right hand graphic and I think that the label is just covered by another label on the left hand graphic - the formatting of those labels is very fiddly. The scripts run to extract this data do also generate NOC and I have shown that data as well in the past but I condensed due to wanting to cover other topics in limited space. I hope that James will forgive me this oversight!

       Hi, Ken.  Thanks for sharing these.

       Peter, I have a question and a comment/suggestion for you about the "Lustre 2.13 Contributions" pie charts.  For the LINES OF CODE contributors, I don't see ORNL.  I've got to figure that there must be some oversight.  I'm sure that James Simmons alone contributed many things to 2.13.  Surely, enough to break out of the "Other" category all on his own, right?  Then, maybe just a helpful suggestion: at the next update could you please also tell us about `# of commits` (per organization)?  I tend to think that commit count is more often a more useful metric than LOC.

           Hi Thomas,

           An aggregated version of the slides is available at:


           There were some challenges combining them in a way that works in all PDF viewers. If there are any issues with rendering, please let me know and we can make the individual decks available as well.



           Are the slides presented during the bof in Denver available somewhere?

           I'm specifically looking for one of the sites presentation that gave some feedback about DoM.
