Hi all,

Notes from today’s meeting:

1) extended version of EuroMPI 2017 "Performance Planning" paper for journal special issue

[Dan] add state-machine diagram and various sentences throughout section 3 - emphasise life-cycle difference between blocking/nonblocking cache (must be tied to comm) and persistent cache (can be tied to request).

[Puri] change format of paper to Elsevier journal layout

[Puri] update CG example to one that gave good results

[Srinivas] integrate the reference implementation of persistent collectives into MLSL and run a machine learning application use-case - add plot (if possible) and text to paper in results section - focus on correctness/more-natural programming style, i.e. lack of need to duplicate comm per collective to avoid ordering issues

2) further implementation/optimisation work, aiming at new paper (possible target SC18)

[Dan] scope out and begin coding work on infrastructure improvement, initially for MPI_Allreduce_init

[Puri] code review and testing of PNBC new code

Next meeting: Wed 1st Nov 2017 8am Central US via GoToMeeting.
