[mpiwg-sessions] Topics for Sessions WG meeting 27th January 2025

Fri Jan 24 04:24:06 CST 2025

Dear all,

I'll be at a workshop on Monday, hence, it's not sure whether I can 
attend this meeting.

Resonating with Dominik, I'd like to propose that we're working in the 
next months on writing down step-by-step the DPP approachin Latex as an 
extension to MPI, how it works, the rationality, etc.

We were working on this over the last years, had many discussions, 
finally also have an implementation, others also use it, etc. I think 
it's now time to try to get it into MPI.

In this way we'll structure things nicely, have some concrete discussion 
basis, etc.
Any feedback is appreciated.

@Howard, if you have some better idea, please let me know.

Cheers,

Martin
