Hi MPI-Forum, This is request to move away from the master-slave terminology currently used in the following locations in the 2019 draft specification : - section 6.4.1 : page 256, line 46 - example 6.5.3 page 272 and page 273 These would be better described by supervisor/executor or manager/worker or anything the members of "Groups, Contexts, Communicators, Caching" working group see fit. Thank You, Sajid Ali | PhD Candidate Applied Physics Northwestern University s-sajid-ali.github.io
