[Mpi3-tools] TelCon 9/20 cancelled

[Marc-André Hermanns]

Hi Martin,

during the discussion of the one-sided communication chapter at Stuttgart, it was also discussed to disable the profiling interface from the command line. The reason for that (as I understood it) was that some of the new functionality might be very sensitive to additional latency, and some operations might also be able to be handled by single or few processor instructions. The feeling there was to enable implementations to use macros where applicable.

As I understand this, the prominent idea on how to handle this is to have a compile-time flag to 'mpicc' which will choose the correct implementation (w/ or w/o PMPI). However, currently not even the name of the wrapper is explicitly specified, let alone a specific option.

As this effects the profiling functionality, I think we should also discuss this here, and come up with a solution that is described somewhere in this chapter. What do you think?

Cheers,
Marc-Andre
