SUMMARY:Modes, Persistence and Orthogonality: Blowing MPI Up
DESCRIPTION:Jesper Larsson Träff, Ioannis Vardas, and Sascha Hunold (Techn
 ical University of Vienna)\n\nThe MPI specification provides a restricted 
 form of persistence in point-to-point and collective communication operati
 ons that purportedly enables libraries to amortize precomputation and setu
 p costs over longer sequences of identical communication operations. Becau
 se of the way that MPI has chosen to represent semantics and modes of comm
 unication, further additions and modifications to the MPI specification of
 ten came and come at the cost of a (combinatorial) blow-up in the number o
 f interface functions. \n\nWe discuss how to exploit orthogonality and sep
 aration of concerns more thoroughly to prevent the proliferation of concre
 te interface functions while still providing essentially the same persiste
 nce as current MPI and without any additional burden on library implemente
 rs. We introduce new variants of persistence, which we call pairwise and r
 elaxed persistence. Our concrete proposals contribute to the discussion ab
 out why MPI is so huge and what could or should be done about that.\n\nTag
