[mvapich-discuss] Parameters in LogGP with osu-microbenchmarks

[Subramoni, Hari]

Hi, Junchao.

Are you looking for OMB to print out the expected performance as predicted by the LogGP model along with the actual/observed latency?

Thx,
Hari.

Hello,
   I was wondering if it is possible to collect parameters in the LogGP [1] parallel computation model with osu-microbenchmarks. If not, how can I build a performance model for communication like what in MPI_Neighbor_alltoallv.

   [1] Alexandrov, Albert, et al. "LogGP: Incorporating long messages into the LogP model for parallel computation." Journal of parallel and distributed computing 44.1 (1997): 71-79.

   Thank you.
