Subject: [OMPI users] Expected scaling of collective operations with number of processors.
From: Adam Higuera (ahig321_at_[hidden])

Hello:

I'm trying to produce a performance model for a piece of software, and I'd
like to know the expected performance behavior of MPI_Scatter and
MPI_Gather as the number of processors increases. I've searched to no
avail for a publication on this topic.

Can you point me in the direction of something like that?

Thanks,
-Adam Higuera
