Subject: [OMPI users] Automated tuning tool
From: Terry Frankcombe (terry_at_[hidden])

There's been quite some discussion here lately about the effect of OMPI
tuning parameters, particularly w.r.t. collectives.

Is there some tool to probe performance on any given network/collection
of nodes to aid optimisation of these parameters?

(I'm thinking something along the philosophy of ATLAS.)
