> Vortragstitel: Self-consistent MPI Performance Guidelines
> 
> Abstract:
> 
> The MPI Standard deliberately does not make any performance guarantees, but
> users expect MPI implementations to deliver good performance that is in
> some sense portable across platforms and MPI implementations.
> In this talk we formulate and discuss performance guidelines and conditions
> that good MPI implementations can be expected to fulfill by relating aspects
> of the MPI standard to each other. We claim that such self-consistent
> performance guidelines help toward achieving performance portability.
> The formulation could be used by benchmarks and tools, such as SKaMPI and
> Perfbase, to automatically verify whether a given MPI implementation
> fulfills basic performance guidelines. We present examples where some
> of these requirements are not satisfied, demonstrating that there remains
> room for improvement in MPI implementations.
