Waiting for Moore’s Law to save your serial code start getting bleak in 200405:33

Moore’s Law is not at all dead…06:58

At end of day, we keep using all those new transistors.08:02

That Power and Clock Inflection Point in 2004… didn’t get better.08:18

Not a new problem, just a new scale…09:54

How to get same number of transistors to give us more performance without cranking up power?10:30

And how to get more performance from more transistors with the same power.10:59

Prototypical Application: Serial Weather Model12:07

First parallel Weather Modeling algorithm: Richardson in 191712:38

Weather Model: Shared Memory (OpenMP)13:37

Weather Model: Accelerator (OpenACC)14:27

Directives: an elegant and common approach.16:46

Weather Model: Distributed Memory (MPI)18:00

The pieces fit like this…19:38
