“It seems that, in order to understand the Application Challenges of the next 7-10 years, we need to have a handle on what the new technologies might be that developers will have to work with. Yet it seems like almost every aspect – every echnical details – related to the technologies of the future, particularly with exascale are up in the air right now. Have you determined some approaches that application developers could actually be using today to insure they have code that will be scalable on exaflops machines?”
