Optimise for scaling or efficiency preapring for exascale difficultchoice says Adrian Jackson
26 May 2017 Edinburgh - In his latest blog post "Balancing act: optimise for scaling or efficiency?" on the EPCC site, Adrian Jackson writes about choices to make when optimising parallel applications especially when preparing for exascale. There are many unknowns so it is hard to make correct choices at this moment.
He ends with: "(This) blog post is really a plea for some joined up thinking between countries and organisations doing Exascale research, so we get both revolutionary and incremental machines, we get resources that can enable both types of outcomes. After all, it looks like there will be at least four different Exascale machines/programmes, so there is room for plurality."
