Stephen Pawlowski of Intel gave an interesting keynote today at ISC 2013. He continued the theme of yesterday’s keynote to address challenges our market faces in getting to exascale computing. Here is a summary of the points he made during his talk: Getting to exascale by 2020 requires performance improvement of 2x every year Innovations anticipated include stacked chips and optical layers DRAM is not scaling with Moore’s Law More power goes into transferring data than in computing Need to operate transistors near threshold New materials for DRAM needed. Resistive memory could replace DRAM. Need to explore both the big die and the small die paths as we approach 2020 Big die path leads to 10 billion transistors on a …
