Future of Memory Technology for Exascale and Beyond

SESSION: Future of Memory Technology for Exascale and Beyond


TIME: 1:30PM - 3:00PM

SESSION CHAIR: Subhash Saini

Panelists:Richard Murphy, Shekhar Borkar, Bill Dally, Andreas Hansson, Doug Joseph, Peter Kogge, Troy Manning


Memory technology is in the midst of profound change as we move into the exascale era. Early analysis, including the DARPA UHPC Exascale Report correctly identified the fundamental technology problem as one of enabling low-energy data movement throughout the system. However, the end of Dennard Scaling and the corresponding impact on Moores Law has begun a fundamental transition in the relationship between the processor and memory system. The lag in the increase in the number of cores compared to what Moores Law would provide has proven a harbinger of the trend towards memory systems performance dominating compute capability. This panel will focus on three critical questions: (1) What is the right memory technology for exascale and beyond? (2) Given that memory capacity per core has declined on supercomputers since 2003, what can be done to continue to facilitate scaling? (3) What about tighter processor/memory operations and other potentially disruptive architectures?
