Memory Technology Impacts on Current, Near-Term, and Future Systems
TimeTuesday, June 18th9:15am - 9:37am
DescriptionFor many applications, memory continues to be the latency and bandwidth bottleneck. A wide variety of emerging memory technologies and architectures are attempting to alleviate these constraints, but they face substantial hurdles in providing enough useful bandwidth to the processor. This talk will show recent performance results from the Sandia Astra system, which is currently the largest Arm-based HPC system. Many of these results can be attributed to the increased memory bandwidth available on the system. We will also present results from a recent study by the US DOE Exascale Computing Project Memory Working Group to evaluate future improvements to High Bandwidth Memory technology. Finally, we will explore several complementary efforts to improve the performance of HPC systems by adding accelerators with a memory focus.
