High-bandwidth memory can improve a computer's performance. On-package memory (OPM) is a popular option in many commercial systems. Before this effort, little was known about OPM's implications on speed and power use. The team experimentally characterized and analyzed modern OPM storage. They provided guidelines on tuning the memory to speed up high-performance computing (HPC) applications.
This study about OPMs is both essential and fundamental for advancing computing systems. For example, it motivates software-architecture co-design exploration. Further, it validates models and simulations. It also has resulted in general optimization guidelines. The work shows how to tune applications and architectures for the best performance on platforms with certain OPMs.
