Abstract:
In this session we will talk about how to improve strong scaling for molecular dynamics applications. Using the NAMD molecular dynamics code as our primary case study, we will discuss the types of issues that can impede scaling, how to use already available and custom tools to discover such issues, and how to build a model to help analyze and predict scaling performance. Although this session is primarily focused on molecular dynamics applications, most of the lessons can be applied equally well to many other areas and applications.
