Performance Portability for Unstructured Mesh Physics

PDF Version Also Available for Download.

Description

ASC legacy software must be ported to emerging hardware architectures. This paper notes that many programming models used by DOE applications are similar, and suggests that constructing a common terminology across these models could reveal a performance portable programming model. The paper then highlights how the LULESH mini-app is used to explore new programming models with outside solution providers. Finally, we suggest better tools to identify parallelism in software, and give suggestions for enhancing the co-design process with vendors.
