CURRENT ISSUES IN COMPUTATIONAL METHODS- ROUNDTABLE PROXY APPS, MINI APPS, RESEARCH APPS: PROGRESS AND LESSONS LEARNED

摘要

A current trend in the research and development of numerical algorithms for advanced exascale computing architectures involves the production of proxy-apps. mini-apps, and research apps. A major goal of these efforts is to provide open-source and distributable software applications that can be used by researchers and computer vendors to investigate algorithms suitable for advanced exascale architectures. This panel session will address questions such as: What are these various applications, and how are they being used? What are the costs of development of these apps? What is the optimal balance between size of proxy apps and flexibility for research investigations? What approaches can be used to assess whether these apps are representative of the actual applications? What are some success stories for which these apps have been beneficial? What are some lessons learned for the development of these apps in the future?
