SUMMARY:Beatnik: A Novel Global Communication Mini-Application
DESCRIPTION:Jason Stewart and Patrick Bridges (University of New Mexico)\n
 \nBeatnik is a novel open source mini-application that exercises the compl
 ex communication patterns often found in production codes but rarely found
  in benchmarks or mini-applications. It simulates 3D Raleigh-Taylor instab
 ilities based on Pandya and Shkoller’s Z-Model formulation using the Caban
 a performance portability framework. This paper presents both the high-lev
 el design and important implementation details about Beatnik, along with f
 our benchmark setups for evaluating different aspects of HPC communication
  system performance. Evaluation results demonstrate Beatnik's scalability 
 on modern accelerator-based systems using weak and strong scaling tests up
  to 1024 GPUs, along with Beatnik's ability to expose communication challe
 nges in modern systems and solver libraries.\n\nTag: Message Passing, Netw
