N2 - The Xevolver framework has been developed to enable application programmers to define their own code translation rules outside of their codes so that they can express platform-specific optimizations separately from algorithm-level application codes. Due to the diversity of HPC node architectures, the Xevolver framework has so far mainly been used to separate node-level code optimizations from application codes. However, user-defined code transformation rules are also potentially useful for optimizing MPI applications without messing up their codes. Therefore, this paper shows a case study of using the Xevolver framework to optimize MPI applications through customizable code transformations without loss of high performance portability, and discusses the benefits of the framework.
