software_title: "Synthetic Proxy Infrastructure for Task Evaluation"
acronym: "SPITE"
doi: "https://doi.org/10.11578/dc.20171025.1932"
description: "The Synthetic Proxy Infrastructure for Task Evaluation is a proxy application\
  \ designed to support application developers in gauging the performance of various\
  \ task granularities when determining how best to utilize task based programming\
  \ models.The infrastructure is designed to provide examples of common communication\
  \ patterns with a synthetic workload intended to provide performance data to evaluate\
  \ programming model and platform overheads for the purpose of determining task granularity\
  \ for task decomposition purposes. This is presented as a reference implementation\
  \ of a proxy application with run-time configurable input and output task dependencies\
  \ ranging from an embarrassingly parallel scenario to patterns with stencil-like\
  \ dependencies upon their nearest neighbors. Once all, if any, inputs are satisfied\
  \ each task will execute a synthetic workload (a simple DGEMM of in this case) of\
  \ varying size and output all, if any, outputs to the next tasks.The intent is for\
  \ this reference implementation to be implemented as a proxy app in different programming\
  \ models so as to provide the same infrastructure and to allow for application developers\
  \ to simulate their own communication needs to assist in task decomposition under\
  \ various models on a given platform."
