SUMMARY:Exploring and Quantifying How Communication Behaviors in Proxies R
 elate to Real Applications
DESCRIPTION:Omar Aaziz and Jeanine Cook (Sandia National Laboratories), Jo
 nathan Cook (New Mexico State University), and Courtenay Vaughan (Sandia N
 ational Laboratories)\n\nProxy applications, or proxies, are simple applic
 ations meant to exercise systems in a way that mimics real applications (t
 heir parents). However, characterizing the relationship between the behavi
 or of parent and proxy applications is not an easy task. In prior work, we
  presented a data-driven methodology to characterize the relationship betw
 een parent and proxy applications based on collecting runtime data from bo
 th and then using data analytics to find their correspondence or divergenc
 e. We showed that it worked well for hardware counter data, but our initia
 l attempt using MPI function data was less satisfactory. In this paper, we
  present an exploratory effort at making an improved quantification of the
  correspondence of communication behavior for proxies and their respective
  parent applications. We present experimental evidence of positive results
  using four proxy applications from the current ECP Proxy Application Suit
 e and their corresponding parent applications (in the ECP application port
 folio). Results show that each proxy analyzed is representative of its par
 ent with respect to communication data. In conjunction with our method pre
 sented earlier (correspondence between computation and memory behavior), w
 e get a strong understanding of how well a proxy predicts the comprehensiv
 e performance of its parent.\n\nTag: Benchmarks, Parallel Programming Lang
