In our earlier work we defined such inefficiency patterns for MPI-2 one-sided communication, although still based on a serial trace-analysis scheme with limited scalability. In this article we show how wait states in one-sided communications can be detected in a more scalable fashion by taking advantage of a new scalable trace-analysis approach based on a parallel replay, which was originally developed for MPI-1 point-to-point and collective communication. Moreover, we demonstrate the scalability of our method and its usefulness for the optimization cycle with applications running on up to 32,768 cores.<\/jats:p>","DOI":"10.1177\/1094342011406758","type":"journal-article","created":{"date-parts":[[2011,6,8]],"date-time":"2011-06-08T23:08:10Z","timestamp":1307574490000},"page":"227-236","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Scalable detection of MPI-2 remote memory access inefficiency patterns"],"prefix":"10.1177","volume":"26","author":[{"given":"Marc-Andr\u00e9","family":"Hermanns","sequence":"first","affiliation":[{"name":"Laboratory for Parallel Programming, German Research School for Simulation Sciences, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Geimer","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich, J\u00fclich Supercomputing Centre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernd","family":"Mohr","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich, J\u00fclich Supercomputing Centre, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Felix","family":"Wolf","sequence":"additional","affiliation":[{"name":"Forschungszentrum J\u00fclich, J\u00fclich Supercomputing Centre, Germany"},{"name":"Laboratory for Parallel Programming, German Research School for Simulation Sciences, Germany"},{"name":"Department of Computer Science, RWTH Aachen University, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,6,8]]},"reference":[{"key":"bibr1-1094342011406758","doi-asserted-by":"publisher","DOI":"10.1109\/88.219861"},{"key":"bibr2-1094342011406758","first-page":"49","volume":"10","author":"Becker D.","year":"2009","journal-title":"Scalable Computing: Practice and Experience"},{"key":"bibr3-1094342011406758","doi-asserted-by":"crossref","first-page":"702","DOI":"10.1002\/cpe.1556","volume":"22","author":"Geimer M.","year":"2010","journal-title":"Concurrency and Computation: Practice and Experience"},{"key":"bibr4-1094342011406758","doi-asserted-by":"publisher","DOI":"10.1016\/j.parco.2009.02.003"},{"key":"bibr5-1094342011406758","first-page":"156","author":"Hermanns M.-A.","year":"2005","journal-title":"Proceedings of the 11th Euro-Par Conference, volume 3648 of Lecture Notes in Computer Science"},{"key":"bibr6-1094342011406758","unstructured":"Kn\u00fcpfer A.
