However, many applications obtain poor I\/O performance on modem parallel machines. This two-part special issue of the Intemational Journal of High Performance Computing Applications contains papers that describe the I\/O requirements and the techniques used to perform I\/O in real parallel applications. The authors first explain how the I\/O application program inter face (API) plays a critical role in enabling such applications to achieve high I\/O performance. They describe how the commonly used UNIX I\/O interface is inappropriate for parallel I\/O and how an explicitly parallel API with support for collective I\/O can help the underlying I\/O hardware and software perform I\/O efficiently. They then describe MPI- IO, a recently defined, standard, portable API specifically designed for high performance parallel I\/O. They conclude with an overview of the papers in Part 1 and Part 2 of this special issue.<\/jats:p>","DOI":"10.1177\/109434209801200401","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T20:17:47Z","timestamp":1173039467000},"page":"389-395","source":"Crossref","is-referenced-by-count":19,"title":["I\/O in Parallel Applications: the Weakest Link"],"prefix":"10.1177","volume":"12","author":[{"given":"Rajeev","family":"Thakur","sequence":"first","affiliation":[{"name":"MATHEMATICS AND COMPUTER SCIENCE DIVISION, ARGONNE NATIONAL\rLABORATORY, ARGONNE, ILLINOIS, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ewing","family":"Lusk","sequence":"additional","affiliation":[{"name":"MATHEMATICS AND COMPUTER SCIENCE DIVISION, ARGONNE NATIONAL\rLABORATORY, ARGONNE, ILLINOIS, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William","family":"Gropp","sequence":"additional","affiliation":[{"name":"MATHEMATICS AND COMPUTER SCIENCE DIVISION, ARGONNE NATIONAL\rLABORATORY, ARGONNE, ILLINOIS, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1998,12,1]]},"reference":[{"key":"atypb1","volume-title":"Preliminary survey of I\/O intensive applications","author":"Applications Working Group of the Scalable I\/O Initiative.","year":"1994"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4613-1401-1_7"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.21236\/ADA324930"},{"key":"atypb4","volume-title":"Proceedings of Supercomputing '95","author":"Crandall, P."},{"key":"atypb5","volume-title":"In Proceedings of the Workshop on I\/O in Parallel Computer Systems at IPPS '93","author":"del Rosario, J."},{"key":"atypb6","doi-asserted-by":"publisher","DOI":"10.1109\/2.268887"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1109\/M-PDT.1995.414842"},{"key":"atypb8","volume-title":"Proceedings of the Sixth Symposium on the Frontiers of Massively Parallel Computation","author":"Fineberg, S."},{"key":"atypb9","volume-title":"Proceedings of Supercomputing '93","author":"Galbreath, N."},{"key":"atypb10","volume-title":"In Proceedings of 40th IEEE Computer Society International Conference (COMPCON 95)","author":"Gibson, G."},{"key":"atypb11","volume-title":"Proceedings of the 9th ACM International Conference on Supercomputing","author":"Huber, J."},{"key":"atypb12","volume-title":"Std. 1003.1.
