The focus and contribution of this work is to study the I\/O behavior of the Hartree-Fock (HF) method using PAS SION. HF's I\/O phases can contribute up to 62.34% of the total execution time. The authors reduce the execution time and I\/O time up to 54% and 6%, respectively, of that of the original case through PASSION and its optimiza tions. Additionally, the authors categorize the factors that affect the I\/O performance of HF into key application- related parameters and key system-related parameters. Based on extensive empirical results and within the ex perimental space presented in this paper, the authors orderthe parameters according to the their impact on HF's I\/O performance as follows: efficient interface, prefetching, buffering, number of I\/O nodes, striping factor, and striping unit. The authors conclude that application-related factors have a more significant effect on HF's I\/O performance than the system-related factors within the experimental space presented in this paper.<\/jats:p>","DOI":"10.1177\/109434209801200403","type":"journal-article","created":{"date-parts":[[2007,3,4]],"date-time":"2007-03-04T20:17:47Z","timestamp":1173039467000},"page":"411-439","source":"Crossref","is-referenced-by-count":0,"title":["An Experimental Study to Analyze and Optimize Hartree-Fock Application's I\/O with Passion"],"prefix":"10.1177","volume":"12","author":[{"given":"Meenakshi A.","family":"Kandaswamy","sequence":"first","affiliation":[{"name":"ELECTRICAL ENGINEERING AND COMPUTER SCIENCE, SYRACUSE\rUNIVERSITY, SYRACUSE, NEW YORK, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahmut T.","family":"Kandemir","sequence":"additional","affiliation":[{"name":"ELECTRICAL ENGINEERING AND COMPUTER SCIENCE, SYRACUSE\rUNIVERSITY, SYRACUSE, NEW YORK, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alok N.","family":"Choudhary","sequence":"additional","affiliation":[{"name":"DEPARTMENT OF ELECTRICAL AND COMPUTER ENGINEERING, NORTHWESTERN\rUNIVERSITY, EVANSTON, ILLINOIS, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David E.","family":"Bernholdt","sequence":"additional","affiliation":[{"name":"NORTHEAST PARALLEL ARCHITECTURES CENTER, SYRACUSE UNIVERSITY,\rSYRACUSE, NEW YORK, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1998,12,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1002\/jcc.540030314"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1109\/IPPS.1996.508111"},{"key":"atypb3","volume-title":"Techniques for compiling I\/O intensive parallel programs.
