The multitasking was done by using the Los Alamos Multitasking Control Library, which is a superset of the CRAY multitasking library. Autotasking is done by using constructs which are only comment cards if the source code is not run through a preprocessor. The three-dimensional algorithm has pre sented a number of problems that simpler algorithms, such as those for one-dimensional hydrodynamics, did not exhibit. Problems in converting the serial code, orig inally written for a CRAY-1, to a multitasking code are discussed. Autotasking of a rewritten version of the code is discussed. Timing results for subroutines and hot spots in the serial code are presented and suggestions for additional tools and debugging aids are given. Theo retical speedup results obtained from Amdahl's law and actual speedup results obtained on a dedicated machine are presented. Suggestions for designing large parallel codes are given. <\/jats:p>","DOI":"10.1177\/109434208900300206","type":"journal-article","created":{"date-parts":[[2007,3,18]],"date-time":"2007-03-18T05:39:00Z","timestamp":1174196340000},"page":"92-99","source":"Crossref","is-referenced-by-count":4,"title":["Parallel Processing a Three-Dimensional Free-Lagrange Code: a Case History"],"prefix":"10.1177","volume":"3","author":[{"given":"David A.","family":"Mandell","sequence":"first","affiliation":[{"name":"LOS ALAMOS NATIONAL LABORATORY LOS ALAMOS, NEW MEXICO\r87545"}]},{"given":"Harold E.","family":"Trease","sequence":"additional","affiliation":[{"name":"LOS ALAMOS NATIONAL LABORATORY LOS ALAMOS, NEW MEXICO\r87545"}]}],"member":"179","published-online":{"date-parts":[[1989,6,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1145\/1465482.1465560"},{"key":"atypb2","unstructured":"Computer Documentation Group. 1981.
