INFORMATION FOR CONTRIBUTORS Scope of Articles The International Journal of Supercomputer Applications and High Performance Computing, published quarterly by the MIT Press, is directed to researchers in computational science, as well as to educators, programmers, designers and users of computers who have particular interests in the application and development of supercomputers. The goal of the journal is to provide a lively forum for the communication of original research papers and timely review articles on the use of supercomputers to solve complex modeling problems in a spectrum of disciplines. The emphasis will be on experiences with the use of supercomputers rather than on the exposition of computational results peculiar to a specific research topic. Software techniques that apply to classes of problems often cross disciplines; articles should focus on the exchange of such techniques, as well as present methods for analyzing, measuring and applying algorithms and solution schemes related to particular application areas. The scope of the journal is reflected by the specialties of the board of contributing editors. Sample topic areas include aerospace engineering, artificial intelligence and knowledge processing, astrophysics, atmospheric research and meteorological forecasting, automotive design and production, computational aerodynamics, computer graphics and imaging, cryptographic analysis, economic modeling, implementation techniques and pragmatic software and architectural considerations, integrated circuit design, molecular biology, motion-picture graphics, nuclear fusion research, performance studies, petroleum reservoir engineering and hydrology simulations, pharmaceutical research, structural analysis and computer-aided design, and theoretical and experimental physics. Submission of Manuscripts Send four copies of individual manuscripts, including a suggestion of the appropriate contributing editor for review of the article, to: Dr. Jack Dongarra Dept. of Computer Science 104 Ayres Hall University of Tennessee Knoxville, TN 37996-1301 Special Issues Proposals for issues dedicated to a particular topic of interest to the journal's audience will be considered. Once accepted, a guest editor will be appointed and the special issue will be coordinated through the editorial office of the journal. Submit four copies of special issue proposals, with a brief biography of each submitter, to: Dr. Joanne L. Martin IBM Corporation Neighborhood Road Kingston, NY 12401 Authors wishing to provide manuscript by electronic transmittal are requested to contact the editors for information about formats and procedures. Only original papers will be considered. Manuscripts are accepted for review with the understanding that the same work has not and will not be submitted for consideration elsewhere, and that its submission for publication has been approved by all of the authors, the institution where the work was performed, and the appropriate funding agencies. It is further understood that any person cited as a source of personal communications has approved such citation; written authorization may be required at the editor's discretion. Articles and any other material published in The International Journal of Supercomputer Applications and High Performance Computing represent the opinions of the authors and should not be construed to reflect the opinions of the editors or the publisher. To comply with the U.S. Copyright law, authors are required to sign a copyright transfer form before publication. It is the policy of MIT Press to own the copyright to the contributions it publishes, and to facilitate the appropriate reuse of this material by others; the transfer of copyright grants authors and their employers full rights to reuse their own material. Authors submitting a manuscript do so on the understanding that if the manuscript is accepted for publication, copyright for the article, including the right to reproduce the article in all forms and media, shall be assigned exclusively to the publisher. Authors are responsible for obtaining permissions to use photographs, drawings, tables, and other previously published material in their articles. Organization of Manuscripts Publication time can be minimized if the manuscript is carefully prepared according to the following style rules: Form of Manuscript: Submit typed manuscripts in quadruplicate, including tables and illustrations, preferably triple-spaced, but at least double-spaced, on one side of 8 1/2 X 11-in. white paper. Number each page. Page 1 should contain the article title, authors' names, and complete affiliations. Page 2 should contain a proposed running head (abbreviated form of the title) of less than 30 characters and the name, mailing address and telephone number of the author to whom the queries should be addressed. Page 2 should also contain a description of any special symbols used in the manuscript. Summary: Page 3 should contain a short summary (no more than 150 words) that describes the problem to be solved, at a level that will appeal to interested readers across disciplines. The summary should also define the significance of the work within a general scientific framework, and establish its computational requirements. Computational methods and conclusions reached should be described briefly. Introduction: A concise introduction should present the subject of the paper in the context of previous studies in the discipline, and describe models or hypotheses tested. Results and Discussion: This section may be subdivided by further headings or may be combined. Use section numbers for the first three levels of headings: 1., 1.1, 1.1.1. Tables: Tables should be numbered consecutively with Arabic numerals in order of appearance in the text, and grouped at the end of the manuscript. Each table should be typed double-spaced on a separate page. A short descriptive caption should be typed directly above each table and any necessary footnotes (indicated by superscript lowercase letters) should be typed directly below the table. Extensive tables to be reproduced as photoengravings should be typed carefully in the exact camera-ready format desired. Figures and Illustrations: Provide camera-ready figures and illustrations. Number and label concisely all illustrations on the back or bottom corners of the front, and group all at the end of the manuscript. A sharp image and good contrast are essential for quality reproductions; submit photographs for detailed halftones. Show only essential information on charts and graphs (i.e., coordinate axes, major grid lines, and lines of points of interest). A list of all legends should be typed consecutively on separate pages numbered at the end of the manuscript. Figures should be planned to fit the proportions of the printed page. Lettering on the original figure should be large enough to be legible after reduction (approximately 50% to 60%). Differences in type size within a single figure should be no more than approximately 15%. Characters should be approximately 3/16-in. high. (Leroy lettering size 140). Symbols used to identify points within a graph should be large enough that they will be easily distinguishable after reduction. Graphs should be plotted with generous margins in black ink on stiff white paper no larger than 8 1/2 X 11 in. Grid lines that are to show must be inked in black. Halftones should be submitted not larger than 6 1/2 X 4 1/2 in. For color illustrations, submit transparencies (35 mm) or glossy photographs. Do not submit photographs with silk or canvas finishes, or mounted on art boards. Make photographs the same size or larger than to be used in the journal, but no larger than 8 1/2 X 11 in. If several illustrations are to be used, submit artwork all of the same size to be reduced at the same percentage. To indicate cropping, put slash marks using a black marking pen outside the area where the image is to be cropped. For transparencies, these marks can be made on the cardboard holder or on masks placed over the slide. Cost for printing color art is $1,200 per page. Mathematics: Type mathematics exactly as it should appear. Numbers for displayed equations should be placed in parentheses at the right margin. Indicate best breaks for equations in case they will not fit on one line. In typewritten manuscripts, it will be assumed that all letters in displayed equations are to appear in italics unless marked as boldface or roman. Mark symbols in text as italics or boldface. If not marked, it will be assumed that letter symbols in text are to be set in roman type. References: Only articles that have been published or are in press may be included in the references. Unpublished results (including articles submitted for publication) or personal communications should be cited as such within the text. Alphabetize the reference list by first author's last name. Cite references in text by author and date, for example: (Doe et al., 1982). Include the following information in the references: 1.

Special Sections Correspondences: This section is open to succinct reports of important research findings. They should not exceed six double-spaced typewritten pages including tables and illustrations. Do not use any section headings except for Acknowledgements and References. All correspondence articles must have summaries. Illustrative materials should be kept to a minimum (usually not more than two or three table and figures). Literature should be cited as for full-length papers. This section does not guarantee an accelerated means of publication, but is designed to offer the opportunity to present in brief form noteworthy results of works in progress and descriptions of evolving techniques and methods. Industrial Applications: Designed to highlight the needs and interests of computational scientists in industrial settings, this section is open to full papers or brief reports covering work performed in an applied research environment. Perspectives: At the discretion of the editors, this section will enable the publication of papers describing concepts, philosophical issues, or summary reports concerning advances being made in the field of scientific computation. Contributions should not exceed six double-spaced typewritten pages including tables and illustrations. Do not use any section headings except for Acknowledgment and References. Do not include a summary. Literature should be cited as for full-length papers. Proofs and Time of Publication Decisions on papers will be made as rapidly as possible. After an initial examination by the editors to confirm suitability of the article for the interdisciplinary readership of Supercomputer Applications, the editors will strive to have manuscripts reviewed promptly by an editorial board member and at least one other peer reviewer. When papers are accepted subject to revision, only a single revised version will be considered. Proofs will be reviewed by the editors in consultation with the author within six months of acceptance of an article. It is necessary to regard accepted manuscripts as final texts to which no changes should be made. Any substantive changes made in the manuscripts to conform with the conventions of Supercomputer Applications will be submitted to authors for approval before the proof stage.
