Subject: referee-report for paper C502 From: "Ulrike Yang" Date: Mon, 04 Jun 2001 09:07:12 -0700 To: fox@csit.fsu.edu To Geoffrey C. Fox Please find enclosed my referee report for paper C502. Sincerely, Ulrike Meier Yang --------------------------------------------------------------------------------------------------------------------------- Paper No: C502 Date: 6/4/01 Paper Title: Parallel Iterative Solvers for Unstructured Grids Using (an) Directive/MPI Hybrid Programming Model for (the) GeoFEM Platform on SMP Cluster Architectures Authors: Kengo Nakajima and Hiroshi Okuda Referee: Ulrike Meier Yang Address: Center for Applied Scientific Computing Lawrence Livermore National Laboratory Box 808, L-560 Livermore, CA 94551 Referee Recommendations: accepted provided changes suggested are made D: Referee Comments (For Editor Only) The paper is interesting, but the authors obviously do not know the English language well. The paper cannot be published as is, however, after the paper and the abstract has been rewritten in correct English, I would recommend it for publication. E: Referee Comments (For Author and Editor) The authors describe their efforts in achieving an efficient implementation for iterative solvers on SMP cluster architectures and present their results. This includes the use of various known reordering techniques as well as the use of additive Schwarz methods to increase the robustness of localized ILU(0)- or ICCG(0)-preconditioning. Technically, this paper is very interesting. The figures are well done and aid the description of the various techniques. My main concern about this paper is its use of the English language. The paper could be greatly improved if someone who reads and writes English well could go over this paper and the abstract with the authors and correct it. There are too many mistakes (with regard to grammar, spelling, style, etc.) to write them all down in this report. It would take rewriting the paper. One reoccurring pattern is the omission of articles, 'a' or 'the', (see also above title of paper, which I corrected by adding articles). Also, it is important to check the spelling of the names of the methods, such as Schwarz (not Schwartz), Cuthill-McKee (not Cuthil Mckee) , etc.
