The Sparc compilers were the NAG, ParaSoft, Pacific-Sierra Research, and Edinburgh Portable Compilers Fortran 90 compilers. The benchmark suite contains some codes meant to test specific language features and others which are real scientific production compilers. The emphasis of the benchmark study is performance of the code generated by the compilers, i.e., speed of the codes. The codes are available via anonymous ftp from unmfys.phys.unm.edu in the directory pub/quetzal. A report describing the benchmark results will be published in the upcoming November/December issue of the Fortran Journal (contact walt@fortran.com for subscription information). John John K.

The only one method that I know is the work of C.R.Dohrmann et al.(1), where basically, cubic spline and generalized cross-validation were adopted. I am wondering if someone out there worked on and/or is famillier with this topic who can point me to related reference or is willing to share his/her ideas with me. Besides, I would like to know the standard (the simplest) version of low-pass filter. Thanks in advance!

I need a numerical analysis text for a second semester Scientific Computation course. According to the syllabus, we are supposed to cover the following: Multivarate rootfinding and optimization Linear programming Multivariate interpolation Multivariate ODE Systems of linear equations Matrix Theory Numerical Solution of Linear systems Numerical solution of large sparse systems Eigenvalue problem Theory Computation Least square approximation Parallel numerical computation The students are undergrads in computer science, who have taken the first semester of the course (basically, the first semester consists of univariate topics, while the second consists of multivariate topics). They will have taken 3 semesters of calculus, have a knowledge of programming, and learned how to use Mathematica in the previous semester's course. If possible, I would like to find a Mathematica-based text, although I don't hold out a lot of hope. Thanks. Art Werschulz InterNet: agw@cs.columbia.edu ATTnet: Columbia U. (212) 939-7061, Fordham U.

Project GNU of the Free Software Foundation posted this survey to several special-interest Newsgroups in July of this year. We were quite pleased (if somewhat overwhelmed!) by the volume of interest, and the number of responses. We also want to apologize for the length of time it has taken to analyze the responses, and to, in turn, present this reply to you. While the material gathered was quite interesting, the most important item learned from the survey was that we need to ask the question a little better. So, with your indulgence, here are some statistics from the July Survey, followed by a second Survey we would like you to consider: From the 400 messages received in response to the GNU Math Survey #1, these mathematical packages (both free and commercial) were mentioned as being used by the indicated percentage of respondents: matlab 34% mathematica 32% gnuplot 28% maple 27% octave 17% nag 17% lapack 14% imsl 12% linpack 8% eispack 5% blas 5% spss 4% Most of the respondents replied to what free mathematical software was most desired. The kinds of software, and the number of persons indicating each are: - - graph/plot/contour/data_massaging 2D and 3D (76) - - symbolic computation (65) - - lin. algebra + num. analysis (C/C++) (52) - - matlab equiv. (34) - - stat package (26) - - Fortran 77/90 (25) - - optimization (16) - - imsl/nag (14) - - FEM (8) ... and lots of also-rans. =================================================== GNU Math Software Survey #2: This is our second try at asking about what numerical software people need. From our first try, we learned how to ask the question better :-). The GNU project wants to put together a collection of free software for widely useful numerical computations. We need to make up a task list saying which routines this collection needs to have. We'd like your help in deciding what to put in this. If you use software packages that do standard numerical calculations, what precisely are the standard calculations you use? That is, looking at just the routines you actually use, what jobs do they do? We're looking for brief but specific answers, like these made-up examples: * "Find a root of an arbitrary real-valued function of a real argument, given a black box that computes the function." * "Find the eigenvalues of a Hermitian matrix up to 100x100 in size." * "Least-squares fit of an Nth degree polynomial in up to 5 variables. We use up to 10,000 data points, each of which can have any arbitrary values of those 5 independent variables." If you use subroutines from a collection such as NAG or IMSL, please answer describing the particular routines from the collection you actually use. A general answer such as "we use IMSL" doesn't give us specific guidance. Please don't include free packages such as Octave and Gnuplot in your answer. Since there is already free software for those jobs, we don't need to them in our task list. Please don't include symbolic algebra programs in your answer. Symbolic algebra programs are very important, but they are a different category of software. Here we are asking about the more traditional numerical calculations--the first thing people imagined computers were for. (The GNU project has a symbolic algebra program, JaCaL; while still lacking many important features, it is usable for some purposes.) Please send your replies to our survey to: math-sw-survey@gnu.ai.mit.edu Thank you! ------------------------------ From: Victor Malyshkin Date: Tue, 1 Nov 1994 12:35:48 +0800 (MYT) Subject: Meeting on Parallel Computing in Russia FIRST ANNOUNCEMENT AND CALL FOR PAPERS PARALLEL COMPUTING TECHNOLOGIES (PaCT-95).
