Extractions: Camelot News Download GALAHAD Documentation Contribute ... Authors of GALAHAD elcome! ALAHAD is a thread-safe library of Fortran 90 packages for solving nonlinear optimization problems. At present, the areas covered by the library are unconstrained and bound-constrained optimization, quadratic programming, nonlinear programming, systems of nonlinear equations and inequalities, and nonlinear least squares problems. GALAHAD contains the following major packages: solves quadratic programs using a primal-dual interior-point method globalized by means of a trust region. The method works in two phases, the first finding a feasible point for the set of constraints, while the second maintaining feasibility while iterating towards optimality. Once again, core linear algebraic requirements are handled by an adaptive preconditioned CG/Lanczos iteration.
Stanford Business Software Sells fortran 77 optimization codes MINOS (linear programming and nonlinear optimization), SNOPT (largescale quadratic and nonlinear programming), NPSOL (nonlinear programming), LSSOL (Linearly constrained linear least squares problems and convex quadratic programmmin), and QPOPT (linear and quadratic programming). http://www.sbsi-sol-optimize.com/

It is designed for a reader's second exposure to computer programming, whether it be through self-study or a course in computer science. The book is not just algorithms. Additional F/Fortran topics are included: separate theme chapter are devoted to complex arithmetic, file processing, list processing (the extensive chapter includes binary search trees), text processing including string searching, and recursion. Chapters can be studied in any order, as they are mostly independent; They can be selected at will according the reader's interests. The book is backed up by comprehensive appendices on the built-in procedures and summaries of the F and Fortran statements. It is recommended, although not essential, that the reader be familiar with the F or Fortrran 90/95 programming language, prior to using this text.

Extractions: Structured Programmer's Soliloquy SP or not SP that is the question: Whether 'tis nobler in the mind to suffer The rules and exceptions of outrageous FORTRAN Or to take arms against a sea of transfers And by structuring end them. To code to test No more; and by a test to say we end The heartache, and the thousand natural mistakes That FORTRAN is heir to. 'Tis a consummation Devoutly to be wish'd. To code to test. To test perchance to bomb: aye, there's the rub! For in that test of code what bugs may come When we have shuffled of this FORTRAN code, Must give us pause. There's the respect that makes calamity of so long lists. [] For who would bear the whips and scorns of time-sharing Th' operating systems wrong, the computer's crash, The pangs of despis'd code, the turnaround's delay, The insolence of compilers, and the spurns That patient coding of FORTRAN takes When he himself might his quietus make with PL/I? Who would this FORTRAN Bear, To grunt and sweat under a weary language, But that the dread of something after FORTRAN The undiscover'd country, from whose bourne No programmer returns puzzles the will, And makes us rather bear those ills we have Than fly to others that we know not of? Thus conscience does make cowards of us all, And thus the native hue of resolution Is sicklied o'er with the pale cast of thought, And enterprises of great pith and moment With this regard their currents turn away And lose the name of action. - Henry Kleine and Philip H.

Extractions: A program is a sequence of instructions that enables the computer to solve a problem. Writing a program to solve the problem can be a formidable task if the problem is complex. The overall programming process can often be simplified by using a top-down approach. The process is called a top-down design because the programmer starts with the original problem and breaks it down into smaller tasks which can be addressed separately. First, the large tasks are identified and then each of these tasks is refined filling in more details. This process allows the programmer to initially concentrate on the overall steps without getting bogged down in the details of the program, thus making the programming task more manageable. Another advantage of breaking a program down into tasks is that each task can be checked for correctness apart from the other tasks. An algorithm or plan, in the form of a flowchart or pseudocode (English-like statements), can be used to describe the problem solving process. Problem Statement Find the surface area and volume of a sphere with a given radius.
Task Parallelism And Fortran fortran M. fortran~M is a small set of extensions to fortran that supports a modular approach to the construction of sequential and parallel programs. http://www-fp.mcs.anl.gov/fortran-m/FM.html
Extractions: The task parallelism group at Argonne National Laboratory investigates applications, language constructs, compilation, and runtime system issues associated with the use of task parallelism, and mixed task/data parallelism. Much of this work is performed in the context of Fortran, but many of the techniques apply equally to other languages. High Performance Fortran (HPF) provides a convenient syntax for specifying data-parallel execution, but does not at present allow programmers to write task-parallel programs in which different tasks perform different activities at the same time. As a solution to this problem, we advocate the development of an HPF binding for the Message Passing Interface (``HPF/MPI''). This provides a standard set of functions for coupling multiple HPF tasks to form task-parallel computations. Working with Rakesh Krishnaiyer and Alok Choudhary at Syracuse University, we have developed a prototype implementation of an HPF/MPI library. This is a nontrivial exercise because (for example) sending and receiving tasks may employ different data distributions, and execute on different numbers of processors. Our prototype uses the HPF compiler produced by the Portland Group, Inc., and was demonstrated at the Supercomputing 95 conference. In future work, we plan to use the HPF/MPI prototype to investigate algorithms for high-performance communication in mixed task/data-parallel computations. We also plan to investigate other libraries that implement other communication mechanisms, such as Fortran M channels, and to compare library-based and language-based approaches to task-parallel computation.
