Software Releases

I have not blogged much this fall because I have been busy managing a variety of software releases.  I plan to include further details in upcoming blogs, but I thought I would summarize these releases here:
  • acro 2.0 - Acro is A Common Repository for Optimizers that integrates a rich variety of optimization libraries and solvers that have been developed for large-scale engineering and scientific applications. Acro was developed to facilitate the design, development, integration and support of optimization software libraries. Thus, Acro includes both individual optimization solvers as well as optimization frameworks that provide abstract interfaces for flexible interoperability of solver components. Furthermore, many solvers included in Acro can exploit parallel computing resources to solve optimization problems more quickly.

  • utilib 4.0 - Utilib is a library of general-purpose C++ utilities, similar in spirit to the Boost libraries. While generally treated as an Acro package, Utilib is hosted in a separate subversion repository to facilitate use by projects outside of Acro.

  • PyUtilib 1.0 - PyUtilib is yet another a Python utility library. PyUtilib supports several Python projects under development at Sandia National Laboratories, including Acro, Coopr and FAST.

  • FAST 2.0 - FAST provides a collection of Python tools that support software testing. In it's current form, this does not really constitute a framework, but the plan is to develop a set of tools that support comprehensive testing of software tools.

  • Coopr 1.0 - The Coopr Python package integrates a variety of Python optimization-related packages. Most of these packages rely on externally built optimization solvers. In particular, the Acro software builds many optimizers used by Coopr packages.

The Trac wikis for these packages contain a variety of tools that I'll describe in more detail later...

Python Plugin Frameworks

Updated to include pointers to the PyUtilib Component Architecture and PnP. Various Python projects I am working on could benefit from the use of a Plug-in framework.  However, there does not appear to be a standard Python plug-in framework, though there are some mature packages that support plug-ins. Here's a summary of my recent web research: yapsy - This is a simple plug-in framework that was designed specifically to support plug-ins with no external dependencies. Mary Alchin describes a simple plugin framework , with a similar goal.  His classes provide an API for the plugins, with few supporting features (e.g. searching for plugins). André Roberge has a series of posts that describe the application of plugins to refactor a simple calculator application.  The goal of this is to illustrate the requirements for plugin frameworks, with the goal of identifying best practices for plugins. There are some interesting replies to this post, which consider implementations of the

Using AsciiDoc for Mathematical Publications

Technical writing is an integral part of my research in computer science and operations research. I have a long history using LaTeX, which is very well suited for writing technical articles that contain mathematical equations as well as code snippets. Although LaTeX can readily generate postscript and PDF output files, I have been unimpressed with tools that generate HTML from LaTeX source. Thus, I was intrigued by AsciiDoc , which promises to generate PDF, HTML and eBook formats. AsciiDoc is used to provide online documentation for software projects, and authors can publish book through O'Rielly using this tool. Thus, this is a well-developed document generation tool. I have successfully prototyped a draft book, Getting Started with Coopr , and you can browse the subversion repository for this document here . Note that the Makefile file specifies build targets for PDF, HTML and eBook files. The advantage of AsciiDoc is that you can use a simple markup language to generate

A Different Model for Writing Blog Posts

This is a blog that I have been meaning to write for some time.   I occasionally take a look at the download statistics for this blog, and recently I was prompted to do this by other bloggers who were reporting their end-of-year statistics (e.g. see Laura McLay’s review of the Punk Rock OR blog ). Unlike Laura, I do not have impressive download statistics to report about the many blogs I have written in 2011; frankly, I did not create many posts. However, an interesting pattern has emerged regarding this blog’s readership:   there are a few key blog posts that are frequently downloaded.   For example, my most frequently downloaded blog post is a survey of Python plugin software, which I wrote in 2009.   I suspect that other bloggers have seen the same thing; they have a few posts that are very popular because people do web searches on that topic.   However, it is worth stepping back and thinking about the implications of this when writing a blog. When I first started b
