This month’s column introduces the Global Arrays Toolkit (GA, http://www.emsl.pnl.gov/docs/global/), a suite of application programming interfaces (API’s) for handling distributed data structures.
With dozens of software projects involving hundreds of developers, keeping data flowing smoothly is an involved process for the Apache Software Foundation (ASF). With tens of machines distributed worldwide, gigabytes of daily downloads, and fifty hits per second on the Apache home page, system maintenance requires the varied skills of a small legion of volunteers. In the fourth in an ongoing, exclusive series, ASF co-founder Ken Coar pulls back the curtain to reveal how it all works.
Two prior Linux Magazine articles, “How To Git It” and “Embrace the Git Index”, cover basic concepts about git and explain some of the details about the git index. This article introduces many new git concepts and techniques that can be used for collaborative development, including the use and manipulation of topic and tracking branches, cloning a remote repository, details on installing a server for git repositories using HTTP and git- native protocols, and publishing a public repository via the Web.
ImageMagick is a package of tools for creating and editing images that’s not easy to get started with, but is well worth the effort. Here’s an introduction, just in time for processing those summer photos.
This is the third column introducing the basics of Unified Parallel C (UPC). UPC, Co-Array Fortran, and other new productivity-oriented programming languages are designed to simplify parallel programming and code maintenance.
The" new" Web is all shiny and collaborative, but" old school" Usenet is still chugging along. Here, Randal Schwartz connects some of the new with some of the old, scraping CPAN for news of novel Perl modules.

Designed for high-performance computing on large-scale parallel machines, including Beowulf-style clusters, Unified Parallel C provides a uniform programming model for both shared and distributed memory hardware.
Template Toolkit is great for dynamic sites, but it can also make the task of keeping a static site up-to-date. Perl Guru Randal Schwartz sings TT's virtues while building a site for budding karaoke stars.
Most developers use the Template Toolkit (TT) to generate dynamic web pages based on input parameters, but TT can help static web sites as well. Let’s take a look at a typical small, static website and how TT can help things.
In the bash shell, you can use C-style for loops in your scripts. For example, the command-line for((c=1; c<100; c++)); do gzip arch_$c.lst; done compresses 99 files, arch_1.lst ... arch_99.lst. (Thanks to Chuck Amsler.)
The best place to look for open source code depends on what you’re looking for. But rest assured, the source is out there. The trick is finding it. Here’s a guide to what’s online.
Some forethought, a clear statement of intent and practice, and a modicum of documentation can make contributors and benefactors more comfortable with donating and using open source code.
GCC 4.0 has a new optimization infrastructure, and future versions of GCC will realize even more performance improvements. Here’s an overview of what’s new and what’s to come.
Intel Corporation today began shipping five new software development tools that make it easier to create the distributed applications used in high-performance computing (HPC) clusters.
The Template Toolkit does not support any profiling tools “out of the box.” However, that didn’t stop Randal from getting the numbers — and the performance boost — he needed.
Tired of CVS? Try darcs. Creating a repository with darcs is as easy as cd ~/myproject; darcs init; darcs add -r *. Use apt-get install darcs to install or see the darcs wiki for source, tools, and more info.
