Concurrency Kit provides a plethora of concurrency primitives and lock-less and lock-free data structures designed to aid in the design and implementation of high performance scalable concurrent systems. It was designed to minimize dependencies on operating system-specific interfaces, and most of the interface relies only on a strict subset of the standard library and more popular compiler extensions.
PerlDaemon is a minimal Unix daemon framework. It can be programmed in Perl to perform any task. It supports automatic daemonizing, logging and logrotate support, clean shutdown, and PID files (including a check on startup). It's easy to configure and easy to extend by customizing the daemonloop subroutine.
Algebraic Modelling System (AMS) is an approach to algebraic model representation that enables the expression and storage of models and their related instance data in a portable XML format. It is also able to convert these models to target modelling languages by use of simple XSL translation stylesheets. By using a representation format that is independent of any particular modelling system, your models become portable to any modelling system. An XML-based format also lends itself more easily to distributed computing, Web services, and other enterprise-level computing solutions.
