Genders is a static cluster configuration database used for cluster configuration management. It is used by a variety of tools and scripts for management of large clusters. The Genders database is accessed by every node in a cluster, either through a networked file system or by replicating the database on every node of the cluster. The database describes the layout and configuration of the cluster so that tools and scripts can sense the variations of cluster nodes. By abstracting this information into a plain text file, it becomes possible to change the configuration of a cluster by modifying only one file.

Byteman is a tool which makes it easy to trace, monitor and test the behaviour of Java application and JDK runtime code. It injects Java code into your application methods or into Java runtime methods without the need for you to recompile, repackage or even redeploy your application. Injection can be performed at JVM startup or after startup while the application is still running. Injected code can access any of your data and call any application methods, including where they are private. You can inject code almost anywhere you want and there is no need to prepare the original source code in advance. You can even remove injected code and reinstall different changes while the application continues to execute.

TCLAP is a small, flexible library that provides a simple interface for defining and accessing command line arguments. It was intially inspired by the user friendly CLAP libary. The difference is that this library is templatized, so the argument class is type independent. Type independence avoids identical-except-for-type objects, such as IntArg, FloatArg, and StringArg. While the library is not strictly compliant with the GNU or POSIX standards, it is close.

The C and C++ languages and many operating system environments do not provide full support for Unicode and standards-compliant text handling services. Even though some platforms do provide good Unicode text handling services, portable application code can not make use of them. The ICU4C libraries fills in this gap. ICU4C provides an open, flexible, portable foundation for applications to use for their software globalization requirements. ICU4C closely tracks industry standards, including Unicode and CLDR (Common Locale Data Repository).

Simply put, it assumes that you have two text files containing numerical values, and the two files are expected to be identical, or at least numerically similar. ndiff allows you to specify absolute and/or relative error tolerances for differences between numerical values in the two files, and then reports only the lines with values exceeding those tolerances. It also tells you by how much they differ.
