Scripting is a programming technique in which applications are constructed by composing specially designed, pre-packaged software components using a restricted set of scripting operators. Scripting simplifies programming by cutting down the number of the syntactic and semantic features found in a complete programming language, yet is inherently open-ended in that software components can be prov...

The resource managers (e.g., batch queue schedulers) used at many parallel and distributed computing centers can be complicated systems for the average user. A large number of command-line options, environment variables, and site-specific configuration parameters can be overwhelming. Therefore, we have developed a simple Web-based interface, called PBSWeb, to the Portable Batch System (PBS), wh...

I n computing, we often solve a complex problem by adding another level of indirection. For example, in Unix file systems, an index node, or inode, data structure lets the operating system allocate files concurrently and sparsely while still providing an efficient random-access capability. When we want to customize large, complex systems or express fluid, rapidly changing requirements, we frequ...

Scripting in radiotherapy treatment planning systems not only simplifies routine planning tasks but can also be used for clinical research. Treatment planning scripting can only be utilized in a system that has a built-in scripting interface. Among the commercially available treatment planning systems, Pinnacle (Philips) and Raystation (Raysearch Lab.) have inherent scripting functionality. CMS...

A transpiler converts code from one programming language to another. Many practical uses of transpilers require the user be able guide or customize program produced a given input program. This customizability is important for satisfying many application-specific goals such as ensuring performance, readability, ease exposition maintainability, compatibility with external environment analysis too...
