“…Packages that specifically explore (block-diagram) program composition in a variety of domains also inspire our work, such as nesC [33] and Knit [34] for composing low-level operating systems components, as well as Gaia's LuaOrb [35] scripting language for controlling components within active spaces. Other projects, such as Ninja Paths [36], focus on automatically stringing together a linear set of widearea, distributed software components to perform a necessary service.…”

Abstract-We present a middleware platform for assembling pervasive applications that demand fault-tolerance and adaptivity in distributed, dynamic environments. Unlike typical adaptive middleware approaches, in which sophisticated component model semantics are embedded into an existing, underlying platform (e.g., CORBA, COM, EJB), we propose a platform that imposes minimal constraints for greater flexibility. Such a tradeoff is advantageous when the platform is targeted by automatic code generators that inherently enforce correctness by construction.Applications are written as simple, single-threaded programs that assemble and monitor a set of distributed components. The approach decomposes applications into two distinct layers: (1) a distributed network of interconnected modules performing computations, and (2) constructor logic that assembles that network via a simple block-diagram construction API. The constructor logic subsequently monitors the configured system via a stream of high-level events, such as notifications of resource availability or failures, and consequently provides a convenient, centralized location for reconfiguration and debugging. The component network is optimized for performance, while the construction API is optimized for ease of assembly.

“…We can say we implemented a Lua CoG Kit, that also offers support for rapid prototyping of Grid applications. In this line, the LuaOrb system [13] offers mappings between the Lua language and CORBA, COM and Java components, providing interoperability among these components. We believe that integrating both ALua with LuaOrb will allow the application developer to explore Grid services (such as resource management, security, and resource finding) while high-level components are developed using the tools that are most appropriate.…”

SUMMARYThe heterogeneous and dynamic nature of Grid environments place new demands on models and paradigms for parallel programming. In this work we discuss how ALua, a programming system based on a dual programming language model, can help the programmer to develop applications for this environment, monitoring the state of resources and controlling the application so that it adapts to changes in this state.

“…These objects run on a customized ORB, which supports communication and context-awareness between the objects. The Gaia [19] project also uses a high level scripting language called LuaOrb [5]. Based on the interpreted language Lua [10], it provides language binding between Lua and CORBA, COM and Java.…”
