Dynamic deployment of a component framework with the Ubiqis system

Component frameworks provide one strategy for the development and deployment of complex multiphysics applications, which are increasingly developed by collaborative, distributed, and diverse teams, and are deployed across multiple supercomputer architectures located at numerous sites. One longstanding issue is the management of components. The complexity involved in choosing, locating, compiling, verifying, and deploying codes consisting of hundreds of independent modules can be overwhelming for beginners, and is a huge burden on developers and users. In the case of Cactus, framework-specific tools have been developed to address some of these issues, but it still suffers from being somewhat ad-hoc, difficult to maintain, and lacking in capabilities. This paper describes a dynamic framework for deploying applications that we are developing, called Ubiqis, which works automatically and on-demand. It is decentralized, requires no per-application configuration by administrative staff, and can work recursively to resolve dependencies.
