The paper describes TENT, a component-based framework for the integration of technical applications. TENT allows the engineer to design, automate, control, and steer technical workflows interactively. The applications are therefore encapsulated in order to build components which conform to the TENT component architecture. The engineer can combine the components to workflows in a graphical user interface. The framework manages and controls a distributed workflow on arbitrary computing resources within the network. Due to the utilization of CORBA, TENT supports all state-of-the-art programming languages, operating systems, and hardware architectures. It is designed to deal with parallel and sequential programming paradigms, as well as with massive data exchange. TENT is used for workflow integration in several projects, for CFD workflows in turbine engine and aircraft design, in the modeling of combustion chambers, and for virtual automobile prototyping
In the AMANDA project a component-based framework for the integration of coupled technical applications, running distributed in a network, is developed. It is designed to deal with parallel and sequential programs and massive data exchange between the integrated programs. Two pilot applications will be implemented to show the feasibility of the chosen approach: a trimmed, freely flying, elastic airplane and an aircooled turbine. Beside using the integration systems, the MpCCI 1 library is used for the coupling of the codes, each simulating single physical processes.1 MpCCI is a trademark owned by GMD.
A method is described to solve the systems of tridiagonal linear equations that result from discrete approximations of the Poisson or Helmholtz equation with either periodic, Dirichlet, Neumann, or shear-periodic boundary conditions. The problem is partitioned into a set of smaller Dirichlet problems which can be solved simultaneously on parallel or vector computers leaving a smaller tridiagonal system to be solved on one of the processors,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
