Abstract

A run-time visualization and solution-steering tool, TPview, has been developed to overcome difficulties commonly encountered with large-scale numerical simulations on high-performance parallel computer systems. TPview provides the interface between the parallel computer system and the visualization software running on a remote workstation, During the computation cycle, data distributed across multiple processors are periodically sent via sockets to the workstation for rendering., In addition, internal parameters of the simulation code can be modified using a user-defined graphical interface, enabling remote guiding of the solution procedure, It is shown that such a run-time visualization and solution-steering tool can be implemented with minimal effort from the programmer and end user. Examples are presented of the use of TPview in conjunction with a parallel multiblock flow solver and a commercial visualization package. These examples demonstrate its ability to provide greater insights for the analysis of complex flow simulations. (C) 1998 American Institute of Physics.

Parallel computing

Parallel computing is a type of computation in which many calculations or processes are carried out simultaneously. Large problems can often be divided into smaller ones, which can then be solved at the same time. There are several different forms of parallel computing: bit-level, instruction-level, data, and task parallelism. Parallelism has long been employed in high-performance computing, but has gained broader interest due to the physical constraints preventing frequency scaling.

User interface

In the industrial design field of human–computer interaction, a user interface (UI) is the space where interactions between humans and machines occur. The goal of this interaction is to allow effective operation and control of the machine from the human end, while the machine simultaneously feeds back information that aids the operators' decision-making process. Examples of this broad concept of user interfaces include the interactive aspects of computer operating systems, hand tools, heavy machinery operator controls and process controls.

Computer simulation

Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering.
