A Component Based Graphical Parallel Programming Approach for Numerical Simulation Development

Building massively parallel numerical simulations is not easy due to lasting changes of parallel programming models and various software technologies needed. We develop a component based graphical parallel programming approach to lower the difficulties of coding applications in scientific and engineering computing and support rapid development of large scale simulations basing on a domain specific framework. Parallel applications can be constructed simply by configuring components and assembling them in predefined flowcharts interactively. Large part of codes is auto generated from the graphical configuration for an application. The approach facilitates the rapid design and development of parallel numerical simulations by shielding many knowledge and technologies required from domain experts. Real applications demonstrate that the approach for developing complex numerical is both practical and efficient.
