Solar Images Processing in Parallel Environment

This paper presents the PVA-BDA project (Processing, Visualization and Analysis in ParallelEnvironment of the BDA Data) that has been developed for processing of solar images that will be captured bythe BDA (Brazilian Decimetric Array), a radio telescope under development at the National Institute for SpaceResearch (INPE). In a joint effort between the Department of Computer Science at Federal University of SãoCarlos (DC/UFSCar), the Astrophysics Division (DAS) and Associated Laboratory for Computing and AppliedMathematics (LAC) at INPE, a high performance parallel system is being developed with capacity to supportrealistic applications, involving a reasonable amount of parallel processing, in order to carry out the processing,visualization and analysis of solar images captured by BDA, in real time. The aim is to create the conditions forstarting a study of the solar weather forecast. The forecast of solar explosions are important as they may causeserious perturbations in terrestrial communication systems. An application for 3D reconstruction of X-raytomographic images of the solar atmosphere was developed at DC/UFSCar. Due to the need for the 3Dreconstruction of solar magnetic structures, in real-time, this application was implemented to execute in a parallelmachine using DSPs

Visual Environment for High Performance Real-Time 3D Reconstruction

We are carrying out a development of a whole system for processing solar images in a high performance parallel system. The main objective is to create the initial conditions for studying and forecasting the solar explosions in real time. Due to the high computational costs involved in the processing, visualization and analysis of a great amount of solar images, a high performance computer system becomes necessary to carry out the forecast of solar explosions. As a joint effort between the Department of Computer Science at Federal University of So Carlos (UFSCar), the Astrophysics Division (DAS) and Associated Laboratory for Computing and Applied Mathematics (LAC) at National Institute for Space Research -- INPE, a high performance parallel system was developed with capacity to support realistic applications, involving a reasonable amount of parallel processing. The forecast of solar explosions is important as they may cause serious perturbations in terrestrial communication systems. A significant limitation for the development of parallel real-time systems is the lack of adequate programming tools, mainly for supporting the final stages of the development life cycle. This work presents a development environment, called Visual Environment for the Development of Parallel Real-Time Programs, that supports the design and implementation of parallel real-time applications executed with the support of a parallel kernel. This paper shows how this Environment was used to carry out the 3D Reconstruction of Solar Images
