VizLitG: Grid Visualization e-Service Enabling Partial Dataset Transfer from Storage Elements of gLite-based Grid Infrastructure

摘要

Grid visualization e-service VizlitG is developed for Lithuanian grid infrastructure based on gLite middleware. The client–server architecture of the e-service VizLitG is based on widely recognized web standards implemented in Java EE 6 platform and GlassFish application server. VizLitG is designed for convenient access and interactive visualization of remote data files located in storage elements of gLite-based grid infrastructure. Partial dataset transfer from the experimental storage element is developed in order to reduce the communication time and achieve interactive rates. The performance of VizLitG is evaluated visualizing poly-dispersed particle systems of different sizes in a geographically distributed grid. The attention is focused on the performance of data transfer from the storage elements and its contribution to the total benchmark time. Different types of software are employed for data transfer in order to present the quantitative comparison.
