domains can easily team up to perform computational thinking on challenging scientific
problems by sharing their computational software tools and elevating experimental
datasets to scientific knowledge and innovative theories. Our paper deals with the
position of visualization as one of the main components of scientific gateway. The
scientific web portal - gateway cumulate all types of visualization . This paper describes
VT for Earth science and for astrophysics, in which is cumulate all types of
visualization .
Visualization tool is a part of gateway and proposes a new web based application
framework for Earth science and astrophysics environment. The framework including
the can import the astronomy specific workflow scripts easily can generate web
appliance for running astronomical application workflows and visualization the
outputs results directly from workflow execution, online visualization through their
web browsers.
2 Visual Representation of Datasets
Simulation and execution with a huge data usually spend long execution time. Good
solution for execution is represented by grown in platforms as is grid, HPC, cloud or
cluster infrastructures. In each of infrastructures visualization has the main position as
a way to control the execution process. Visual control has in all infrastructures very
useful position. The modal parametric studies applications include, for example,
astronomical simulations. The simulation was realized as a sequence of parameter
studies, where each sub-simulation was submitted to the grid as a separate parameter
study. The job management was rather time consuming due to the analysis of failed
jobs and to their re-submission.
Visualization is included as a visual control process. Client asks for visualization is
a “visualization client”. Output data on the storage element are the inputs data for
visualization jobs. Visualization workers are to modify data to the formats, which can
be visualized, but also to prepare the typical visualization scenes. Client can render
such scenes on the browser, can make the visual control and modify executions. For
example, to immediately understand the evolution of the investigated proto-planetary
disc we have developed a Visualization Tool (VT). The VT is composed of several
modules, which are responsible for creating scenes and converting data to the
“visualize” format. The VT is designed as a plug-in module. The components
generating rendering scenes are easy to exchange, according to the requirements of
the given application. In case of our gridified application the output data of the
simulation located on the SE can be used directly as the input for the VT. The final
product of the VT includes a set of files containing data in the VRML (Virtual Reality
Modeling Language) format. These output files can be rendered by many available
VRML web-browsers. The whole visualization process is maintained through
visualization scripts, whose basic function is invoking the individual VT components
in successive steps, transferring data, and handling error events. The script is written
using the Bourne shell scripts and all VT modules are implemented in the C++
language. The VT can be embedded into the framework described above, or can be
used separately as a stand-alone program. By using the on-line VT the client can stop
the execution process, change the input parameters and restart the execution process
