abstract = "In recent years, the volume of astronomical data is increasing due
to advances in observational astronomy and simulations. To cope
with this growth, there is a need for high performance computing
resources and efficient tools for analysis and exploitation of the
data. Moreover, while researchers develop new algorithms and
applications in astronomy, there is also a need for efficient ways
to make them available to the scientific community. Thus, it is
necessary to create the means to spread information to a wide
audience quickly and efficiently. In this scenario, Web portals
can provide a simple interface for different users to have access
to new applications running on a high performance computing
infrastructure, with no need to perform advanced installations and
settings. In this work, we present a Web portal framework for
remote execution of high performance applications in astronomy. In
this framework, a Web server deals with user interactions and
dispatches tasks to an execution server. The framework allows for
an administrator to manage applications that will be available to
users, and also deals with the registration of users interested on
running these applications. We developed this framework using the
Python programming language along with Django Web development
framework and Celery distributed task queue. The Web portal
framework has passed tests using a parallel Friends-of-Friends
application for classification of astronomical objects. For
application execution, the portal deals with operations such as
registration and activation of user accounts, dispatching requests
for the application running and obtaining input and output
files.",
