The grid in Venezuela

• The connection between those institutes at a
  speed of 32 MB/s is part of the REACCIUN2 project
  sponsored by the Ministry of Science and
  Technology (Ministerio del Poder Popular de
  Ciencia y Tecnología).
• The software that manages communications in the
  grid environment (middleware) on GridVenezuela is
  gLite
• At present IVIC contributes with a 9-node cluster
  to GridVenezuela and will expand this to 64 nodes
  in the near future. The operating system that is
  installed is Scientific Linux 3.0.7.

The E-infrastructure shared between Europe and
Latin America

• Goal
• To build a bridge between consolidated
  e-Infrastructure initiatives in Europe and
  emerging ones in Latin America.
• Objectives
• Establish a human collaboration network between
  Europe and Latin America
• Setting a pilot e-infrastructure in Latin America
• Identifying and promoting a sustainable framework
  for e-Science in Latin America

• The application AUTOSTRUCTURE

AUTOSTRUCTURE is an updated and extended version
of the atomic structure code SUPERSTRUCTURE,
widely used by the international community of
atomic physics, astrophysics, plasma physics,
laser physics.

• Download the software
• Configure the parameters
• Compile the application
• Create the input file

./autos.x lt file.in

• The application AUTOSTRUCTURE

The original application advantages and
disadvantages

• Advantages
• Fully controlled by the user
• Source code available for modifications
• Shell speed

• Disadvantages
• Difficult to learn and configure
• Related to user hardware limitations
• Primitive user interface
• Locally accessible
• Unfriendly input/output files
• Centralized data administration

12

• The application AUTOSTRUCTURE

Web Interface

• Download the software
• Configure the parameters
• Compile the application
• Create the input file

13

• The application AUTOSTRUCTURE

Web Interface advantages and disadvantages

• Advantages
• Easy to learn and use (reduce the learning
  curve)
• No configuration required
• Massive resources
• Globally accessible
• Friendly set up of input files
• Organized results table (output files)
• Remote and distributed data administration
• Permanent data storage

• Disadvantages
• Change resistant (many traditional user)

• Conclusions and Future Work

• The implementation of a grid environment enables
  the use of powerful remote scientific
  installations.
• The use of web portals facilitates the use of
  applications on a grid environment for the final
  user.
• Future work Improve the grid interface for
  AUTOSTRUCTURE job history management on grid
• Future work Integrate R-MATRIX software package
  in the grid environment.
