Conclusions and drawbacks
4 Sun Servers
Scientific Linux 4.6
Two 8-nodes clusters.
Developed by IVIC (Instituto Venezolano de Investigaciones Científicas).
Used in Quantum Chemistry to solve and synthetize molecular interactions
High performance required
Parallel modules developed in OpenMPI
CATIVIC Porting to grid
Work began at the EELA-2 GridSchool at Itacuruca (Jaime Parada, Edgar
Perdomo) based on bash scripts (2008)
Enhancement of such scripts (2008 - 2009)
Web site developed (2009)
Recopilation of all CATIVIC outputs
Adding of an abstraction layer – easier for end users
Software for particles modeling, developed by S. J. Sciutto, Physics
Department, Universidad Nacional de la Plata (Argentina)
Written entirely in FORTRAN.
Intensive CPU usage for particle rain simulations
BRAMS (Brazilian Regional Atmospheric Modeling System).
Developed by a group of Brazilian institutions
Meso-scale model- Both vertical and horizontal resolution are needed for
Web Interfaces: Aires and BRAMS
Interface problems lead us to create an easy web portal for our applications.
In this case, users can avoid technical aspects, as security, command-line
instructions and so on
EasyGrid combines easy usage of Microsoft .NET GUI components, with
Linux power at the back end
Tasks: users can configure task to be launched to Grid, check for status, add
applications and new runs, and personalize both tasks descriptions and
Results can be directly downloaded in an easy way (yet gzipped)
Each user can customize its preferences, such as applications and statistics
Slow and hard gridization process, in part by middleware used
Users resistance to migration – they prefer their home clusters!
End users and developers interest groups growth too slow
EasyGrid seems to be a good alternative for users. Performance and
usability test not done yet
Platform is costly and hard to maintain without professional personnel
Lack of strong groups of users and applications at UCV for HPC – more
advertising is needed
Small group at UCV for Grid development at CCPD – but with a big heart
Porting of new applications, and development of a methodology that facilitates
Improvements of EasyGrid, specifically usability and performance test
Join of UCV to national and international grid platforms, using CLARA facilities
