DESCRIPTION
GridRio is an initiative to create a research oriented computational grid across the state of Rio de Janeiro. The objectives include providing researchers with a realistic and practical environment (testbed) for distributed computing research and offering system administrators practical experience in managing and operated distributed computing resources. GridRio, operational since November 2002, currently employs the Globus Toolkit middleware across participating sites. Individual sites are currently working on integrating Globus with locally installed resource management software, e.g. the Sun ONE Grid Engine, openPBS etc. |

GRIDRIO
STATUS AND
SITES
|
|
The Globus Toolkit based GridRio Computational Grid is operational and available to researchers for grid related research work. Information on how to gain access to grid resources will appear here soon. We are also accepting requests for new sites to join GridRio, just send us an email.
A new Instruction Guide in portuguese (the current version is 2.4) is available for installing and configuring the Globus 2.4 software. [Although earlier versions of Globus are no longer available from the Globus Web site, our portuguese Globus version specific Installation guides (in portuguese) can still be obtained on request.] A basic Getting Started User Guide (also in portuguese) is available for GridRio users. Specific details should be obtained your local site adminstrator. Below is a list of sites which have so far offered to take part in this initiative.

ALua |
A dual programming model for developing parallel and distributed applications. |

BOSSA |
Distributed branch-and-bound algorithm with load balancing and fault tolerance capabilities for grid environments. The algorithm has already been compared with an existing sequential branch-and-bound algorithm for the Steiner Problem in graphs. Excellent speed ups are obtained using the GridRio Computational Grid (with MPICH-G2), allowing
the resolution of a number of formerly open instances from the SteinLib library in reasonable times. |
