VoD




Application Status Report: VoD









• First ported version to the EELA infrastructure during the 1st Grid School

• Client requests come from UIs

• Videos and data are stored on storage servers

• RIO server installed on entry points of the EELA infra-structure

• Whenever a request is made, the RIO server retrieves the video/data from the storage server

• Client can then see the video/data

Users only need to search for content at one central location (portal).

Content still resides on content owners’ servers, fully controlled and managed by them.

Increase chances the content being discovered as it is being properly described in the metadata.

Increase number of visitors to content owners’ portals/websites.

Users can still directly access the content owners’ portals/websites.

Applications Status Report

SATyrus




SATyrus:

• SATisfiability-based, neuro-symbolic architecture;

• Exact formulation synthesizer.

Target Problem, e.g., colouring

Constraints Modeling

SATyrus compiler

Energy Function

Optimizer, e.g., stochastic HONNs

Global/Local optima

Application Status Report: SATyrus




Application Status Report: SATyrus

• First version ported during the 1st Grid School

multistart metaheuristics: multiple networks produced by SATyrus, each mapped to the available grid machines, each starting from a different point in the state space of solutions;

• Future Work Plan
