Projects

MINHA - Java JVM virtualizer

MINHA is a system that virtualizes multiple JVM instances within a single JVM while simulating key environment components, thus reproducing the concurrency, distribution, and performance characteristics of the actual system. Implementation is based on Java6 and takes advantage of bytecode transformation to automatically convert application code to simulation environment.

Pastramy - Persistent and highly Available Software TRansactional MemorY (PTDC/EIA/72405/2006)

This project brings the FénixEDU team together with two research teams with a significant expertise on building replication solutions to relational and object oriented databases. This will allow the FénixEDU to get an insight on the pros and cons of existing replication techniques (both from a theoretical and a practical point of view). Reciprocally, the database replication experts will obtain an inside view of the singularities of the STM approach. The project will use these synergy to design, develop, implement and validate a persistent and highly available software transactional memory.

Portorama - Sharing georeferenced Oporto photos using P2P, GoogleMaps, GWT and AppFuse

Portorama is a platform for sharing photos of the city of Porto. Portorama is meant to foster a community willing to create a rich, comprehensive and truly diverse photo collection of Porto. Portorama enables you to georeference and arbitrarly tag your photos of Porto and share them across the community through a peer-to-peer network. The sets of shared photos are made available by the Portorama community and searchable by their localization, title, author and assigned tags. All photos are stored by the community in a fully decentralized manner and under the Creative Commons license.

P-SON - Probabilistically-Structured Overlay Networks (POSC/EIA/60941/2004)

The project will develop and implement a set of modular components for the implementation of efficient and scalable multicast protocols. These modules will offer complementary gossiping strategies as well as system diagnosis and adaptation policy modules that promote the desired structures. The usefulness of the approach will be demonstrated by implementing a scalable news dissemination application. P-SON is co-funded by FCT and FEDER.

GORDA - Open Replication of Databases (FP6-IST2-004758)

The goal of the GORDA project is to foster database replication as a means to address the challenges of trust, integration, performance, and cost in current database systems underlying the information society. This is to be achieved by standardizing architecture and interfaces, and by sparking their usage with a comprehensive set of components ready to be deployed. GORDA is Supported by the European Community under the Sixth European Union Framework Programme for Research and Technological Development, thematic priority Information Society Technologies.
