PT-Inovação has contracted ATNOG for two new short-term development projects. 
The first project, named "Elaboração e desenvolvimento da componente Access Network Discovery and Selection Function (ANDSF)", aims to develop an ANDSF entity, belonging to the Evolved Packet Core (EPC) of the System Architecture Evolution (SAE) from the 3GPP architecture. Moreover, the project aims to provide a flexible approach to the entity's design and development, enabling its integration into new scenarios, such as network optimization and Machine-to-Machine (M2M) mobility support processes.

The second project, named "Media Cloud" intends to develop a cloud based solution for home users to share their personal media contents stored in their iDevices (iPhone, iPad) to the MEO STB without undergoing any modification to the current STB and HomeGW. The project also intends to bridge other non Apple devices through protocols for media sharing such as uPNP/DNLA which are currently available in the latest generation gaming consoles. 

Daniel Corujo, Sérgio Figueiredo and Rui Aguiar are present at fthe 5th MEDIEVAL General Assembly, in Turin, Italy, hosted by partner Telecom Italia. The meeting will take place until February 9th.

One of the key aspects for many-core and cloud operating systems is message passing communication. The networking aspect of this mechanism requires a high degree of concurrency to handle communicating with thousands of cores simultaneously in an efficient and scalable manner. Non-blocking interfaces allows us to efficiently use a core and gives us concurrency without multiple threads, this also minimizes context switch.
We developed an asynchronous design pattern for operating systems written in C++. The framework uses only C++ language features (template metaprogramming), thus not requiring a custom compiler. The pattern provides a framework to develop and use asynchronous interfaces based on completion handlers. As the name implies, a completion handler is executed when the operation completes. The framework also provides queuing mechanism to serialize execution of handlers for synchronization purposes.
Bruno Santos just presented this work in a poster titled "Asynchronous Design Pattern for Many-Core and Cloud Operating Systems" at the 7th International Conference on High-Performance and Embedded Architectures and Compilers.
