Scuola Superiore Sant'Anna

The Sant'Anna School of Advanced Studies (Scuola Superiore Sant'Anna)

The Sant'Anna School of Advanced Studies (http://www.sssup.it) in Pisa is an autonomous, special-statute university that operates in the field of applied sciences: Economic Sciences, Legal Sciences and Political Sciences for the Class of Social Sciences, and Agricultural Sciences, Medical Sciences, and Industrial and Information Engineering for the Class of Experimental Sciences. It aims to:

  • Promote the development of culture, scientific and technological research and innovation.
  • Offer and oversee quality undergraduate, graduate and continuing education;
  • Assure continuous interaction between research and educational activities for high quality university studies.

The RETIS Lab profile

The Real-Time Systems (RETIS) Group at the Sant'Anna School of Advanced Studies (SSSA) is one of the world's leading research teams in the area of embedded real-time systems, time critical scheduling algorithms, advanced operating systems and adaptive resource management. The group was established in 1993 and is now composed of about 30 people (http://retis.sssup.it).

The RETIS group has been involved in many European research projects related to several aspects of real-time systems, including scheduling, operating systems support for embedded systems, development tools for real-time applications, and real-time control software. Some of the projects include FIRST – “Flexible Integrated Real-time Systems Technology” (IST-2001-32467), FABRIC – “Federated Applications Based on Real-time Interacting Components” (IST-2001-37167). RETIS also implemented real-time components in the Linux kernel within the OCERA EU project – “Open Components for Embedded Real-time Applications” (IST-2001-35102), extending them to the management of disk scheduling and coordinated adaptation of reservations on multiple resources within the FRESCOR EU project (FP6/2005/IST/5-034026). Another relevant activity of the RETIS group is the development and maintenance of a novel real-time kernel, called SHARK (http://shark.sssup.it) for integrating tasks with hard and soft real-time constraints.

Giorgio Buttazzo, who coordinates the RETIS lab, is also responsible for the Adaptive Real-Time activity in the European Network of Excellence ARTIST2, coordinating ten European research groups working in this area.
