Almost 1000 years old, the University of Bologna (UNIBO) is known as the oldest University of the western world. Nowadays, UNIBO still remains one of the most important institutions of higher education across Europe and the second largest university in Italy with 11 Schools, 33 Departments and about 84.000 students; it is organised in a multi-campus structure with 5 operating sites (Bologna, Cesena,Forlì, Ravenna and Rimini), and, since 1998, also a permanent headquarters in Buenos Aires.

With regard to the capability of attracting funding, UNIBO is very active both at National and European level. At European level, with 87,8 million Euros from FP7 and other EU funded programs (274 projects funded in 2007-2013; in 58 of them UNIBO was coordinator) UNIBO is the second Italian university for the attractiveness of European funding for research, 37thin the European ranking of institutions of higher education.In Horizon 2020, UNIBO is involved in 44 funded projects – in 8 of them UNIBO is coordinator – with 14.49 million Euro.UNIBO is also affiliate partner of the EIT KIC “EIT ICT Labs”. At National level UNIBO ranks second for competitive research funding from the Italian Government.

At the University of Bologna, activities related to European funding programs are supported by the European Research and Innovation Office. With about 30 people, organized in 4 thematic units plus another unit specifically devoted to ERC and Marie Curie programs, the office assists research groups in the whole project lifecycle: networking and lobbying, consortium building, proposal preparation, negotiation and project management. The European Research and Innovation Office steadily cooperates with the Knowledge Transfer Office, supporting the IP protection and exploitation, and the take up and commercialization of project results.

With regard to the international reputation, UNIBO has been awarded the use of the logo “HR Excellence in Research” and is among the top 5 Italian universities in the mainInternational rankings,e.g., 2nd Italian university (75th position) in the international QS – World University Rankings of the world best universities; 4th Italian University (201-250th position) int heWorld University Rankings.

The activity of the University of Bologna will be conducted within Department of Computer Science and Engineering (DISI)and the Department of Electrical, Electronic and Information Engineering (DEI). DISI is one of the strongest centres for computer science and engineering research, covering such diverse areas as artificial intelligence, autonomic and complex systems, bio-informatics, middleware systems, networks, programming languages, formal methods, hardware and software systems and their applications in medicine, energy, environment and society, to cite just a few.DEI is one of the largest department in UNIBOs with an excellent research profile,attracting more than 25% of UNIBOs overall EU funding. Within DEI, the research activity of the group in OPRECOMP are carried out by the Energy-Efficient Embedded Systems Lab,covering areas related to compilers,programming models and architectures in the domain of embedded-energy-efficient multi- and many-core systems on a chip.

 

Contribution to OPRECOMP

For the OPRECOMP project, UNIBO will be involved in the definition of the system architecture which exploits a set of hardware knobs provided at the architectural and circuit levels to tune the transprecision policies of the architecture components (e.g., CPUs, functional units, communication subsystem and memory hierarchy). This will be achieved by providing a full software framework with two main goals:

  1. hiding the complexity of the transprecision analysis to the final user
  2. supporting the heterogeneity of the OPRECOMP target platforms that range from low-power mW-scale to high-performance MW-scale computing.

UNIBO will mainly contribute to WP6 where the software environments and tools such as compilers and programming model support, runtime support are developed. In the same WP, machine learning will be used to characterize the application error on the basis of approximation decisions, and optimization techniques will be employed to take off-line and on-line decisions on application allocation, scheduling and approximation.
UNIBO will also work on WP7 by defining some applications and micro-benchmarch and on WP8 by providing system integration solutions demonstrating the effectiveness of the proposed approaches on applications provided by WP7. Smaller contributions will also be provided on WP3 and WP9.
