LEGaTO organises a workshop on Low-Energy Heterogeneous Computing

The 'Low-Energy Heterogeneous Computing Workshop', collocated with FPL 2020, was held by LEGaTO on 4 September 2020 as the project’s final event. Over 75 people from around the globe, ranging from researchers to practitioners and industry representatives, attended the presentations and joined the discussion.

The objective of the workshop was to apply the optimization low-energy techniques used in each of the LEGaTO use cases to other stakeholders and present the project’s latest scientific results. External speakers and LEGaTO researchers came together to engage the Artificial Intelligence, Smart City, Smart Home, Healthcare and IOT communities to evangelize the low-energy optimization techniques that have been developed during the lifetime of the LEGaTO project.

Miquel Pericàs (Chalmers University of Technology), FPL 2020 co-organiser and Chalmer's LEGaTO Principal Investigator, said:

“The LEGaTO workshop was a great way to celebrate the achievements of the LEGaTO project. It was inspiring to see such a diverse audience come together to learn about novel technologies for achieving higher energy efficiency. We are very pleased to have such a successful workshop at FPL 2020”.

Osman Unsal group manager for the Department of Computer Architecture and Parallel Paradigms at the Barcelona Supercomputing Centre (BSC) and coordinator of LEGaTO, said:

"We are very excited to have this distinguished panel of experts to detail low-energy optimization techniques and to discuss the outcomes of the LEGaTO project and related technologies. It has been a very successful final event for the project." 

Recording of the workshop

Osman Unsal kicked off the workshop with the opening remarks and a presentation of the LEGaTO project. The keynote talk was given by Stephan Diestelhorst (Xilinx), who outlined the challenges posed by accelerators used to enhance performance and efficiency of compute, and explored different ways to tackle them. The presentation was titled The Accelerator Conundrum - and three sketches to solve it.

The programme included sessions on (please click on the titles for the slides):

1. Energy Efficiency, chaired by Jens Hagemeyer (Bielefeld University)


2. Fault Tolerance and Security, chaired by Leo Bautista (BSC)


3. AI and Smart City/Smart Home, chaired by Micha vor dem Berge (Christmann)


4. FPGAs and Programming Models, chaired by Miquel Pericàs (Chalmers University of Technology)


5. European Related Projects, chaired by Marcelo Pasin (University of Neuchâtel). Four European projects were introduced, as well as their synergies with LEGaTO:


A poster session, chaired by Behzad Salami (BSC), was also organised. 11 early career researchers were able to present their contributions to the LEGaTO project. Their poster presentations were recorded and available online in advance, and they also answered questions during the session. The most voted poster was 'RECS – Cloud to Edge Microserver Platform for Energy-Efficient Computing, by Martin Kaiser (Bielefeld University), who will be featured in an interview in the forthcoming HiPEAC info (January 2021).
