LEGaTO project draws to a close with low-energy heterogeneous computing workshop The LEGaTO project celebrated its final event, the ‘Low-Energy Heterogeneous
Computing
Workshop’, on 4 September 2020 as part of FPL 2020. The aim of the workshop was to present the optimization low-energy techniques used in LEGaTO to other stakeholders and share project’s latest results. It included a keynote talk by Stephan Diestelhorst (Xilinx), five panel sessions on the main topics of the project and a poster session. Martin Kaiser (Bielefeld University), who presented the ‘most

all applications within LEGaTO.
Within LEGaTO, I worked on t.RECS, which is short for tiny RECS. t.RECS expands the RECS portfolio previously focused on cloud and data centre to include edge computing applications. The server comes in a compact form factor and aims for a high energy efficiency and connectivity and was designed to be used in edge applications like automation, automotive or smart home/city. As a part of the hardware development, we worked as an executive member of the PICMIG committee to define the upcoming COMHPC standard, which is used for t.RECS. We succeeded in driving the standard towards LEGaTO’s goals to support heterogeneous and energy-efficient computations. What was the added value to your career of being in a panEuropean project? It was great to work in a group of such talented international scientists, who all have the common goal of improving the energy efficiency of computations in mind. Also, I gained lots of international experience by playing an active role in the standardization process of COM-HPC. But in the end, the best
