Room: 31/3-004 - IT Amphitheatre The talk will be in person and is fully confirmed to take place at the specified time. **Abstract:** As space missions grow increasingly complex, traditional homogeneous computing architectures struggle to meet the diverse and evolving demands of on-board data processing. Adaptive heterogeneous computing offers a promising solution by combining different processing elements—such as CPUs, GPUs, FPGAs, and AI accelerators—into flexible, reconfigurable systems. This talk explores how adaptive heterogeneous platforms can enhance autonomy, resilience, and performance in space applications, from real-time scientific data analysis to fault-tolerant spacecraft control. In this scenario, efficient and reliable profiling will become a critical aspects of the system. We will discuss the key opportunities this paradigm presents, including improved energy efficiency and mission adaptability, alongside the challenges limited power budgets, software complexity, and radiation tolerance. Finally, we will highlight emerging technologies and research directions shaping the future of space computing. **Speaker: Prof. Andrea Guerrieri** Andrea is a professor and researcher at the University of Applied Sciences Western Switzerland and EPFL. He is the head of the Adaptive Heterogeneous Systems Lab, specialized on adaptive and reconfigurable computing, electronic design automation for both terrestrial and space applications. He authored several dozens of papers presented at prestigious international venues such as the International Symposium of Field-Programmable Gate Arrays (ISFPGA), the Design Automation Conference (DAC), Space Computing Conference (SCC), and Quality Electronics Design (ISQED). He is also the author of a book on [System-on-Chip Design with Arm][1], and editor of a book on Applications enabled by FPGA-based technology. Andrea’s work has earned him several prestigious awards, including **Best Paper Awards** at FPL 2024, HPEC 2024, and ISFPGA 2020, held in Seaside, California. He has also received multiple **Best Paper nominations** at FCCM 2022 in New York, FPL 2022 in Edinburgh, and the European HiPEAC 2022 award. In 2021, he was recognized as a **Senior Member** of IEEE. Andrea actively serves as a Technical Program Committee (TPC) member, artifact evaluator, and session chair for key conferences such as DAC, DATE, ISFPGA, ICCD, FCCM, FPL, and ISQED. He was honored with the **Outstanding TPC Member Award** at DAC 2024 and DAC 2025 in San Francisco, California, USA. He participates in and leads multiple international projects, and he is currently collaborating with partners across Switzerland and Silicon Valley (USA) to shape the next generation of EDA tools and reconfigurable computing platforms for both terrestrial and space applications. His key collaborators include industry giants like AMD-Xilinx, NVIDIA, Arm, NASA, and CERN, but also academic institutions such as ETH Zurich, University of Geneva, and California State University. He is chair of the Onboard Computing topic for the Swiss consortium CHEESE affiliated with NASA SSERVI (Solar System Exploration Research Virtual Institute), located at AMES Research Center, Mountain View, California, USA.

Room: 31/3-004 - IT Amphitheatre The talk will be given remotely and is fully confirmed to take place at the specified time. **Abstract:** In recent years, HPC systems have become increasingly complex and heterogeneous, including CPUs and GPUs, making application development and optimization challenging. Performance models like the Cache-aware Roofline Model (CARM) offer effective guidance by providing insights into bottlenecks that limit the application’s ability to reach the system’s maximum performance. The focus of this talk is the CARM Tool, which was developed to provide CARM support, not only to all major CPU architectures and ISAs, i.e., x86 (Intel, AMD), ARM, and RISC-V, but also to GPUs (NVIDIA). The CARM tool also covers specialized accelerators for artificial intelligence, such as the NVIDIA Tensor Cores, for the performance and efficiency characterization of deep learning workloads. The proposed tool includes automatically generated microbenchmarks, specifically tailored to cover both computational units and all memory hierarchy levels. Additionally, in this talk, I will showcase the deployment of CARM in the EuroHPC centers and present a short tutorial on the tool usage. **Speaker: Prof. Aleksandar Ilic** Aleksandar Ilic (PhD’14) is an Associate Professor at the Electrical and Computer Engineering Department (DEEC) of Instituto Superior Técnico (IST), Universidade de Lisboa, and a Senior Researcher of the INESC-ID, Lisbon, Portugal. His research interests include high-performance and energy-efficient computing and modeling of parallel heterogeneous systems. He has contributed to more than 90 international journal and conference publications.
