Advancing Cloud Computing Capabilities on gem5 by Implementing the RISC-V Hypervisor Extension
George-Marios Fragkoulis, Nikos Karystinos, George Papadimitriou +1
This paper presents the implementation and evaluation of the H (hypervisor) extension for the RISC-V instruction set architecture (ISA) on top of the gem5 microarchitectural simula…
Security and RAS in the Computing Continuum
Martí Alonso, David Andreu, Ramon Canal +10
Security and RAS are two non-functional requirements under focus for current systems developed for the computing continuum. Due to the increased number of interconnected computer s…
Invited: Neuromorphic architectures based on augmented silicon photonics platforms
Matěj Hejda, Federico Marchesin, George Papadimitriou +6
In this work, we discuss our vision for neuromorphic accelerators based on integrated photonics within the framework of the Horizon Europe NEUROPULS project. Augmented integrated p…
DRAM Errors and Cosmic Rays: Space Invaders or Science Fiction?
Isaac Boixaderas, Jorge Amaya, Sergi Moré +7
It is widely accepted that cosmic rays are a plausible cause of DRAM errors in high-performance computing (HPC) systems, and various studies suggest that they could explain some as…
Vitamin-V: Expanding Open-Source RISC-V Cloud Environments
Ramon Canal, Stefano Di Carlo, Dimitris Gizopoulos +12
Among the key contributions of Vitamin-V (2023-2025 Horizon Europe project), we develop a complete RISC-V open-source software stack for cloud services with comparable performance…
