  • Four OSDI Posters from Memento, NEON, and PAVE
    Memento, NEON, and PAVE had a strong presence at HotCarbon and OSDI in Boston, MA, USA: At the HotCarbon Workshop, Benedict Herzog presented “carbond: An Operating-System Daemon for Carbon Awareness” and Sven Köhler gave a talk on “Carbon-Aware Memory Placement”. In the poster session of OSDI’23, the group of researchers from Ruhr-University Bochum, BTU Cottbus, FAU Erlangen, and HPI Potsdam was well represented with four posters: “Efficient NVRAM-Based General Purpose Operating Systems”, “Memento: Energy-Aware Memory Placement in Operating Systems”, “Quick-and-Dirty Memory Access Tracing with Instruction-Based Sampling”, and “A Cache-Stall Driven CPU Frequency Governor for Linux”.
  • ParPerOS and NEON Successful at the USENIX ATC
    No less than three papers by researchers from the SPP 2377 project ParPerOS and from the SPP-associated project NEON were accepted for presentation at the USENIX ATC in Boston, MA, USA. For ParPerOS, Lars Wrenger presented “LLFree: Scalable and Optionally-Persistent Page-Frame Allocation”, and Dominik Töllner presented “MELF: Multivariant Executables for a Heterogeneous World”. With “Luci: Loader-based Dynamic Software Updates for Off-the-shelf Shared Objects”, Bernhard Heinloth represented NEON at the ATC.` Last but not least, Lars Wrenger, Florian Rommel, Alexander Halbuer, Christian Dietrich, and Daniel Lohman received the Distinguished Artifact Award for LLFree. Congratulations!
  • PAVE Setup Replication with Memento
    In a joint effort, one SPP2377 project replicated another’s setup for validation and verification purposes. A modified FreeBSD kernel for NVRAM, brought forward by the PAVE team around Jörg Nolte (BTU Cottbus) and Wolfgang Schröder-Preikschat (FAU Erlangen-Nürnberg) was adapted to and installed on a system at Andreas Polze’s lab (HPI Potsdam, project Memento). The PAVE team adapted the stock FreeBSD kernel and bootloader to work exclusively with NVRAM by hiding all DRAM from the kernel at boot time and evaluated their implementation on an Optane PM 200 system.Same experiments and follow-up work can now be reproduced on a Optane PM … Read more
  • Best Paper Award for “Trusted Monitor” at SBESC’22
    A team of researchers including participants from the SPP 2377 project “Memento” and the SPP-associated project “NEON” was successful at the Brazilian Symposium on Computing Systems Engineering in Fortaleza: Benedikt Jung, Christian Eichler, Jonas Röckl, Ralph Schlenk, Timo Hönig, and Tilo Müller received a Best Paper Award for their paper “Trusted Monitor: TEE-Based System Monitoring”.
  • SPP 2377 starts with Kick-Off Meeting in Dresden
    With a two-day kick-off meeting on September 21./22. 2022, SPP 2377 has taken up work. The event was hosted by Wolfgang Lehner and his team at TU Dresden, who provided a warm welcome to 52 participants at the Max Planck Institute for Chemical Physics of Solids and the Faculty of Computer Science of TU Dresden. The first day started with an overview of the priority program by Olaf Spinczyk and a keynote by Dieter Kasper, who gave an introduction to persistent memory and the challenges it still imposes in the data-center, current developments around CXL, and addressed the problem of … Read more
