But efficient DSMs are needed because they can significantly simplify the implementation of complex distributed algorithms. This paper discusses implications of the many-core evolution and derives a set of reusable elementary operations for future software DSMs. These elementary operations will help in exploring and evaluating new memory models and consistency protocols.

Unlike performance analyses, however, power and energy measurements of heterogeneous systems are difficult to conduct. Especially at the system-software level, performing power and energy measurements remains challenging. Yet, such measurements are essential to improve software components for low power and high energy-efficiency.In this paper, we analyze and discuss the power and energy characteristics of several heterogeneous systems with up to 20 cores (160 hardware threads) and 1 TB of main memory. For the analyzed systems, we outline challenges regarding power and energy measurements and show ways to overcome limitations (i.e., sampling constraints). To improve the current state of the art in power and energy measurements at the system-software level, we present the design and implementation of PINPOINT, an energy-profiling tool which unifies different power and energy measurement interfaces.

In this work we present a first principle calculation for the Ge(001) surface without and with tin impurities incorporated into the top surface layer. By mapping the system onto an Ising-type model, with interaction constants taken from density functional theory, the stability of the surface reconstructions under the influence of different concentrations of tin impurities is explored. This approach allows us to simulate the possible phase transitions for the different surface reconstructions including the local structure around the tin impurity atoms. In addition, we compare our theoretical results with experimental STM images on clean and Sn-doped Ge(100) surfaces.

Nowadays we can repeat this approach with NVRAM, but with terabytes of main memory on a completely different scale and with parts of the operating-system state stored in volatile CPU caches. In this paper, we discuss our experiences of running large modern operating systems including their applications entirely in NVRAM. We adapted stock Linux and FreeBSD kernels to work exclusively with NVRAM by hiding all DRAM from the kernels at boot time to establish a realistic performance baseline without changing anything else. Following this entirely NVRAM-agnostic approach, we could observe an effective performance penalty of a factor of about four, but only negligible increases in whole-system power draw. For our system with two CPU sockets and 56 cores total, we also observed a reduction in power draw in several scenarios. Due to prolonged execution times, the energy consumption increased as well for these measured workloads. While this might be discouraging at first sight, this result was achieved without any performance tuning as to the specific characteristics of today’s NVRAM technology. Therefore, we are also discussing means to mitigate the observed shortcomings by integrating NVRAM appropriately into the memory hierarchy of future robust persistent systems.

Future computing systems will have to contend with byte-addressable and cache-coherent main memory that is highly diverse, either in terms of the fundamental performance characteristics of its underlying memory technology, or due to the fact that CXL.mem will allow accessing homogenous but remote memory. The VM (Virtual Memory) subsystems of today have been empirically optimized over decades, but were designed for a single tier of main memory only. While recent approaches that integrated tiered memory have focused on better memory access metrics to improve page placement strategies, we seek to leverage the proven heuristics that are already in place. In times of high load we assign pages from slower memory, demote inactive pages according to standard page replacement strategies and use lazy page promotions when sufficient resources are available again to retain the inherently high reactivity of demand paging with regard to working set changes. We integrate these mechanisms into the VM subsystem of a full-featured mainstream operating system (FreeBSD) with minimal adaptations. The resulting multi-tier VM system runs in a stable and efficient manner under high stress even with highly unfavorable work loads.

T1 - PYROPHOB – A post-fire ecosystem research project to inform management for resilient forest development BT - PYROPHOB – Ein Ökosystemforschungsprojekt auf Waldbrandflächen als Grundlage für das Management einer resilienten Waldentwicklung T2 - Tuexenia N2 - PYROPHOB (fire-resistant) is the name of an interdisciplinary research project that is running for five years from 2020 to 2025. In this project, eight institutions are investigating the ecological effects of wildfires and subsequent forest management strategies in pine forests (plantations) in Brandenburg (NE Germany), with the aim of formulating practical recommendations for managing fire-prone forests and the effective restoration of post-fire forest areas. We provide a brief overview of what is known about the effects of wildfire on abiotic and biotic parameters in temperate pine forests, as well as the effects of silvicultural treatments. To date, we know little about how different components of biodiversity are linked in post-fire forest ecosystems and how management affects their functioning. By describing the project, we illustrate the requirements for the implementation of such an applied research project. We emphasize the importance of the study design for dealing with interdisciplinary questions and for the quantitative synthesis of research results. The project comprises a set of standardised field plots in two wildfire areas covering different post-fire management options. Fifteen study sites were established, including two reference sites in unburned pine stands, each with ten study plots as replicates. In situ nitrogen mineralisation, litter decomposition tests and soil biological activity are used for soil biological characterisation. Microclimate data is measured continuously. Standing and lying dead wood and tree regeneration are recorded as key indicators of the success of forestry treatments. Further methods com-prise terrestrial laser scanning, remote sensing techniques as well as surveys of vegetation and above and below ground biomass. Identification of fruiting body-forming fungi, phytoparasites and ectomycorrhizal fungi is supported by marker gene sequencing. Faunistic indicators comprise predatory soil arthropods (pairs of emergence tents and soil traps), saproxylic beetles (flight traps and funnel traps), moths (automated window traps), mammals (camera traps), and breeding birds (visual and acoustic observation). We discuss the strengths and limitations of the project design. We are able to systematically capture short-term temporal shifts in parameters and trends in post-fire ecosystem development. Research in a real landscape with ongoing environmental changes and interventions pres-ents challenges for experimental design, data analysis and interpretation. The drivers of ecosystem development are rarely completely independent or perfectly balanced, and lack of replication is ine-vitable. The two fires did not occur in the same year and season, resulting in different initial conditions for the colonisation of the burned areas. Finally, a large part of one study area was again affected by a fire in 2022, which destroyed direct comparability with the other sites. Despite these obstacles the project has started to generate valuable results to address management and conservation challenges.
