- d640e4aa-63bf-4aac-b579-eef79f1da470 description "The term "Urban Heat Island" (UHI) effect describes the phenomenon where urban environments exhibit higher air temperatures than their rural counterparts, a difference that is especially pronounced at night. This effect arises from the greater capacity of urban materials and man-made structures, such as buildings and pavements, to absorb, store, and then re-radiate heat compared to natural landscapes. First identified over two centuries ago, the UHI effect is subject of research to understand, measure, and mitigate its impacts on society, economic activities, and public health. Although traditionally the prerogative of specialists, the UHI is also attracting increasing interest among citizens. However, not all have the necessary technical expertise or infrastructure access to source relevant data (from in-situ measurements, satellite remote sensing, or numerical models), process it efficiently, synthesize it and interpret the changes over time or between different locations. The UHI-Stream tool was specifically developed to bridge this gap and quickly analyze temperature differences between two points anywhere on Earth's by leveraging EGI compute and storage resources (owned by CESNET) and ERA5-Land reanalysis data (available from 1950, as part of the Copernicus Climate Change Service). The corresponding hourly 2m air temperatures are streamed from S3 buckets, processed on-the-fly and visualized as annual heat-maps or animations spanning user-defined time-frames. Conveniently hosted on [RoHub][1] as a FAIR (Findable, Accessible, Interoperable, and Reusable) Executable Research Object, UHI-Stream is expected to be further converted into a Galaxy tool with a Graphical User Interface as part of the [EuroScienceGateway][2] project, potentially incorporating additional features to help users pinpoint representative urban and adjacent rural areas, or account for more grid cells. In summary, UHI-Stream is poised to become a valuable asset in urban climatology studies, enabling easier identification of UHI patterns and estimating climate impacts on a regional scale. The tool’s versatility in analyzing any two geographic points enhances its usefulness beyond the mere urban-rural context, allowing for comparative analyses of temperature changes across diverse locales, regardless of their relationship.

- 2205.00319 description "There is a consensus that Urban Heat Island phenomenon - UHI occurs in every large city. This effect is characterized by higher air temperatures in cities than in the neighboring countryside at night. However, to date, there has been no systematic study on the Fortaleza case, the Brazil’s 5th largest city. By the comparison between screen-level air temperature measured by two automatic weather stations, one located in the city and the other in the neighboring region, this work shows the occurrence of the UHI in Fortaleza, even during the rainy season. In an attempt to find some effect of the UHI on precipitation (and vice-versa), historical series of air temperature and precipitation were analyzed from 1966 to 2020. Besides the considerable increase in air temperature over the years, a slight downward trend was observed in UHI and even more in precipitation between the hours of 15:00 and 21:00 (local time). However, one believes that these trends may be related to climate change at large scale rather than an urban scale." assertion.

The tool predominantly utilizes ERA5-Land meteorological reanalysis data to characterize and quantify the UHI effect. It will also offer a straightforward approach to examining the temperature contrasts between urban and surrounding rural areas either defined by the user or delineated with the aid of satellite data to ensure accurate urban-rural categorization. The interactive interface of the tool is meant to ensure that users can engage with the data without requiring specialized technical knowledge, promoting environmental awareness and facilitating informed decision-making for heat mitigation and urban planning. The objective of the integration with the UseGalaxy.eu platform is to democratize access to complex climate data, fostering community-driven solutions to combat the challenges posed by increased urban temperatures." assertion.

While Howard is best known for his work on clouds1, he was also the first to recognise the effect that urban areas have on local climate. Much of his studies on climate, including his description, analysis and observations, are contained in CLIMATE , which can reasonably claim to be the first textbook on climatology. Despite its title, the majority of the book is concerned with weather and climate in general, rather than that of the London metropolis. Nevertheless, one hundred and thirty-two years after its publication, Chandler dedicated his study of the spatial and temporal character of metropolis’ climate to Luke Howard (1772-1864), whom he described as the pioneer of urban climatic studies." assertion.

- 3491418.3530773 description "ABSTRACT The Slingshot interconnect designed by HPE/Cray is becoming more relevant in High-Performance Computing with its deployment on the upcoming exascale systems. In particular, it is the interconnect empowering the first exascale and highest-ranked supercomputer in the world, Frontier. It offers various features such as adaptive routing, congestion control, and isolated workloads. The deployment of newer interconnects raises questions about performance, scalability, and any potential bottlenecks as they are a critical element contributing to the scalability across nodes on these systems. In this paper, we will delve into the challenges the slingshot interconnect poses with current state-of-the-art MPI libraries. In particular, we look at the scalability performance when using slingshot across nodes. We present a comprehensive evaluation using various MPI and communication libraries including Cray MPICH, OpenMPI + UCX, RCCL, and MVAPICH2-GDR on GPUs on the Spock system, an early access cluster deployed with Slingshot and AMD MI100 GPUs, to emulate the Frontier system." assertion.
- 364-CHEP23_Paper_ApptainerWithoutSuid.pdf description "Abstract. Apptainer (formerly known as Singularity) since its beginning implemented many of its container features with the assistance of a setuid- root program. It still supports that mode, but as of version 1.1.0 it no longer uses setuid by default. This is feasible because it now can mount squashfs filesystems, ext3 filesystems, and overlay filesystems using unprivileged user namespaces and FUSE. It also now enables unprivileged users to build containers, even without requiring system administrators to configure /etc/subuid and /etc/subgid unlike other “rootless” container systems. As a result, all the unprivileged functions can be used nested inside of another container, even if the container runtime prevents any elevated privileges. As of version 1.2.0 Apptainer also supports completely unprivileged encryption of Singularity Image Format (SIF) container files. Performance with a particularly challenging HEP benchmark using the FUSE-based mounts both with and without encryption is essentially identical to the previous methods that required elevated privileges to use the Linux kernel-based counterparts." assertion.
- 8950983 description "Abstract: Linux Containers with the build-once run-anywhere principle have gained huge attention in the research community where portability and reproducibility are key concerns. Unlike virtual machines (VMs), containers run the underlying host OS kernel. The container filesystem can include all necessary non-default prerequisites to run the container application at unaltered performance. For this reason, containers are popular in HPC for use with parallel/MPI applications. Some use cases include also abstraction layers, e.g. MPI applications require matching of MPI version between the host and the container, and/or GPU applications require the underlying GPU drivers to be installed within the container filesystem. In short, containers can only abstract what is above the OS kernel, not below. Consequently, portability is not completely granted. This paper presents the experience of PRACE (Partnership for Advanced Computer in Europe) in supporting Singularity containers on HPC clusters and provides notes about possible approaches for deploying MPI applications using different use cases. Performance comparison between bare metal and container executions are also provided, showing a negligible overhead in the container execution." assertion.
- 18d3e6d6-e559-4e43-b464-55275bd14708 description "The modern form of containers, as popularly known through platforms like Docker, Singularity (Apptainer), Podman or Charliecloud, to cite only a few, began to take shape over a decade ago. However, the fundamentals behind containerization and actual benefits of containers in scientific computing remain largely unclear to a vast majority of users. In fact, there is a significant gap between simplistic “Hello world” examples found online and real scientific applications. Rumors suggest that achieving satisfactory performance on supercomputers across multiple nodes is impossible. This paper describes how to leverage the full potential of high-speed networks for inter-node communications with UCX on Fram and Betzy (from the Norwegian national e-infrastructure). It is then explained how to achieve near-native performance on Lumi (EuroHPC's flagship) despite its OFI "Slingshot-11" interconnect and proprietary library. Results obtained in the standard OSU Micro-benchmarks tests for latency and bandwidth and with a fully-fledged climate model show that containerized applications work just as well as "bare-metal", are portable and provide bit-for-bit reproducibility on different platforms. Containers are therefore highly recommended to minimize deployment and porting issues \emph{i)} for AaaS (Applications as a Service) coming with all the necessary software environment (rather than source code only); and \emph{ii)} so that HPC users do not have to rely on anybody to install what they need and can be operational within minutes whilst still getting top performance." assertion.

A novel GBM approach is proposed in this paper to establish a digital twin model for voyage performance prediction. The weather hindcast data are introduced to enrich noon reports (NR) and automatic identification system (AIS) datasets, which are split into training and validation sets to develop GBM. The NR and AIS datasets collected from a 57000DWT bulk carrier are used to demonstrate the fidelity and capability of the proposed GBM. The voyage performance prediction from the GBM shows better accuracy than those from pure WBM or pure BBMs. An arrival time forecast and a weather routing showcase are also presented to demonstrate the application effects of GBM. The proposed GBM provides a satisfying prediction of ship speed and fuel consumption without mandatory sensor-collected data, thus applicable for a varity of vessels. In those cases where more sensors are available onboard, the proposed approach can incorporate sensor data to improve the model accuracy further." assertion.

Oak Ridge National Laboratory (ORNL) and Los Alamos National Laboratory (LANL) are collaborating on porting and optimizing Open MPI and related components for use on HPE Cray EX systems, with a focus on the DOE Frontier and Aurora exa-scale systems. A key component of this effort involves development of a new LinkX Open Fabrics Interface (OFI) provider. In this paper, we describe enhancements to Open MPI, OpenPMIx runtime components, and the LinkX OFI provider. Performance results are presented for point to point and collective communication operations using both the vendor CXI provider and the LinkX provider, including results obtained using GPU accelerators. Recommended deployment options for EX systems will be discussed, along with future work." assertion.

- s11390-023-2907-5 description "Abstract The Slingshot interconnect designed by HPE/Cray is becoming more relevant in high-performance computing with its deployment on the upcoming exascale systems. In particular, it is the interconnect empowering the first exascale and highest-ranked supercomputer in the world, Frontier. It offers various features such as adaptive routing, congestion control, and isolated workloads. The deployment of newer interconnects sparks interest related to performance, scalability, and any potential bottlenecks as they are critical elements contributing to the scalability across nodes on these systems. In this paper, we delve into the challenges the Slingshot interconnect poses with current state-of-the-art MPI (message passing interface) libraries. In particular, we look at the scalability performance when using Slingshot across nodes. We present a comprehensive evaluation using various MPI and communication libraries including Cray MPICH, OpenMPI + UCX, RCCL, and MVAPICH2 on CPUs and GPUs on the Spock system, an early access cluster deployed with Slingshot-10, AMD MI100 GPUs and AMD Epyc Rome CPUs to emulate the Frontier system. We also evaluate preliminary CPU-b:ed support of MPI libraries on the Slingshot-11 interconnect." assertion.
