“…Over recent years, FPGAs have been employed for several different applications such as the Internet of Things [21]- [23], wireless communications [24]- [25], network protocols [26]- [27], etc. The employment of FPGAs in HPC is relatively recent and still the subject of research and optimization.…”

“…Continuous demand for efficient computing power is pushing designers into integrating dedicated hardware components in High-Performance Computing (HPC) architectures to improve computational efficiency. Generalpurpose CPUs can delegate specific tasks to the hardware accelerator decreasing the latency of computationally demanding task such as the training of neural networks [1]- [4], video or audio processing [5]- [8], environmental forecasting [9]- [11], security algorithms [12], automotive applications [13], etc. In other scenarios, hardware accelerators are used to reduce system power consumption [14]- [15].…”

The Three Dimensional Fast Fourier Transform (3D-FFT) is commonly used to solve the partial differential equations describing the system evolution in several physical phenomena, such as the motion of viscous fluids described by the Navier-Stokes equations. Simulation of such problems requires the use of a parallel High-Performance Computing architecture since the size of the problem grows with the cube of the FFT size, and the representation of the single point comprises several double precision floatingpoint complex numbers. Modern High-Performance Computing (HPC) systems are considering the inclusion of FPGAs as components of this computing architecture because they can combine effective hardware acceleration capabilities and dedicated communication facilities. Furthermore, the network topology can be optimized for the specific calculation that the cluster must perform, especially in the case of algorithms limited by the data exchange delay between the processors. In this paper, we explore an HPC design that uses FPGA accelerators to compute the 3DFFT. We devise a scalable FFT engine based on a custom radix-2 doubleprecision core that is used to implement the Decimation in Frequency version of the Cooley-Tukey FFT algorithm. The FFT engine can be adapted to different technology constraints and networking topologies by adjusting the number of cores and configuration parameters in order to minimize the overall calculation time. We compare the various possible configurations with the technological limits of available hardware. Finally, we evaluate the bandwidth required for continuous FFT execution in the APEnet toroidal mesh network.

“…The c F is the unit cost per km for digging and installing the optical fiber. Considering conventional digging, the typical value for c F is c F ∼ = 60,000 euro per km [12]. Still, in (20), n C is the total number of new Cabinets to be added to the existing FttC infrastructure and c C is the cost per single Cabinet which includes all costs for installation.…”

“…The costs of fiber to the home (FttH) to be used for fronthauling dense/ultra-dense wireless network have been analysed in [10][11][12]. It turns out that investments can be very risky for telecom operators due to the still uncertain revenue volumes from future 5G deployments.…”

Abstract:One distinctive feature of the next 5G systems is the presence of a dense/ultra-dense wireless access network with a large number of access points (or nodes) at short distances from each other. Dense/ultra-dense access networks allow for providing very high transmission capacity to terminals. However, the deployment of dense/ultra-dense networks is slowed down by the cost of the fiber-based infrastructure required to connect radio nodes to the central processing units and then to the core network. In this paper, we investigate the possibility for existing FttC access networks to provide fronthaul capabilities for dense/ultra-dense 5G wireless networks. The analysis is realistic in that it is carried out considering an actual access network scenario, i.e., the Italian FttC deployment. It is assumed that access nodes are connected to the Cabinets and to the corresponding distributors by a number of copper pairs. Different types of cities grouped in terms of population have been considered. Results focus on fronthaul transport capacity provided by the FttC network and have been expressed in terms of the available fronthaul bit rate per node and of the achievable coverage.

The COVID-19 pandemic has severely affected the lives of people worldwide, and consequently, it has dominated world news since March 2020. Thus, it is no surprise that it has also been the topic of a massive amount of misinformation, which was most likely amplified by the fact that many details about the virus were not known at the start of the pandemic. While a large amount of this misinformation was harmless, some narratives spread quickly and had a dramatic real-world effect. Such events are called digital wildfires. In this paper we study a specific digital wildfire: the idea that the COVID-19 outbreak is somehow connected to the introduction of 5G wireless technology, which caused real-world harm in April 2020 and beyond. By analyzing early social media contents we investigate the origin of this digital wildfire and the developments that lead to its wide spread. We show how the initial idea was derived from existing opposition to wireless networks, how videos rather than tweets played a crucial role in its propagation, and how commercial interests can partially explain the wide distribution of this particular piece of misinformation. We then illustrate how the initial events in the UK were echoed several months later in different countries around the world.
