Special Issue on Approximate Computing: the need for efficient and sustainable computing
提出日: 2025-01-31

Motivation and Scope

Today, computing systems face unprecedented computational demands. They serve as bridges between the digital and physical world, processing vast data from diverse sources. Our digital world is constantly producing an immense volume of data. According to recent estimates, millions of terabytes of data are created each day. To handle this immense volume of data, increasingly sophisticated and resource-constrained devices are deployed at the edge, where energy and power efficiency takes center stage. Additionally, the growth of modern AI models, particularly neural networks, has led to boundless computational and power demands. For example, GPT-3 featuring 175 billion parameters, BERT large equipped with 340 million parameters, require high energy costs for training and inferencing data. Approximate Computing (AxC) provides a promising solution: by intentionally allowing slight inaccuracies in computations, AxC significantly reduces overhead (including energy, area, and latency) while preserving practical accuracy levels. These paradigms find applications across several domains. With the intent of navigating the intricate balance between accuracy, reliability, and energy efficiency, exploring Approximate Computing (AxC) techniques becomes crucial.

The proposed Special Issue (SI) investigates the intersection of energy-efficient computing and accuracy of state-of-the-art workloads, shedding light on innovative approaches and practical implementations.

The potential areas of interest for the proposed SI include, but are not limited to, the following topics:

    Approximation for Deep Learning applications, including Large Language Models (LLMs)
    Approximation techniques for emerging processor and memory technologies
    Approximation-induced error modeling and propagation
    Approximation in edge computing applications

Special Issue on On-device Artificial Intelligence solutions with applications on Smart Environments
提出日: 2025-02-25

Motivation and Scope

The recent advancements in Artificial Intelligence (AI) and the increasing computational power acted as catalyzer for the widespread diffusion of Intelligent Cyber Physical Systems (ICPSs) as a novel way to run smart applications with a “reasoning” component. Unfortunately, the limited hardware capabilities of these devices pose significant limitations on the complexity of the tasks and Deep Learning models that can be run effectively. During the years, solutions like weights compression or quantization have been proposed to address this issue, but they usually require a careful tuning and most of the time they consist in a post-training operation. From the very beginning, the training of complex Deep Learning models has always been reserved to powerful machines with large computing capabilities (typically identified in the Cloud), limiting the Edge only to the inference. However, these solutions do not work especially when latency, security, and high customization aspects become key prerequisites. In such a context emerges the need of novel methods to deliver the intelligence into an embedded system without the data leaving the device. Originally born as a complementary technology, On-device AI is expected to become a hot topic in the next years as a new paradigm where both training and inference processes are performed on the same device. If on the one hand, the possibility to run intelligent algorithms on these systems is a challenging task, on the other the benefits in terms of response time and energy efficiency derived from this technology are going to be the foundations for a novel type of “reasoning” systems. To this aim novel architectures and frameworks should be explored to enable the access to AI based tailored services. Considering a scenario where the Edge would potentially store sensitive data (that should never travers the Internet), it is evident that these devices could become the target of attacks by malicious users. In this sense, privacy and security aspects represent another key elements to be carefully considered and implemented.

This special issue has the goal to promote original, unpublished, high-quality research about On-device AI solutions applied to the Smart Environments and Industry 4.0 contexts.

The topics of interest include, but are not limited to:

    On-device training solutions
    On-device AI applications
    Federated Learning training and inference strategies on Edge devices
    AI Intelligent Systems
    AI for Microcontrollers
    AI applications at the Edge
    AI methods for Industrial applications

Special Issue on Advances in Quantum Computing: Methods, Algorithms, and Systems Vol II
提出日: 2025-02-28

Motivation and Scope

Quantum computing (QC) is an emerging, potentially disruptive computational model gaining strong momentum in the scientific community. QC research covers multiple intertwined aspects, ranging from potential hardware design and different implementations and technologies to the quantum software stack, including compilers, high-level programming abstraction, tools, and quantum algorithms and applications. With the advent of the QC systems openly available to the scientific community and the first promising benchmarks showing quantum advantage, the effort towards practical, yet daunting, issues such as the hardware and software integration of QC systems into the HPC infrastructure, the QC acceleration of classical scientific and industrial applications and workflows (e.g., quantum chemistry and quantum simulations, drug discovery, computational fluid dynamics) intensified in the last few years, leading to several proposed approaches to harness the QC power.

From a high-level point of view, the Quantum Processing Unit (QPU) can be seen as a specialized device to accelerate certain applications that exploit algorithmic formulations to use quantum state superposition, entanglement, quantum tunneling, or interference. QPUs can be deployed today as an accelerator for the first time in HPC systems. While extensive experience has been gained to operate and exploit other accelerators, such as GPUs that today provide the backbone of HPC systems, we face challenges fundamentally different from the past. These challenges include the usage of technologies, often requiring exceedingly low temperature and shielding, the need for interfacing the classical and quantum systems, the development of error correction algorithms, and quantum computer simulators to test the results of QC systems and QC real-world use cases and applications still in their infancy.

This special issue aims to collect influential contributions to address these challenges of quantum computing (QC). This special collection invites papers targeting the following topics:

    Integration of QC systems into HPC software and hardware infrastructure
