Special Issue on Cache Coherent Interconnects and Resource Disaggregation Techniques
提出日: 2024-12-01

In the era of exponential data growth, modern data centers and large-scale computing environments are challenged by the limitations of traditional, monolithic system designs that tightly integrate compute, memory, and storage resources. These conventional, all-integrated systems confront significant difficulties including resource over-provisioning, under-utilization, and hitting the memory capacity wall, highlighting the urgent need for innovative architectures. Resource disaggregation emerges as a compelling paradigm, promising to break down such monolithic system architectures into pools of shared, distributed resources. However, the transition to disaggregated resources introduces its own set of challenges, including the need for significant code refactoring, potential performance penalties, substantial new hardware investments, increased complexity in system maintenance, and security concerns. Amidst this landscape, cache coherent interconnects, like Intel’s Ultra Path Interconnect (UPI)/QuickPath Interconnect (QPI), AMD’s Infinity Fabric, and Compute Express Link (CXL), offer a promising solution for disaggregated resources. By facilitating efficient access to remote memory through cache coherence for minimal latency and overhead, these interconnects are poised to significantly enhance the feasibility of resource disaggregation. This special issue of IEEE Micro seeks articles on the cutting-edge developments in cache coherent interconnects and their role in enabling resource disaggregation across computing, memory, and storage. Topics include, but are not limited to:

    Coherent Interconnect Protocols and Models for Resource Disaggregation Systems.
    Software/Hardware Co-Designs for High-Performance Disaggregated Coherency Management.
    Processor/Accelerator Designs Oriented towards Management in Coherent Disaggregated Systems. 
    Application-Architecture Co-Designs, Exploiting Coherent Disaggregation Techniques.
    Reliability, Testability, and Debuggability of Coherent Disaggregation Systems.
    Applications Based on Coherent Interconnects and Disaggregated Systems.

Special Issue on Data-Centric Computing
提出日: 2025-02-27

With the proliferation of mobile and edge computing devices, data generation continues to grow at an exponential rate, reaching an estimated 181 zettabytes processed per year by 2025. In response, computing systems large and small need to process ever-increasing amounts of data quickly and efficiently, leading to the rise of data-centric computing. Data-centric computing covers a broad range of hardware and software co-design topics, spanning techniques that (1) reduce the amount data transmitted, (2) optimize data movement using knowledge of latency and bandwidth of the connections between compute and sources of data, (3) integrate specialized heterogeneous or non-von-Neumann components in data-processing systems, or (4) develop new methods to synthesize or summarize data in place or minimize the overhead of data accesses. A common thread emerging across data-centric computing techniques is the need for hardware/software co-design in compute, memory, storage, and interconnect to deliver sizable improvements in performance and energy efficiency that rely on both traditional and unconventional scaling techniques

This special issue of IEEE Micro solicits academic and industrial research on co-designed solutions that revisit traditional boundaries between compute, memory, storage, interconnect and the software to support new architectures and programming abstractions. The solutions that will meet the test of time will balance specificity with generality, classify general principles, and denote metrics to measure a solution’s benefits and highlight remaining challenges. These solutions will serve as a template for how to apply future innovations in hardware and software to emerging use cases requiring even more generated data.

Special Issue on AI for Hardware and Hardware for AI
提出日: 2025-04-25

For years, the computational landscape, stretching from data centers and supercomputers to simple home devices, has predominantly depended on general-purpose processors which were sustainable while Moore’s law guaranteed that chip transistor counts would double approximately every two years. Today, however, as the pace of Moore’s law decelerates, we have witnessed an increasing shift toward hardware accelerators, designed to efficiently utilize hardware resources by concentrating solely on implementing the specific demands of target applications. Hardware accelerators, primarily engineered for an array of AI applications, from computer vision to recommendation systems and natural language processing, have been gaining growing traction, with substantial industrial investments and increasing scholarly interest. While the shift toward hardware accelerators has proven their capabilities, they face new challenges with major AI growth. AI algorithms are not only scaling in size rapidly but also evolving at an accelerated rate. The scale and diversity in modern AI pose a substantial challenge in the design of hardware accelerators for them. As a result, this IEEE Micro Special Issue seeks articles not only related to the hardware accelerators for the next generation of AI but also to the exploration of how AI itself can facilitate the creation of cost-efficient, fast, and scalable hardware. This issue’s topics of interest include, but are not limited to:

    Scalable hardware accelerators for the next generation of large AI models 
    Deploying new technologies (e.g., in-memory computing, photonics, analog computing) for AI efficiency
