  摘要:
  Emerging data-intensive applications, such as graph analytics and data mining, exhibit tremendous datasets and irregular memory access patterns. Research has shown that these memory-bound applications are unable to effectively leverage the principles of data locality and regular memory accesses within traditional cache-based memory systems to mitigate the “memory-wall” issue. The expansion of data volume has simultaneously driven a transition from monolithic architectures towards systems integrated with discrete and distributed nodes in large-scale computing systems. As such, multi-layered software infrastructures have become essential to bridge the gap between heterogeneous commodity devices. However, operations across synthesized components with divergent interfaces inevitably lead to redundant software footprints and undesired latency. Therefore, a scalable and unified computing platform, capable of supporting efficient interactions between individual components, is desirable for large-scale data-intensive applications. 
  In our presentation, we will unveil the Extended Base Global Address Space, or xBGAS, a novel extension for the RISC-V instruction set architecture (ISA), designed for scalable and high-performance computing. The xBGAS extension revolutionizes the landscape by providing native ISA-level support for direct remote shared memory access, achieved through the mapping of remote objects into an extended system address space. Further, we will walk through the performance ramifications of xBGAS through an insightful examination of both software and hardware, employing a wide range of data-intensive workloads.
