Abstract
Due to emerging workloads that require high memory bandwidth, Processing-in-Memory (PIM) has gained significant attention and led several industrial PIM products to be introduced which are integrated with conventional computing systems. This letter characterizes the data transfer overheads between conventional DRAM address space and PIM address space within a PIM-integrated system using the commercialized PIM device made by UPMEM. Our findings highlight the need for optimization in PIM-integrated systems to address these overheads, offering critical insights for future PIM technologies.
期刊介绍：
IEEE Computer Architecture Letters is a rigorously peer-reviewed forum for publishing early, high-impact results in the areas of uni- and multiprocessor computer systems, computer architecture, microarchitecture, workload characterization, performance evaluation and simulation techniques, and power-aware computing. Submissions are welcomed on any topic in computer architecture, especially but not limited to: microprocessor and multiprocessor systems, microarchitecture and ILP processors, workload characterization, performance evaluation and simulation techniques, compiler-hardware and operating system-hardware interactions, interconnect architectures, memory and cache systems, power and thermal issues at the architecture level, I/O architectures and techniques, independent validation of previously published results, analysis of unsuccessful techniques, domain-specific processor architectures (e.g., embedded, graphics, network, etc.), real-time and high-availability architectures, reconfigurable systems.
