    CPU and System Topology

    Server Description

    A GPU-accelerated virtual server featuring dedicated Intel Xeon processors and an NVIDIA A10 GPU for efficient AI inference and parallel processing.

    GPU AcceleratedGeneral Purpose

    Alibaba Cloud ecs.gn7i-c48g1.12xlarge is a GPU-accelerated instance featuring 48 vCPUs and 24 physical cores powered by an Intel Xeon 8369B processor running at 2.9 GHz. It is configured with 310.0 GB of system memory and a single NVIDIA Ampere A10 GPU with 24 GB of VRAM. The instance does not include local storage and provides a baseline network bandwidth of 16 Gbps. In benchmark testing, the server demonstrates top-tier performance in LLM inference for small and medium models, alongside strong capabilities in multi-threaded decompression and image processing. Lacking local storage, this instance is best suited for workloads such as AI inference, image processing, and GPU-accelerated compute tasks that rely on network-attached storage.

    Workload Profiles

    2.2Score
    Precomputed compound score for Cache Intensive workloads. A weighted average (geometric mean) of benchmark scores compared to their medians: score = ∏ (x_i / m_i)^(w_i / Σw). The score of 1.0 represents a synthetic baseline server with the median performance of each component benchmark; 0.5 means roughly half the performance; and 2.0 means twice the performance of that reference profile. Component weights: 50% Redis RPS (pipeline=1, SET), 20% Redis RPS (pipeline=16, SET), 10% PassMark Memory Mark (composite), 10% Memory bandwidth (read, 16 MB ~ L3), 10% PassMark single-thread CPU. Rationale for component selection: In-memory key-value store workload, mixing direct Redis performance metrics with memory speed and latency benchmarks, and single-core CPU performance profiles.
