      CPU and System Topology

      Server Description

      A dedicated thirty-two core AMD EPYC compute instance designed for multi-threaded processing and balanced memory-to-CPU workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.c6a.8xlarge is a compute-optimized virtual server instance featuring 32 dedicated vCPUs and 32 physical cores on the x86_64 architecture. Powered by an AMD EPYC 7H12 processor running at 2.6 GHz, the server is equipped with 64.0 GB of RAM, yielding 2.0 GB of memory per core. It contains no local storage or GPU accelerators, and operates with an 8 Gbps baseline network bandwidth. Benchmark data reveals average multi-core CPU performance and average small-block cached memory bandwidth, though uncached large-block memory throughput is weaker. The dedicated CPU allocation makes this instance cost-efficient for compute-heavy, multi-threaded workloads. It is well-suited for static web serving, Redis operations, and parallel batch processing tasks.

      Workload Profiles

      1.03Score
      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.
