      CPU and System Topology

      Server Description

      A dedicated 32-core x86_64 compute platform with a 1:2 memory-to-core ratio, optimized for parallelized multi-threaded workloads.

      Compute OptimizedGeneral Purpose

      Alibaba Cloud ecs.u1-c1m2.8xlarge is an x86_64 compute-oriented server featuring 32 dedicated Intel Xeon physical cores and vCPUs running at 2.5 GHz. Equipped with 64.0 GB of RAM, it provides a 1:2 vCPU-to-RAM ratio, with no local storage or GPU accelerators. Network performance is anchored by a 10 Gbps baseline bandwidth. Performance benchmarks reveal a contrast between weak single-core execution and average multi-core capabilities, as demonstrated in stress-ng and Geekbench multi-threaded tests. Memory bandwidth and database operations also align with mid-range performance tiers. This hardware profile is qualitatively cost-efficient for parallelized workloads that benefit from high core counts but do not require extensive memory per core. It is suited for multi-threaded software compilation, static web serving, and parallel data processing.

      Workload Profiles

      1.31Score
      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.
