      CPU and System Topology

      Server Description

      A compute-optimized virtual server featuring thirty-two dedicated vCPUs and a highly parallelized architecture for compute-intensive, low-memory workloads.

      Compute Optimized

      Alibaba Cloud ecs.ic5.8xlarge is a compute-optimized instance featuring 32 dedicated vCPUs and 32.0 GB of memory, powered by an Intel Xeon 8163 processor at 2.5 GHz. Built on the x86_64 architecture, it includes 16 physical cores, a 35 MB L3 cache, and support for AVX-512 instructions. The instance lacks local storage and GPUs, relying on a 10 Gbps baseline network interface. Performance benchmarks reveal weak single-core capabilities but average multi-core execution, memory bandwidth, and database operations. Given its low memory-to-vCPU ratio of 1.0 GB per core, this server represents a resource-dense option for parallelized, compute-bound workloads. It is best suited for multi-threaded applications, software compilation, static web serving, and Redis deployments.

      Workload Profiles

      1.1Score
      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.
