      CPU and System Topology

      Server Description

      A 32-vCPU compute-optimized server featuring 64 GB RAM and dedicated Intel Xeon processing for scalable parallel workloads.

      Compute Optimized

      Alibaba Cloud ecs.c6.8xlarge is a compute-optimized server instance powered by a 16-core, 32-vCPU Intel Xeon 8269CY processor clocked at 2.5 GHz on an x86_64 architecture. Configured with 64.0 GB of RAM (2.0 GB per vCPU) and a 10 Gbps network connection, it contains no local disk storage or hardware GPU accelerators. Benchmark evaluations position its multi-core processing, memory throughput, and parallel execution capabilities in the average range, highlighted by multi-threaded bzip3 decompression at 127.99 GB/sec and 26.78 million Redis SET operations per second. While single-thread processing exhibits lower relative performance, its dedicated 32-vCPU resource layout provides solid multi-core density. Without local storage, it relies on network storage, making it cost-efficient for CPU-intensive parallel workloads such as code compilation, CI/CD automation, distributed compute tasks, and high-concurrency web serving.

      Workload Profiles

      1.3Score
      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.
