      Server Description

      A dedicated 96-core compute platform with high-speed networking designed for parallel processing and intensive engineering simulations.

      Compute Optimized

      Amazon Web Services hpc6a.48xlarge is a compute-optimized server featuring 96 dedicated physical AMD EPYC 7R13 cores running at 3.6 GHz on the Nitro hypervisor. It is equipped with 384.0 GB of DDR4 memory and a 100 Gbps baseline network interface, but lacks local storage and GPU accelerators. Benchmarks show top-tier multi-core CPU performance, ranking in the top 10% for Passmark CPU tests, multi-threaded decompression, and cached memory bandwidth. However, single-core performance and LLM text generation speeds are average to weak. This hardware profile delivers high compute density for parallel workloads, making it suitable for software compilation, ray tracing, and large-scale engineering simulations, while being less optimal for storage-heavy or GPU-dependent tasks.

      Workload Profiles

      4.38Score
      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.
