HK 实测背景 / HK Validation Context

hkghpcn1 上的 EPYC 9475F 已完成 LS-DYNA MPP、Intel MPI 与 ANSYS License 链路验证：4 MPI ranks、19,862 cycles、Elapsed 4 seconds、Normal termination。

The existing EPYC 9475F node completed an end-to-end LS-DYNA MPP, Intel MPI, and ANSYS licensing validation.

限制：该 airbag 模型运行时间仅约 4 秒，初始化时间占比高，适合功能验证，不适合作为硬件性能结论。
Limitation: The four-second airbag case is suitable for functional validation, not final CPU performance ranking.

验收测试 / Benchmark Acceptance

  1. 使用同一个真实、运行时间足够长的 LS-DYNA 模型。
    Use the same representative LS-DYNA model with a sufficiently long runtime.
  2. 固定 LS-DYNA executable、MPI、精度、存储路径和 NUMA 配置。
    Fix executable, MPI, precision, storage path, and NUMA policy.
  3. 测试 8/16/24/32/48 核；64 核 CPU 增加 64 核。
    Test 8/16/24/32/48 cores; add 64 cores for 64-core CPUs.
  4. 记录 Runtime、Cycles、Core-Minutes、Jobs/day、功耗和 License 消耗。
    Record runtime, cycles, core-minutes, jobs/day, power, and license consumption.

采购结论 / Procurement Decision

中文：如果只统一采购一种 CPU，推荐 AMD EPYC 9475F。如果建立两级计算池，建议 9475F 作为主力标准节点，9575F 作为高性能和高并发节点。9375F 更适合预算敏感并且作业通常不超过 32 核的场景。

English: If one CPU must be standardized across the cluster, choose AMD EPYC 9475F. For a two-tier compute pool, deploy 9475F as the standard node and 9575F as the high-performance and high-concurrency node. EPYC 9375F is best suited to budget-sensitive workloads that typically remain at or below 32 cores.
