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.
