• SPEChpc_2021_tny_base = 79.9
• SPEChpc_2021_tny_peak = 80.4

SR675 V3, using OpenACC as node-level parallelization model, has achieved the best 1 node, Base and Peak ACC score as follows:

• SPEChpc_2021_tny_base = 79.9
• SPEChpc_2021_tny_peak = 80.4

SR675 V3, using OpenACC as node-level parallelization model, has achieved the best 1 node, 2 socket, 7 GPU base and peak score as follows:

• SPEChpc_2021_sml_base = 11
• SPEChpc_2021_sml_peak = 11.1

The SPEChpc 2021 Benchmark suite is the industry standard to evaluate hardware-based accelerator devices and the performance of parallel computing workloads.

In order to support heterogeneity system architecture, the SPEChpc 2021 benchmark supports multiple programming models:

• Pure MPI
• MPI+OpenMP
• MPI+OpenACC
• MPI+OpenMP with target offload

By properly configuring the CPU based system according to NUMA architecture, the MPI+OpenMP can reduce communication needs and memory consumption in some sub-benchmark of SPEChpc 2021, hence the performance improvement.

ThinkSystem SR675 V3 server was configured as follows:

• 2x AMD EPYC 9654 processors (96 cores, 2.40GHz)
• 768GB memory (24x32GB RDIMMs at 4,800MHz)
• 8xNVIDIA H100 PCIe 80GB GPUs
• Red Hat Enterprise Linux 8.6

The results are current as of November 1, 2023.
