Think System SR665 V3 Sets 4 World Records with New SPE Chpc 2021 Small Benchmark Result Performance Benchmark Result
The Lenovo Think System SR665 V3 has set four performance world records with new 2-socket results of the Speech 2021 Small benchmark.
These new benchmark results, published in new SPEC reports on November 10, 2022, demonstrate that the Think System SR665 V3 continues Lenovo’s leadership with outstanding performance for the server industry.
The SR665 V3, using pure MPI as node-level parallelization model, has achieved the following scores:

SPEChpc_2021_sml_base = 1.23
SPEChpc_2021_sml_peak = 1.23

The SR665 V3, using MPI+OpenMP as node-level parallelization model, has achieved the following scores:

SPEChpc_2021_sml_base = 1.45
SPEChpc_2021_sml_peak = 1.45

The SPE Chpc 2021 Benchmark suite is the industry standard to evaluate hardware-based accelerator devices and the performance of parallel computing workloads. To support heterogeneity system architecture, the Speech 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 Speech 2021, hence the performance improvement.
The Think System SR665 V3 server was configured as follows:

2x AMD EPYC 9654 processors (96 cores, 2.40 GHz)
768 GB memory (24x 32GB RDIMMs at 4800MHz)
480 GB 2.5-inch SSD
Red Hat Enterprise Linux 8.6

The results are current as of November 10, 2022.

About the Think System SR665 V3

The Think System SR665 V3 is a 2S 2U rack server built with the performance and flexibility to manage a complex set of workloads like data management, analytics, virtualization, cloud, and AI. The 192 cores of the dual 4th Gen AMD EPYC™ processors with up to 160 PCIe lanes and up to 6TB of the latest DDR5 memory, maximize the performance of this 2U server.
The SR665 V3 is designed to support today’s infrastructure and easily scale to prepare for next gen workloads. Multiple drive options from SAS/SATA, NVMe, and EDSFF with hot-swap capabilities and XClarity system management software enable changes to be made quickly with ease. The versatile design doesn’t stop at storage, the SR665 V3 includes support for multiple options for GPU and PCIe to satisfy graphics, speed, and budget requirements.

About SPEChpc 2021

High Performance Computing (HPC) systems are getting built with an increased level of heterogeneity. The numerous types of accelerators bring in tremendous extra computing power, while at the same time introduce big challenges in performance evaluation and characterization. More complications are added to the problem when multiple parallel and accelerator programming models have been developed with each only supporting a subset of the computing devices.
The SPEChpc 2021 Benchmark Suite address these challenges by providing a set of application benchmark suites using a comprehensive measure of real-world performance for the state-of-the-art HPC systems.
They offer well-selected science and engineering codes that are representative of HPC workloads and are portable across CPU and accelerators, along with certain fair comparative performance metrics.
SPEChpc 2021 focuses on compute intensive parallel performance across one or more nodes, which means these benchmarks emphasize the performance of the following components:

Processors & GPUs – The CPU chips and optionally, an acceleration device such as a GPU
Memory – The memory hierarchy, including caches and main memory
Interconnects – The communication between nodes of a cluster
Compilers – C, C++, and Fortran compilers, including optimizers
MPI – The MPI implementation.

The SPEChpc 2021 benchmark suite is broken out into four workloads, Tiny, Small, Medium and Large:

SPEChpc2021 Tiny workloads use up to 60 GB of memory and are intended for use on a single node using between 1 and 256 ranks.
SPEChpc2021 Small workloads use up to 480 GB of memory and are intended for use on one or more nodes using between 64 and 1024 ranks
SPEChpc2021 Medium workloads use up to 4 TB of memory and are intended for use on a mid-size cluster using between 256 and 4096 ranks
SPEChpc2021 Large workloads use up to 14.5 TB of memory and are intended for use on a larger clusters using between 2048 and 32,768 ranks
