The Lenovo ThinkSystem SR655 V3 server has set two new 1-socket performance world records with the SPECompG_base2012 and SPECompG_peak2012 metrics of the SPEC OMP2012 Benchmark. The SPEComp Benchmark suite is the industry standard to evaluate performance using applications based on the OpenMP 3.1 standard for shared-memory parallel processing.
This document summarizes the the SPECompG benchmark result for the ThinkSystem SR655 V3 that was published on July 1, 2023. The document lists the result, summarizes the major components of the configuration under test, and provides the link to the relevant benchmark organization’s web site for details about the result.
The Lenovo ThinkSystem SR655 V3 server has set two new 1-socket performance world records with the SPECompG_base2012 and SPECompG_peak2012 metrics of the SPEC OMP2012 Benchmark.
This new benchmark result, published in a new SPEC report on July 1, 2023, demonstrate that the ThinkSystem SR655 V3 continues Lenovo’s leadership with outstanding performance for the server industry.
The SPEC OMP2012 Benchmark suite is the industry standard to evaluate performance using applications based on the OpenMP 3.1 standard for shared-memory parallel processing and includes 14 scientific and engineering application codes, covering everything from computational fluid dynamics (CFD) to molecular modeling to image manipulation.
The ThinkSystem SR655 V3 has achieved the following scores:
- SPECompG_base2012 = 52.7
- SPECompG_peak2012 = 53.4
This result is the best 1-socket performance in the industry.
The SR655 V3 was configured as follows for the benchmark audit:
- 1x AMD EPYC 9754 ("Bergamo") processor (128 cores, 2.25GHz)
- 1TB DDR5 memory (16x 64GB RDIMMs, 4800MHz)
- ThinkSystem 1 TB SATA HDD
- SUSE Enterprise for High-Performance Computing 15 SP4
Results referenced are current as of July 1, 2023.
