SPEC, the organization responsible for publishing benchmark results, has taken a decisive step to ensure fairness and accurate performance evaluations. In response to a controversial optimization technique used in a specific version of the Intel compiler, SPEC has invalidated over 2,600 benchmark results achieved by Intel CPUs running this compiler.
The disqualification primarily affects machines equipped with 4th Gen Xeon Sapphire Rapids CPUs, commonly found in high-end servers, data centers, and workstations. These benchmark results were obtained using SPEC CPU 2017, a standardized benchmark that assesses the performance of various workloads on different computer systems.
While hardware plays a crucial role in benchmark results, software-side optimization, including compiler usage, can significantly influence the outcomes. However, the contentious optimization technique in question focused solely on two specific benchmarks within the SPEC CPU 2017 suite: 523.xalancbmk_r and 623.xalancbmk_s.
This optimization technique, as reported by Phoronix, could potentially enhance the SPECint performance by 9%. It is important to note that this increase is limited to the targeted benchmarks and does not extend to real-world applications.
Benchmark-specific optimization controversies have arisen in the past, involving companies like Nvidia and AMD in relation to GPU performance and driver-side settings. SPEC, with its action to disqualify the SPEC CPU 2017 results, aims to address this issue and emphasize the significance of comprehensive and reliable benchmarking.
The organization’s goal is to create an environment that accurately reflects the actual performance capabilities of computer systems. By invalidating the results achieved using the specific version of the Intel compiler, SPEC reinforces the values of fairness, objectivity, and reliable benchmarking practices.
In conclusion, SPEC’s decision to invalidate these benchmark results reestablishes the importance of maintaining integrity in performance evaluations. Through this action, SPEC aims to promote a benchmarking environment that faithfully represents the real-world performance of computer systems while upholding the principles of fairness and reliability.
