SPEC, the leading organization in publishing benchmark results, has taken a significant step to uphold fairness and accuracy in performance evaluations. To address a controversial optimization technique employed in a specific version of the Intel compiler, SPEC has invalidated more than 2,600 benchmark results achieved by Intel CPUs running this compiler.
The disqualification primarily impacts systems equipped with 4th Gen Xeon Sapphire Rapids CPUs, commonly found in high-end servers, data centers, and workstations. These results were obtained using SPEC CPU 2017, a standardized benchmark that assesses the performance of various workloads on different computer systems.
While hardware is crucial in determining benchmark results, software-side optimization, including compiler usage, can greatly influence outcomes. In this case, the contentious optimization technique exclusively targeted two benchmarks within the SPEC CPU 2017 suite: 523.xalancbmk_r and 623.xalancbmk_s.
The reported optimization technique had the potential to increase SPECint performance by 9%. However, it’s important to note that this improvement was limited to the specific benchmarks and did not extend to real-world applications.
Similar optimization controversies have emerged in the past, involving companies like Nvidia and AMD, where GPU performance and driver-side settings were called into question. By disqualifying the SPEC CPU 2017 results, SPEC aims to tackle these issues while emphasizing the significance of comprehensive and reliable benchmarking.
SPEC’s objective is to establish an environment that accurately represents the actual performance capabilities of computer systems. Through the invalidation of results achieved using the specific version of the Intel compiler, SPEC reinforces the values of fairness, objectivity, and reliable benchmarking practices.
SPEC’s decision reaffirms the importance of maintaining integrity in performance evaluations and highlights the organization’s commitment to promoting a benchmarking environment that reflects real-world system performance while upholding principles of fairness and reliability.
