STAC Report: STAC-A2 Pack for oneAPI (Rev R) with 2 x Intel Xeon 6980P Processors, Micron MRDIMMs and Red Hat Enterprise Linux 9.5

First audit of MRDIMMs for STAC-A2

13 May 2025

STAC recently performed STAC-A2 Benchmark tests on a stack consisting of 2 x Intel Xeon 6980P Processors, Micron MRDIMMs and Red Hat Enterprise Linux 9.5

The STAC Public Report is now available here.

STAC-A2 is the technology benchmark standard for financial market risk analysis, evaluating the performance, scaling, quality, and resource efficiency of stacks capable of running a compute-intensive workload: Monte Carlo estimation of Heston-based Greeks for a path-dependent, multi-asset option with early exercise.

Compared to all publicly reported solutions to date, this solution based on 2x Intel® Xeon® 6980P Processors set a new performance record for the fastest cold time in the baseline problem size Greeks benchmark¹, improving the previous best time by 1.08x

Compared to a solution featuring 2 x Intel® Xeon® Platinum 8952+ Processors and the rev N of Intel STAC Pack (SUT ID INTC240321), this solution delivered:

• 2.13x the throughput²
• 9.89x / 1.56x the speed in cold / warm runs of the baseline problem size³
• 1.98x / 2.09x the speed in cold / warm runs of the large problem size⁴
• 1.28x the energy efficiency⁵

Compared to a solution using 4x NVIDIA A100 GPUs, 2x AMD EPYC 7713, and rev G of the NVIDIA STAC Pack (SUT ID NVDA221007), this solution delivered:

• 1.52x / 1.22x the speed in cold / warm runs of the large problem size⁴
• 3.92x / 85% the speed in cold / warm runs of the baseline problem size³
• 5.10x lower idle power⁶

Intel also contributed a STAC-A2 Vault report featuring 2 x Intel® Xeon® 6767P processors in a QuantaGrid D55Q-2U system with 512 GiB of memory and running Red Hat Enterprise Linux 9.5 (Plow).

Premium subscribers have access to the Vault report as well as the code used in each project and the detailed configuration information for each solution. To learn about subscription options, please contact us.
