AMD Instinct™ High Performance Computing and Tuning Guide¶
HPC workloads have unique requirements. The default hardware and BIOS configurations for OEM platforms may not provide optimal performance for HPC workloads. To help enable optimal HPC settings on a per-platform and workload level, this guide calls out:
BIOS settings that can impact performance
hardware configuration best practices
supported versions of operating systems
workload-specific recommendations for optimal BIOS and operating system settings
There is also a discussion on the AMD Instinct™ software development environment, including information on how to install and run the DGEMM and STREAM benchmarks as well as GROMACS. This guidance provides a good starting point but is not exhaustively tested across all compilers.
Prerequisites to understanding this document and to perform tuning of HPC applications include:
Experience configuring servers
Administrative access to the Server’s Management Interface (BMC)
Administrative access to the operating system
Familiarity with OEMs Server’s Management Interface (BMC) is strongly recommended
Familiarity with the OS specific tools for configuration, monitoring and troubleshooting is strongly recommended
This document provides guidance on tuning systems with AMD Instinct™ accelerators for High Performance Computing (HPC) workloads. This document is not an all-inclusive guide, and some items referred to may have similar, but different, names in various OEM systems (for example, OEM-specific BIOS settings). This document also provides suggestions on items that should be the initial focus of additional, application-specific tuning.
This document is based on the AMD EPYC™ 7002 series processor family (former codename “Rome”). One can expect very similar results for the AMD EYPC™ 7003 series processor family (former codename “Milan”). Specific differences in the configuration options or performance obtained will be explicitly called out through the document where needed.
While this guide is a good starting point, developers are encouraged to perform their own performance testing for additional tuning.
