1.4 Common Considerations
Across all tiers, the following considerations apply:
- **Chipset:** The Intel C621A chipset is commonly used for dual-socket Xeon Scalable platforms and provides robust I/O capabilities. Chipset Architecture details the functionality of this chipset.
- **BIOS:** Ensure the motherboard BIOS is updated to the latest version for optimal AVX support and stability.
- **Operating System:** A 64-bit operating system (e.g., Linux distributions like CentOS, Ubuntu Server, or Windows Server) is required to fully utilize AVX instructions.
- **Virtualization:** If virtualization is planned, ensure the hypervisor (e.g., VMware ESXi, KVM) supports AVX passthrough to virtual machines. Virtualization Technologies provides a detailed overview.
2. Performance Characteristics
AVX instruction sets accelerate workloads that can be parallelized, particularly those involving Single Instruction, Multiple Data (SIMD) operations. The performance gains depend heavily on the specific application and how well it is optimized for AVX.
2.1 Benchmark Results
The following table summarizes benchmark results for the Silver Tier configuration, comparing performance with and without AVX optimization. Benchmarks were conducted using SPEC CPU 2017 and Linpack.
