====== OmniCompute 8100 (OC8100) AI Server Data Sheet ======

The Alcatel-Lucent OmniCompute 8100 (OC8100) AI Server is a high-performance, scalable, GPU-based server ideally suitable for AI/ML (Artificial Intelligence/Machine Learning) and HPC (High-Performance Computing) applications. The server is ideal for training large language models, automation, object classification, and recognition use cases. The system is designed with eight AMD Instinct MI325X GPUs and dual AMD EPYC 9005/Turin series processors. The AMD MI325X GPU integrates 256 GB of HBM3 memory each.

Each MI325X offers a 16-lane PCIe Gen5 host interface and seven AMD Infinity Fabric(tm) links for full connectivity between eight GPUs. AMD Infinity Fabric technology delivers excellent I/O efficiency, scaling and communication within and between industry-standard accelerator module (OAM) device packages.

===== Key Features and Benefits =====
  * Featuring eight AMD Instinct(tm) MI325X GPUs based on CDNA(tm) 3 architecture
  * Dual 5th Gen AMD EYPC processors with advanced data center performance and efficiency
  * 7 Infinity Fabric(tm) links with 128 GB/s for full connectivity between 8 GPUs in a ring (scale-up)
  * 16 PCIe Gen5 with 128GB/s bandwidth for scale-out network
  * Up to 1.3X AI performance and up to 2.4X HPC performance vs. competitive accelerators
  * AMD ROCm(tm) software optimized for generative AI and HPC applications, easy for migrating existing code
