Abstract
This paper provides a technical overview of the deployment and optimization of Cornelis Networks CN5000 Omni-Path® SuperNIC adapters and high-performance fabric switches within a Lenovo ThinkSystem–based HPC cluster. The guidance is based on a real-world implementation in the Lenovo HPC Benchmarking Centre using ThinkSystem SC750 V4 servers powered by Intel® Xeon® 6 processors. The document outlines key considerations for hardware provisioning, software deployment, and fabric validation, including integration with Lenovo Confluent management software for scalable cluster configuration and lifecycle management. It also presents performance validation using industry-standard benchmarks, demonstrating low-latency communication and near line-rate bandwidth across the fabric.
In addition, the paper highlights practical tuning techniques—including MPI configuration, context sharing, bulk transfer services, and SDMA optimization—to help ensure that cluster performance reflects the full capabilities of the underlying hardware.
The methodologies, results, and best practices presented are intended to help HPC architects, system administrators, and Lenovo solution teams deploy CN5000-based clusters efficiently and achieve consistent, high-performance outcomes in production environments.
