Ansys Fluent Performance Analysis with Cornelis Omni-Path

This white paper presents an analysis of the performance of Ansys Fluent when utilized with Cornelis Omni-Path networking fabric. It outlines how users can achieve equal performance at a significantly lower cost, potentially up to 40% less than competing solutions. The paper details the capabilities of the Cornelis Networks Omni-Path 100Gbps high-performance networking fabric, which is designed for high-performance computing, artificial intelligence, and data analytics. It documents the results of benchmark tests comparing Ansys Fluent performance over Cornelis Omni-Path and NVIDIA InfiniBand HDR, indicating that users can achieve up to 1.55 times higher job throughput per fabric cost with Omni-Path. The paper also provides specific system configurations used during testing and discusses the advantages of the new Cornelis OPX provider for libfabric, which enhances performance on existing hardware. The findings suggest that deploying Cornelis Omni-Path can lead to both operational and financial benefits for users.
