In this video from the 2014 HPC Advisory Council Spain Conference, Pak Lui from Mellanox presents: Cluster Optimizations – How to Achieve Optimal Performance.
To achieve good scalability performance on the HPC scientific applications typically involves good understanding of the workload though performing profile analysis, and comparing behaviors of using different hardware which pinpoint bottlenecks in different areas of the HPC cluster. In this session, a selection of HPC applications will be shown to demonstrate various methods of profiling and analysis to determine the bottleneck, and the effectiveness of the tuning to improve on the application performance.”
