Slidecast: Energy-efficient Computation

“A crazy idea was born at ISC14 while answering questions about the new energy metrics in Allinea Performance Reports and Allinea MAP – could the information in these reports show us an easy way to increase energy efficiency without having to change the program? The idea was to use CPU frequency scaling to run memory-bound jobs at a lower clock frequency. In Lazy Energy Efficiency Challenge One, I found that on a synthetic benchmark I could increase the iterations per watt by 19% on a memory-bound code.”

Demo: Allinea Performance Reports Finds Bottlenecks Fast

“In this video, Mark O’Connor from Allinea demonstrates how the company’s Performance Reports software generates easy-to-understand pages that characterize the performance of HPC application runs.”

Allinea Performance Reports Improves HPC Utilization at Cardiff University

A new tool called Allinea Performance Reports is allowing Cardiff University researchers to see clearly what is happening within their HPC system.

Demo: Allinea Performance Reports for Comparative Debugging

In this video from SC13, Mark O’Connor from Allinea Software describes how the company’s new Performance Report Tools provides a scalable and effective way to characterize and understand the performance of HPC application runs, without needing to instrument or recompile.
