In this video from SC14, Patrick Wohlschlegel from Allinea Software demonstrates how the company’s Performance Reports took has been integrated into HP’s cluster management system for system administrators.
“I have a few people helping out and tuning user applications, but we cannot serve all of our 500 users– we don’t have enough people. But if I have such a tool like Allinea Performance Reports, we tell them to try that out first and then if they have a problem, then they can do the first assessment themselves. Then we can use this tool to find the hard cases when my guys need to get involved. This is great.”
“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.”
