Abstract:

The performance analysis gap is widening as processor complexity keeps climbing and developers are becoming more naïve than ever. Seemingly suitable programs can run correctly, but may suffer from hidden hardware bottlenecks that can severely hinder performance. Performance Monitoring Unit (PMU) events can provide programmers with unique and powerful insights into performance problems in their programs, but interpreting these events has been a significant challenge. While the conventional performance tuning tools can measure and visualize hardware events, they lack automatic identification of dominant resource bottlenecks and significant manual effort is required from experts to interpret the hardware events. 

ARGH!

IDK if I can make it.  I really ought to, but,,,
