Long tail latency and server debug

The rise of the heterogeneous multicore processor has enabled a massive increase in the ability of data centers to deliver advanced services to billions of users worldwide. But the complexity that is now possible has made the optimization of these services difficult to achieve, with overall performance often determined by a long tail of latency effects.

This White paper describes the impact of long tail latency and server debug and details software strategies for latency avoidance and performance debug.
