Addressing Application Bottlenecks: Microarchitecture
Alexander Supalov, Andrey Semin, Michael Klemm, Christopher Dahnken · Apress eBooks · 2014
Microarchitectural performance tuning is one of the most difficult parts of the performance tuning process. In contrast to other tuning activities, it is not immediately clear what the bottlenecks are. Usually, discovering this requires study of processor manuals, which provide the details of the execution flow. Furthermore, a certain understanding of assembly language is needed to reflect the findings back onto the original source code. Each processor model will also have its own microarchitectural characteristics that have to be considered when writing efficient software. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
