Cache-Related Performance Analysis Using Rogue Wave Software’s ThreadSpotter

Abstract

Modern processors cannot deliver high performance without applying caching mechanisms. However, the cache-conscious programming requires from the developer quite a deep knowledge about the underlying processor’s hardware architecture and is thus very hard to be adopted by the software codes. The cache-aware application optimization is getting even more challenging for the parallel (multi-threaded) applications running in multi-processor and/or multi-core environments. We introduce the Rogue Wave Software’s ThreadSpotter performance analysis tool, which is designed to simplify the cache-aware application development by leveraging the unique performance optimization techniques. Following an original statistical approach, ThreadSpotter enables the in-depth application analysis on the wide range of hardware platforms.
