Intel Inspector XE 2011 automatically finds memory errors, deadlocks and other conditions that could lead to deadlocks, data races, thread . Some specific issues associated with debugging multithreaded applications will be discussed in this article.
When confronted with nested loops, the granularity of the computations that are assigned to threads will directly affect performance. Loop transformations such as splitting and merging nested loops can make parallelization easier and more productive.

This article discusses how coding and optimization on-the-fly are opposed and how performance experts approach performance improvement. It explains how they systematically prepare their code for optimization and how the optimization process is done.
One key to attaining good parallel performance is choosing the right granularity for the application. Granularity is the amount of real work in the parallel task. If granularity is too fine, then performance can suffer from communication overhead.
