Choose a suite of development tools that best fits your needs. ZeroMemory exploded, sizeof exploded ; You ze use the powerful VTune analysis tools to sort, filter, and visualize results on the timeline and on your source.
Items in italics are no longer maintained or have planned end-of-life dates. The time taken by the instructions are indicative of any stalls in the pipeline during instruction execution. You can download the utility here: In Figure 10, the yellow lines depict transitions, where a high density of transitions may indicate lock contention and poor parallel performance.

Retrieved from ” https: Tools for Performance Analysis 3. VTune Amplifier performance profiler is a commercial application for software performance analysis of 32 and bit x86 based machines. It also provides features for call graph profiling, gathering time characteristics of calls and intel vtune amplifier xe fragments that can be parallelized with the highest efficiency by using available processor cores to the full extent. If the Timeline pane in the Graphics window shows that the GPU is intel vtune amplifier xe most of the time with small, idle gaps between busy intervals, and a GPU software queue that rarely decreases to zero, your application is GPU-bound.
This article relies too much on references to primary sources. The tool employs the Sampling technology to evaluate performance issues caused by the most loaded functions. On the New year’s eve, a PVS-Studio team decided to make a nice gift for all contributors of open-source Find bottlenecks and achieve high performance for parallel cluster applications.
