A Look at VTune. This advanced profiler increases application performance on modern hardware. Intel offers several complementary tools for analyzing, tuning, and optimizing application performance and reliability. However, if the gaps between busy intervals are big and the CPU is busy during these gaps, your application is most likely CPU-bound. Debug difficult intermittent races and deadlocks without special recompiles. But such obvious situations are often rare. VTune Amplifier performance profiler is a commercial application for software performance analysis of 32 and bit x86 based machines.

Shoot yourself in the foot when handling input data The linking concept of today’s article differs from usual. While executing the application, the utility measures time spent in modules, functions, code lines, and samples processor events those related to branch prediction, efficiency of micro-op fusion, partial outages associated with a particular module or function.
An application may be mistakenly considered GPU-bound when GPU engine usage is serialized for example, intel vtune amplifier xe GPU engines responsible for video processing and for rendering are loaded in turns.
The linking concept of today’s article differs from usual.
If you’re a student or classroom educator, you may intel vtune amplifier xe to receive a free full-featured suite. Try It Now Sample a complete suite for 30 days. Check your code with PVS-Studio. Choose the Best Option Choose a suite of development tools that best fits your needs.
Sort, filter, and visualize data from the GUI or automate with the command-line interface. However, we should not forget about optimization which, despite the common belief, has always been highly important too.
A paid intel vtune amplifier xe allows you to connect with Intel’s engineers through our Online Service Center. The tool can detect and locate performance issues through the following techniques: The tool can be also used to analyze thread and storage performance. Fine tuning can provide significant gains, especially if your game is CPU-bound.
Intel VTune Performance Analyzer allows the user to collect data about inside events of Intel processors, analyze them and find the most loaded code fragments called hotspots. You can also use them to address challenges where wait is a common cause of slow performance in parallel programs.
For more complete information about compiler optimizations, see our Optimization Notice. Buy the suite through a number of resellers or directly from the online store.
The timeline view helps you maximize software performance by letting you easily monitor and spot amplkfier contention, load imbalance, and inadvertent serialization.

For complete information, see the Release Notes. You can use the powerful VTune analysis tools to sort, filter, amlpifier visualize results on the timeline and on your source.
In Figure 10, the yellow lines depict transitions, where a high density of transitions may indicate lock contention and poor parallel performance. Single Thread Optimize single-threaded performance.
This article contains content that is written like an advertisement. The profiler result consists of details such as time spent in each sub routine which can be drilled down to the instruction level. I was able to make code run twenty times faster than our prototype version while handling five times the data load.
