• Run Basic Hotspots analysis type to understand application flow and identify sections of code that get a lot of execution time (hotspots).

• Run Concurrency analysis to estimate parallelization in your code and understand how effectively your application uses available cores.

• Run Locks and Waits analysis to identify synchronization objects preventing effective utilization of processor resources.

• Use the algorithm Advanced Hotspots analysis to extend Basic Hotspots analysis by collecting call stacks, context switches and analyze CPI (Cycles Per Instructions) metric.

• Run General Exploration analysis to triage hardware issues in your application. This type collects a complete list of events for analyzing a typical client application.

• Narrow down your hardware analysis by focusing on specific hardware issues, such as ineffective memory accesses, low bandwidth, and so on. VTune Amplifier analyzes your code, identifies issues and provides recommendations.

• Double click a hotspot function to drill down to the source code and analyze performance per source line or assembler instruction. By default, the hottest line is highlighted.

• For help on an assembly instruction, right-click the instruction in the Assembly pane and select Instruction Reference from the context menu.

• Run CPU/GPU Concurrency analysis to identify code regions where your application is CPU or GPU bound.

• For GPU-bound applications running on Intel HD Graphics, collect GPU hardware events to estimate how effectively the Processor Graphics are used.

• Analyze hot Intel® Media SDK programs and OpenCL™ kernels running on a GPU. For OpenCL application analysis, use the Architecture Diagram to explore GPU hardware metrics per GPU architecture blocks.

• Select Custom Analysis branch in the analysis tree to create your own analysis configurations using any of the available VTune Amplifier data collectors.

• Run your own custom collector from the VTune Amplifier to get the aggregated performance data, from your custom collection and VTune Amplifier analysis, in the same result.

• Import performance data collected by your own or third-party collector into the VTune Amplifier result collected in parallel with your external collection. Use the Import from CSV button to integrate the external data to the *.amplxe result.

Use the Intel Energy Profiler to investigate high energy consumption on a platform with its summaries of CPU and GPU state residency, CPU and GPU processor frequency use, and correlated timelines of metrics that reflect platform energy use, such as thermals and bandwidth. The CPU sleep state timeline is annotated with wakeup reasons.
