Window: Summary - Memory Consumption

Use the
window as your starting point of the Memory Consumption analysis with the
Intel® VTune™
and identify top memory-consuming functions and memory allocation sizes. To access this window, select the
Memory Consumption
viewpoint and click the
sub-tab in the result tab.
Depending on the analysis type, the
window provides the following application-level statistics in the
Memory Consumption
Click the
Copy to Clipboard
button to copy the content of the selected summary section to the clipboard.

Analysis Metrics

The first section displays the summary statistics on the overall application execution:
All metric names are hyperlinks. Clicking such a hyperlink opens the
window and sorts the data in the grid by the selected metric.

Top Memory-Consuming Objects

This section displays a list of top memory-consuming functions. For example, the
function has the highest Memory Consumption metric value and could be a candidate for optimization:

Collection and Platform Info

This section provides the following data:
Application Command Line
Path to the target application.
Operating System
Operating system used for the collection.
Computer Name
Name of the computer used for the collection.
Result Size
Size of the result collected by the
Collection start time
Start time (in UTC format) of the external collection . Explore the
pane to track the performance statistics provided by the custom collector over time.
Collection stop time
Stop time (in UTC format) of the external collection. Explore the
pane to track the performance statistics provided by the custom collector over time.
Collector type
Type of the data collector used for the analysis. The following types are possible:
CPU Information
Name of the processor used for the collection.
Frequency of the processor used for the collection.
Logical CPU Count
Logical CPU count for the machine used for the collection.
Physical Core Count
Number of physical cores on the system.
User Name
User launching the data collection. This field is available if you enabled the per-user event-based sampling collection mode during the product installation.
GPU Information
Name of the Graphics installed on the system.
GPU vendor.
Version of the graphics driver installed on the system.
Microprocessor version.
EU Count
Number of execution units (EUs) in the
Render and GPGPU
engine. This data is Intel® HD Graphics and Intel® Iris® Graphics (further: Intel Graphics) specific.
Max EU Thread Count
Maximum number of threads per execution unit. This data is Intel Graphics specific.
Max Core Frequency
Maximum frequency of the Graphics processor. This data is Intel Graphics specific.
Graphics Performance Analysis
GPU metrics collection is enabled on the hardware level. This data is Intel Graphics specific.
Some systems disable collection of extended metrics such as L3 misses, memory accesses, sampler busyness, SLM accesses, and others in the BIOS. On some systems you can set a BIOS option to enable this collection. The presence or absence of the option and its name are BIOS vendor specific. Look for the
Intel® Graphics Performance Analyzers
option (or similar) in your BIOS and set it to

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
