Intel® VTune™ Amplifier XE and Intel® VTune™ Amplifier for Systems Help

Window: Summary - TSX Exploration

Use the Summary window as your starting point of the performance analysis with the Intel® VTune™ Amplifier. To access this window, select the TSX Explorationviewpoint and click the Summary sub-tab in the result tab.

The TSX Exploration viewpoint is enabled for TSX Exploration and TSX Hotspots analysis results and targeted for Intel® processors supporting Intel Transactional Synchronization Extensions (Intel TSX). Depending on the analysis type, the Summary window provides the following application-level statistics in the TSX Exploration viewpoint:

Analysis Metrics

For the transactional success analysis, the VTune Amplifier provides the following metrics:

VTune Amplifier classifies aborts by the following reasons:

In the example below, most of the transactional executions were aborted due to a data conflict:

Switch to the Bottom-up window to analyze the Data Conflict statistics per function.

Abort Cycles Histogram

This histogram shows the number of aborts happened for transactions with a specific cycles duration.

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 VTune Amplifier.

Collection start time

Start time (in UTC format) of the external collection. Explore the Timeline 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 Timeline pane to track the performance statistics provided by the custom collector over time.

CPU Information

Name

Name of the processor used for the collection.

Frequency

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

Name of the Graphics installed on the system.

Vendor

GPU vendor.

Driver

Version of the graphics driver installed on the system.

Stepping

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.

Note

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 Enabled.
