If you used the previous version of Intel® GPA Platform Analyzer, your transition to using the new version of the tool should be very straightforward. However, note the following differences:
- Tracing enabled by default: You do not need to select this option from the Intel GPA Monitor Preferences configuration pane to enable this feature.
- Tracing configuration options minimized: To configure tracing, you need to set the Tracing Duration option only, via Intel GPA Monitor> Profiles >Tracing. This option replaces the Trace Buffer Size option. The options for collecting DirectX* data, hardware context, and internal data are no longer available since the new version of Intel GPA Platform Analyzer automatically collects the data necessary for creating and viewing all the data charts.
- Android* support: Besides traditional support for the Windows*-based applications, Intel GPA Platform Analyzer now supports Android applications running on Intel Atom™ processors with PowerVR* Graphics.
- GPU software queue: On Windows, the Platform View of the new version of Intel GPA Platform Analyzer provides data on GPU usage and displays a software queue for GPU engines at each moment of time.
- No application startup capturing: The option for capturing the application startup is no longer available. Instead, select a sufficiently large trace duration (such as 5 seconds) and use an Intel GPA trigger (such as Application Time> 3) to approximate this feature. However, the new data collection methods being used in Intel GPA Platform Analyzer cannot capture trace data beginning with the exact start of an application.
- No support for tracing Media and OpenCL™ kernels data: The development team is considering adding these features in a future release of the product.
- No Summary view: Consider using the new Platform Analysis view that provides additional features and should provide a sufficient representation of the application execution on GPU and CPU cores. A separate Summary view is available with the Intel VTune™ Amplifier.
Overall, the new version of Intel GPA Platform Analyzer provides an advanced platform analysis mechanism that can more quickly isolate and identify task synchronization issues across the CPUs and GPU.
