Trace Map enables you to zoom into the relevant subsets of large trace file Charts. It represents a miniature view of the MPI function activity over time. By default, the MPI function activity is shown in red color.
The filter mechanism in the Intel® Trace Analyzer does not cover counters. Therefore the Counter Timeline is independent of the View filter settings.
Tagged cells are emphasized by a small additional frame around the cell in the color of the alphanumerical entry in the cell. A cell is tagged as soon as a single tagged message falls into that cell. Here is an example of tagging MPI_Allreduce function in Collective Operations Profile:
To simplify interoperability between Intel® Trace Analyzer (ITA) and Intel® VTune™ Amplifier XE, ITA can generate a command line for mpirun / mpiexec.hydra targeted at analyzing specific processes with VTune Amplifier. It takes your original command line and modifies it in a way that you can run VTune Amplifier with it.
This Reference Manual documents the Intel® Trace Collector 9.0.3 release.
Intel® Trace Collector 9.0 Update 3:
- Support for OpenMP* regions. See Recording OpenMP* Regions Information for details.
Intel® Trace Collector 9.0:
To generate a trace file from an MPI application running on an Intel® Xeon Phi™ coprocessor, you need to use the Intel® MPI Library, the Intel® Trace Collector libraries, and a compiler that can generate an executable file compatible with the targeted Intel® Many Integrated Core Architecture (Intel® MIC Architecture). Do the following steps to complete these tasks:
The first step always is to run the application so that libVTmc can intercept all MPI calls. The available methods to achieve this are exactly the same as for normal performance analysis with libVT or libVTfs:
Relinking the application
check command line option of mpiexec (Intel® MPI library only)
