Trace Map

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.

Filtering and Tagging

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:

Applications Running on Intel® Xeon Phi™ Coprocessor

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:
