Trace1 Sample Application

Description

Trace1 shows how to setup MPI tracing and log the data to a circular file. A
circular file is similar in concept to a circular buffer; it allows trace data to be
continually written without taking up too much disk space.

Trace1 logs the function entry points for all MPI functions internal and external
and is useful when tracking down application problems.

To convert the circular files to normal “flat” files, please refer to the CircFileRead sample application.
