The easiest way to collect the data is to run the following command in the mttest directory:
% make syncperf
The syncperf target of the Makefile launches the collect command twice and creates two experiments.
The two experiments are named test.1.er and test.2.er and each contains synchronization tracing data and clock profile data. For the first experiment, collect uses a calibrated threshold for recording events by specifying the -s on option. For the second experiment, collect sets the threshold to zero to record all events by specifying the -s all option. In both experiments, clock-profiling is enabled through the -p on option.
