Compare Two Trace Files


Compare two trace files with the help of the
Comparison View
. To open a Comparison View for the original application trace file (
poisson_sendrecv.single.stf
), go to
View > Compare
. In the dialog that appears, choose the trace file of the revised application (
poisson_icomm.single.stf
). The Comparison View shows an Event Timeline for each trace file and a Comparison Function Profile Chart.
Zoom into the first iteration in each trace file. The Comparison View looks similar to:
