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:
Comparing the First Iterations
In the Comparison View, you can see that using non-blocking communication helps to remove serialization and decrease the time of communication of processes.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
