Hi,


yes you can insert specific start and stop points. When I used VTune I needed to include this header in the file containing the critical code sections:  "#include <ittnotify.h>". I started the measurement on the C++ level with "__itt_resume();" and stopped it with "__itt_pause();". If I remember correctly the measurement starts in paused mode when using custom start/stop points. During compilation I needed to set these cmake flags:


-Dwith-includes=<path/to/vtune_amplifier/include/> \
-Dwith-libraries=<path/to/vtune_amplifier/lib64/libittnotify.a> \
-Dwith-debug=-g \

In general VTune is well documented and this should be explained in the documentation in more detail.


Best,
Jari

Hi Jari,

Thank you for your reply. This is very helpful to me.

If I want to test the calculation time of STDP and neuron respectively in the simulation stage, Can I only use the method of inserting specific start and stop points into the source code?
