Hi amazing support :-)
I have a question. Does Intel VTune profiler gives an option to see the time per call....I mean time per function call... 'time in sec' spent in each function. Is there any option that can be used in the command window, that would help me know the time, in seconds, spent in each function in my C ++ application?
Thanks in advance !
Hi,
Can we use Intel VTune Profiler on Amazon bare metal instances?
I have installed Intel Parallel XE 2020 on the ubuntu 20.04.
I am trying to run the following command
vtune -run-pass-thru=--no-altstack -collect hotspots -- /usr/bin/python3 test.py which calls python3.8(system default). The vtune immediatly stops and the following crash is generated by the system.
(see pic attached)
when I run it with vtune -run-pass-thru=--no-altstack -collect hotspots -- /usr/bin/python3.5 test.py it runs fine. However, the soft I want to profile is compiled againts python3.8, so I can not profile it now.
How can I solve this problem without recompiling the software with python3.5?
Cheers.
test.py:
import time
time.sleep(60)
System:
cmake version 3.16.3
gcc (Ubuntu 9.3.0-10ubuntu2) 9.3.0
Ubuntu 20.04 LTS.

Dear Friends,
I have never used VTune profiler for instrumenting C++.
Can someone tell me why Intel VTune is better then other profiliers like valgrid, perf, gprof ? In terms of slowness & time takes for profiling hows intel compares to others ?
I want to focus on measuring application cache misses , cache performance.
Also i dont want to install Intel VTune GUI on development server, so can i load the output file of VTune created via cmd line in my local machine using VTune GUI ?
Thanks
Himanshu

Hello!
I have very big problems with parallelism on my laptop. I've written simple OpenMP parallel program like
#pragma omp parallel num_threads(8)
#pragma omp for schedule(static)
<arithmetics>
and then Hotspots analysis have revealed that parallelism is very bad. Debug version runs for a relatively long time, but it has at least some parallelism (can't attach pictures due to an error on this site :( ). Release version is much faster, but it has no parallelism at all. By the way, microarchitecture exploration analysis revealed that I have many problems with hardware (for example, bad Front-End Bound parameters).
I have no idea why parallelism is so bad even for simple arithmetic program :( The model of laptop is Acer Nitro AN515-51
P.S. I have Windows 10 and NetBeans with MinGW compiler.
