Estimating FLOPS

I have Intel(R) Core(TM) i7-4800MQ CPU @ 2.70GHz which is Haswell based processor. I want to estimate FLOPS of an application. I am using Intel VTune Amplifier XE 2015. wondering if anybody knows how to find FLOPS?

I tried following steps on https://software.intel.com/en-us/articles/estimating-flops-using-event-b... but I don't find Processor Event Name on the pages in VTune. wondering if anybody has successfully done this on Haswell processor.

VTune fails to collect usual data on MIC

Hello,

I've got troubles with VTune for collecting data on a native MIC application, after we upgraded MPSS to 3.5 and Intel Tools to 2015 update 3.

Here is a log of what happens and the debug logs that VTune created as an attachment.

Probably the key line is:

tb5gen_Add_Sampling_Data returned error "Unknown reason"

There is some data, but no info based on the call stack like "top/down", and the result is therefore not really useful.

Sincerely, HC

Extracting results based on time ranges

Hello, I am interested in using Vtune to profile a system. I have run a project and gathered the results. I am looking at the hardware event samples for a specific cpu. EG: All hardware events for CPU 0. The problem I am having is that I want to look at the results based on small time intervals. Basically I want to see the results for every 15ms.

Need help getting information from Vtune using time ranges

Hello,

So I am using Vtune to profile my system while I use a generated workload. What I am trying to do is get the data for 15ms intervals for the entire run. Here are some of the things I am running:

System profiling

General exploration -> Hardware event sample count viewpoint

Bottom up view

Core, HW context, Function, Callstack -> (I am filtering in by 1 cpu. So my data is only for 1 cpu)

Unable to View Statistic of OpenMP Region CPU Usage Histogram

Hi,

Currently, I'm running analysis on the executable file generated from the compilation of C source code.

However, at the Summary window, certain OpenMP regions' CPU Usage Histograms are not displayed at the GUI, and some of them do.

Attached is the screenshot of Summary window. Hope it'll help to clarify my statement above.

Is there any solution to this problem?

 

Thank you.

Linux: 4.0 is not a supported linux release

Hello all,

similar to this issue back then with Linux 3.0 https://software.intel.com/en-us/forums/topic/282300 I'm now greeted by the annoying error message that "4.0 is not a supported linux release". The differences to the last 3.x release are not large, so this restriction is rather annoying. Is there a way to bypass it? Or is there a beta release ready to be tested to circumvent this issue? I've tried with the latest VTune Amplifier XE 2015 Update 3 release to no avail.

thanks

Cannot locate debugging symbols for file `/tmp/amplxe-tmp-lab/xxxxx/

Hi,

I am trying to profile an application using the remote analysis workflow as mentioned in this link.

https://software.intel.com/en-us/node/496398#46F7A60C-C2A4-4EEA-9460-BC3...

When i try to the run the profiler using GUI as well as command line, i am getting these warning messages:

amplxe: Using result path `/home/xxxx/vtune_trial/xxxxxx/r002hs'

amplxe: Executing actions 16 % Resolving information for `bash'
