Hi,
I running vtunes on SKY-H 4+4e platform on Ubuntu14.04 to profile the caffe framework. When I run the app for 100 test images it works perfectly but when I increase it to 500 images, it displays the message " The data cannot be displayed: there is no viewpoint applicable for data" for Memory Access profile and Advanced hotspot too. It works for Basic Hotspots.
In the Collection log:
Finalization completed successfully
Results is ready for analysis.
Cannot load data file '<path_to_data_file>"TBRW_doind(tbrwFile->gethandle(),streamIndex)"failed:invalid string(97))
Thanks,
Siddhesh

Hi Siddesh,
Vtune has a default file size collection of 500 MB . Looks like your file size might be an issue when your collecting data for 500 image. Try increasing the file size on the analysis target tab in Analyzer.

Hi Pallavi,
Thanks for your reply. I tried to increase the collection size to 10500 but the problem still persists. I am getting the same error message as before.

Hi Siddhesh,
Can you disable the ptrace_scope in Ubuntu and please check if it works then?
You can set the ptrace_scope value to "0", if it was set to "1".
echo 0 | tee /proc/sys/kernel/yama/ptrace_scope
You can verify if its set to "0" now :- "cat /proc/sys/kernel/yama/ptrace_scope".
Note:- You need sudo permission to set the ptrace_scope
If the above setting didn't help you, can you also try to disable "nmi_watchdog" just for profiling and then enable it back once done with profiling :-
Disable watchdog : -
echo 0 | tee /proc/sys/kernel/nmi_watchdog
Please do let us know if this solves the issue.
Regards,
Sukruth HV

Hi Sukruth,
The ptrace_scope and nmi_watchdog were disabled before running the profiling tool, as mentioned in the installing instruction manual(prerequisite). Also on rebooting the system, I disable them each time. I am not sure if I am missing something else here.
Thanks,
Siddhesh
