Help: Using Intel Thread Profiler on Linux

I believe that thread profiler is a Windows only software as far as I can tell. But where do I find the linux install?

From what I understand; I can turn on the -tprofile switch on ICC then I can dump the info and open it in the Windows version of thread profiler. So while I have ICC and VTUNE installed on Linux, I don't know what I have to do to get the thread profiler switch on ICC to work?

I get that following response from the compiler:
icpc -g -O3 -tprofile -c cmd_lreader.cpp
(0): catastrophic error: tp10.ini not found; Intel(R) Threading Tools must be installed

compilation aborted for cmd_lreader.cpp (code 4)

-tprofile would require that you installed the separately licensed Thread Profiler for linux:
https://registrationcenter.intel.com/RegCenter/Download.aspx?productid=771&sn=
and set both the thread profiler and icpc environment variables.
As you said, linux thread profiler creates files which appear intended to be read in Windows thread profiler.  I haven't been able to find out what may be required to take that step successfully.

That URL should present a login screen which you could use if you have registered any Intel software tool application, either evaluation or purchased.  The top level URL will offer to register any such application and open an account for both that site and premier.intel.com support.
If you are alluding to the fact that thread profiler for linux is not present on the screen which offers evaluation licenses, that is true, but does not mean there is no such thing.  I would agree also that I could not recommend purchase of this product without evaluating it, and I find the openmp_profile option of the compilers sufficient in practice.
I don't know whether anyone has requested an evaluation of the linux version; if you have the Windows version, which appears to be expected, you could submit a request on premier.intel.com to find out what the policy may be.  It's even possible that omission from the evaluation menu is an oversight.

Thanks Tim,
This is helpful.
First that, I was not aware of openmp_profile option, I will try that out. and also request the evaluation version of Linux version for the thread profiler (or enabling the non-commercial download for the same.)

Best regards,

Thread Profiler for linux also includes binary instrumentation.  Once downloaded and installed, use the 'tprofile_cl' executable to run TP on your program.  It will create a 'threadprofiler' directory with files that can be opened and viewed in the Windows version of Thread Profiler.
