Ben,

That sounds like a good plan. Thanks for the help!

Hi John,

Assuming /home/jtramm/SimpleMOC-kernel/src/cpu/SimpleMOC-kernel is the actual app you're trying to profile, I can start with the packages referenced in the "Cannot locate debugging symbols" below.

My app doesn't have any outside dependencies, and it really just uses pretty normal C and OpenMP includes, so I'm guessing if it has issues with just that I will probably need them all (unless you have reason to believe otherwise).

It would be really great if you could install the required packages, as Vtune offers a lot in terms of performance analysis that can't be done any other way on the MIC. I understand the desire to keep the install bloat to a minimum, but Vtune is pretty essential to working with the MIC. I'm really in the dark as to what's going on with my application without being able to use Vtune, as even simple things like grpof don't work on there.

I try to keep the packages installed directly on the MICs to a minimum as they appear to sit in a RAM disk.

When I run vtune from the host, in order to analyze an app run on the device, it doesn't appear to be launching successfully (i.e., nothing is output to the terminal, and the resulting vtune analysis says the code only ran for a fraction of a second, when it should be at least several seconds on the MIC).

I've also updated "sep", which is the sampling kernel module for both the MIC and the host. I doesn't look like Intel included the Power sampling kernel module with Vtune Amplifier XE 2015 however, ie. /soft/compilers/intel/vtune_amplifier_xe_2013/powerdk/src.
