Hi John, Yea I can do this. I should be able to get to it sometime this week, at worst early next week. Do you want all of the dbg packages installed, or do you have a specific list you want? Ben

Ben,
I tried running through the CLI mode, and had the same problems. 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.
Here's what I'm getting:

/lib/modules/2.6.38.8+mpss3.4.2/extra/vnet/intel_micveth.ko /sep3.15/sep3_15-k1om-2.6.38.8+mpss3.4.2smp.ko
If I'd have to guess, the debugging symbols are missing because I don't have any of the k1om debug packages installed on the MICs themselves, i.e. "dbg" RPMs from http://registrationcenter.intel.com/irc_nas/5017/mpss-3.4.2-k1om.tar. I try to keep the packages installed directly on the MICs to a minimum as they appear to sit in a RAM disk.
Perhaps try running with CLI version of Vtune, amplxe-cl to see if it outputs anymore useful information?
Example:
export INTEL_LICENSE_FILE=28518@ftsn2 source /soft/compilers/intel/vtune_amplifier_xe/amplxe-vars.sh amplxe-cl -collect advanced-hotspots -target-system=mic-native ls -CF /usr/bin

Ben,
Thanks for re-deploying - it definitely seems to have helped. I'm now able to run the vtune GUI.
However, now I'm running into a new issue. 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).
It also outputs this set of errors when running my project:

Can you think of anything that might cause this?
Thanks again so much for your help!

The RHEL6 image was missing libXxf86vm, I've re-deployed the three servers (Ruth, Lucie, Jenny) with libXxf86vm installed. 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.
Let me know if you run into any more problems.

Ben,
I'm trying to use vtune to analyze performance of my application on the mic. I can't seem to get Vtune to run on the host node (either lucie or jenny). I keep getting the following error:
amplxe-gui: error while loading shared libraries: libXxf86vm.so.1: cannot open shared object file: No such file or directory
There seems to be a shared library file missing somewhere that I can't seem to find. Perhaps I need to add something to my linker path?
Thanks for your help!

Greetings,
I'm trying to use the JLSE MIC nodes, but I can't seem to get my home directory to show up on mic0 itself. It is available on the host, but it doesn't seem to be able to connect on the MIC. I recall a few months ago I was able to access my home dir on the mic.
Do I need to run anything to get access to the home dir?
Thanks!
