I am trying to use VTune Amplifier XE 2015 to analyze application on Xeon Phi in the native mode.
Without VTune, the application on Xeon Phi runs normally (follows script: run.sh).
#!/bin/sh
export LD_LIBRARY_PATH=/tmp
/home/atrianta/clstmocrtrain
With VTune, the elapsed time is zero but VTune runs the application normally.

However, VTune analyzes without a problem /tmp/matrix.mic (from the example here: https://software.intel.com/en-us/articles/how-to-analyze-xeon-phi-coprocessor-applications-using-intel-vtune-amplifier-xe-2015).
Can anyone help me figure out this problem?
To be more specific,
ldd command for my programm on PHI resulted on this :
linux-vdso.so.1 => (0x00007fffde5ff000)
libz.so.1 => /usr/lib64/libz.so.1 (0x00007fe086917000)
libimf.so => not found

libirng.so => not found

libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007fe0863ee000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007fe0861dc000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007fe085fbf000)
libc.so.6 => /lib64/libc.so.6 (0x00007fe085c67000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007fe085a63000)
/lib64/ld-linux-k1om.so.2 (0x00007fe086b2b000)
So I had copied from /opt/intel/composer_xe_2015.1.133/compiler/lib/mic/ folder the "not found" libraries to /tmp/ of PHI (as I did with libiomp5.so for the matrix.mic example).
IF IT HELPS, I also ran VTune after i set the following variables :
export AMPLXE_LOG_LEVEL=TRACE
export AMPLXE_LOG_DIR=./log
but it stacks for my program on :
