I've tried to use Intel VTune Performance Analyzer 9.0 for Linux*, but it seems to work only with 32-bit applications.
Can you please let me know if it is possible to use VTune for tuning 64-bit
I installed VTune on 64 Red Hat Linux (CPU is Opteron AMD 4 cores). I used gcc compiler. It produces 64bit modules by default (or with -m64 key)and VTune can not recognize their format. If gcc option -m32 is used then it works OK.
Could you explain why it can be?
