I am a newbie using vtune
I am trying to profile a portion of Quantum Espresso (http://www.quantum-espresso.org/)
However, when run under (or attached to) VTune gui, program raises a file handling error signal (38) and crashes. The program runs normally otherwise.
I have tried AMPLXE_RUNTOOL_OPTIONS="--profiling-signal <another signal>" where another signal is 16, 39 etc. however, this did not resolve the situation.
What might be going wrong?
I am using the basic hotspot analysis.
The program fails writing a file to the disk, citing a signal 38 was caught (although I am using a different profiling signal as mentioned above)
Update: Apparently it is not a file written to a disk this time.
