Zero-sized .stf file generated from ITAC

I am actually trying to use Intel Trace Analyzer and Collector (ITAC) to profile my MPI code written in Fortran.

The code does execute MPI_init at first and MPI_finalize at the end.

Following the thread of [ https://software.intel.com/en-us/forums/intel-clusters-and-hpc-technolog... ],

I was able to obtain .stf and .prot files yet the size of .stf file is zero, thus unable to open it with ITAC.

I'm using "Intel® Parallel Studio XE 2018 Update 3" for compilers, mvapich2.2.2-qlc-intel18 for MPI library, which is compatible with ITAC

and CentOS 6.4 for the OS.

Any help will be deeply appreciated.
