Trace Collector not Capturing OpenMP regions!!!

HPC_SHIDUR — Thu, 28 Oct 2021 16:51:15 GMT

Dear all

I am trying to collect the data from my hybrid code and analyze with ITAC. However, the Trace collector is not recording OpenMP regions of my code at all even though I have switched on -tcollect in my makefile for compilation. The commands I have used is as follows:

IN MAKEFILE FOR COMPILATION:

CFLAGS = -Wall -Wshadow -std=c99 -O3 -qopenmp -tcollect -g #-march=core-avx2 -mtune=core-avx2 -g

CC = iccc
MPICC = mpiicc
LDFLAGS = -qopenmp -tcollect #-L /opt/local/lib/mpich-devel-clang80/ -L /opt/local/lib/ #-lefence #-lprofiler #-l efence

SET UP ENV VARIABLE:
export OMP_NUM_THREADS=4
export VT_PCTRACE=5

RUN THE PROGRAM with -trace :
mpirun -genv VT_LOGFILE_FORMAT=SINGLESTF -trace -n 8 ./speed_test_diracoperator -i ./speed_test_diracoperator.in

Could anyone please give me information about this problem?

The figure below shows that the OpenMP section is 0 sec 0%:
