Thank you so much for replying me! Here is how I compile: ` source /opt/intel/parallel_studio_xe_2018.1.038/bin/psxevars.sh intel64 export I_MPI_CC=icc export I_MPI_CXX=icpc export I_MPI_F77=ifort export I_MPI_F90=ifort make ` for the make file,...

The problem is compile on KNM/KNL with flag -xHost. The results become normal after I remove this flag.

we find that, the code will have problem when it is compiled with AVX512 instruction set (like compile with flag -xMIC-AVX512)

Like I mentioned before, the problem is number of iterations become abnormal. especially running with one thread per process, the number will be 0. Under other conditions(like run binary directly...
