how to edit Make.Linux_intel64 to get the same performance with Intel® Optimized MP LINPACK Benchmark - benchmarking

Question

My KNL platform is based on Intel(R) Xeon Phi(TM) CPU 7250 # 1.40GHz, 1 node, 68 cores, 96GB memory. I have some problems in linpack benchmark.
When I executed Intel® Optimized MP LINPACK Benchmark following: /opt/intel/compilers_and_libraries_2018.5.274/linux/mkl/benchmarks/mp_linpack
I get the good performance about 1700 gflops ( with N = 40k - compiler: mpirun -np 1 ./xhpl).
But when I download open-source on netlib hpl-2.3 and install it, the performance I got so bad ( about 700gflops, with the same size and compiler). I think my problem is install processing ( edit file Make.Linux_Intel64).
Everybody, please help me fix my problem, or please guide me if you have any idea to get good performance.
Thanks a lot.

# You can skip this section if and only if you are not planning to use
# a BLAS library featuring a Fortran 77 interface. Otherwise, it is
# necessary to fill out the F2CDEFS variable with the appropriate
# options. **One and only one** option should be chosen in **each** of
# the 3 following categories:
#
# 1) name space (How C calls a Fortran 77 routine)
#
# -DAdd_ : all lower case and a suffixed underscore (Suns,
# Intel, ...), [default]
# -DNoChange : all lower case (IBM RS6000),
# -DUpCase : all upper case (Cray),
# -DAdd__ : the FORTRAN compiler in use is f2c.
#
# 2) C and Fortran 77 integer mapping
#
# -DF77_INTEGER=int : Fortran 77 INTEGER is a C int, [default]
# -DF77_INTEGER=long : Fortran 77 INTEGER is a C long,
# -DF77_INTEGER=short : Fortran 77 INTEGER is a C short.
#
# 3) Fortran 77 string handling
#
# -DStringSunStyle : The string address is passed at the string loca-
# tion on the stack, and the string length is then
# passed as an F77_INTEGER after all explicit
# stack arguments, [default]
# -DStringStructPtr : The address of a structure is passed by a
# Fortran 77 string, and the structure is of the
# form: struct {char *cp; F77_INTEGER len;},
# -DStringStructVal : A structure is passed by value for each Fortran
# 77 string, and the structure is of the form:
# struct {char *cp; F77_INTEGER len;},
# -DStringCrayStyle : Special option for Cray machines, which uses
# Cray fcd (fortran character descriptor) for
# interoperation.
