HPL compiled with OneAPI HPC toolkit failed to converge

[PingLin]

I have tried to compile HPL using the new 2025 intel OneAPI HPC toolkit to run benchmark test on RedHat Linux Enterprise 8 and 9. I downloaded the Netlib HPL source code from http://www.netlib.org/benchmark/hpl/ .

And following the steps suggested by the manual:
1. Download and extract the source code.
2. Copy the makefile:
$> cp setup/Make.Linux_Intel64 .
3. Edit Make.Linux_Intel64 as appropriate
4. Build the HPL binary:
$> make arch=Linux_Intel64
5. Check that the built binary is available in the bin/Linux_Intel64 directory.

I have played with different changes on Make.Linux_Intel64 file. While they all compiled without complains. During the test run, all 864 tests completed and failed residual checks.

Here is one of the changes I made to the Make.Linux_Intel64 file (parts that changed shown).

# - Message Passing library (MPI) --------------------------------------
MPdir = /opt/intel/oneapi/mpi/2021.15/
MPinc = -I$(MPdir)/include
MPlib = $(MPdir)/lib/libmpi.a

# - Linear Algebra library (BLAS or VSIPL) -----------------------------
LAdir = $(MKLROOT)
ifndef LAinc
LAinc = $(LAdir)/include
endif
ifndef LAlib
LAlib = -L$(LAdir)/lib \
        -Wl,--start-group \
        $(LAdir)/lib/libmkl_intel_lp64.a \
        $(LAdir)/lib/libmkl_intel_thread.a \
        $(LAdir)/lib/libmkl_core.a \
        -Wl,--end-group -lpthread -ldl
endif
# - Compilers / linkers - Optimization flags ---------------------------
CC = mpiicx
CCNOOPT = $(HPL_DEFS)
OMP_DEFS = -qopenmp
CCFLAGS = $(HPL_DEFS) -O3 -w -ansi-alias -z noexecstack -z relro -z now -Wall

I have changes the settings and none is working. 

My question is, what is the appropriate change for the Make.Linux_Intel64 file?

The Intel® Distribution for LINPACK Benchmark may contain additional optimizations compared to the reference Netlib HPL implementation. Is there anyway to find out the additional optimizations?

The output from the failed test is attached.

Additional notes: compilation works with GCC (mpicc) and linked with MKL. And it appears to be the way many compilation is done. And my question is why OneAPI C compiler doesn't work?
