[Pw_forum] Build QE for Intel Phi native run

[Hideaki Kuraishi]

Hello,

I have been trying to build QE 5.0.2 with Intel Compiler 15.0.0 and Intel MPI 5.0 to run in native mode. However, though configure is fine, it fails at make phase with segmentation fault error as follows.

--------------------------------------
            :
mpiifort -openmp -o bands_FS.x bands_FS.o -L$MKLROOT/lib/mic -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64 -liopm5 $MKLROOT/lib/mic/libmkl_lapack95_lp64.a -liomp5 $HOME/mkl/lib/libfftw3xf_intel.a -L$MKLROOT/lib/mic -lmkl_intel_lp64 -liomp5

/opt/intel/impi/5.0.0.028/intel64/bin/mpiifort: line 729:  5630 Segmentation fault      (core dumped) $Show $FC $FCFLAGS "${allargs[@]}" $FCMODDIRS $FCINCDIRS -L${libdir}${MPILIBDIR} -L$libdir $rpath_opt $mpilibs $I_MPI_OTHERLIBS $LDFLAGS $MPI_OTHERLIBS

( cd ../../bin ; ln -fs ../PW/tools/bands_FS.x . )

            : 
--------------------------------------

If someone has experienced the same error, could you please share the information on how to solve this?

My procedure is...

(1) Configure
export CC=mpicc
export FC=mpiifort
export F90=$FC
export MPIF90=$FC
export AR="xiar"
export CFLAGS="-mmic -openmp"
export FFLAGS=$CFLAGS
export FCFLAGS=$CFLAGS
export BLAS_LIBS="-L$MKLROOT/lib/mic -lmkl_intel_lp64 -liomp5" 
export LAPACK_LIBS="$MKLROOT/lib/mic/libmkl_lapack95_lp64.a -liomp5" 
export SCALAPACK_LIBS="-L$MKLROOT/lib/mic -lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64 -liopm5"

$ ./configure --enable-openmp --enable-parallel

(2) Build
$ make pw 2>&1 | tee LOG.make

Best regards
Kai
