[Pw_forum] Build QE for Intel Phi native run

[Hideaki Kuraishi]

Dear Filippo, Fabio

Thank you for the comment.
Yes, core file is generated and will analyze this.

So far I have tried your suggestions but situation didn’t change and the same error
occurred. Even when I used older versions of Intel compiler, v13 and 14,
the error was reproduced. I will try this on more using another system this week.

Best regards
Kai

Dear Hideaki,
 ,
Fabio Affinito can advise for the Intel Phi part however I do suggest to run configure in this way:

./configure --enable-openmp --enable-parallel --with-scalapack=intel

and only after edit the make.sys to eventually modify the libraries patch and names. The configure should be able to pickup MKL and ScaLAPACK if the environment is set correctly.

The problem you see is additional to the one I noticed while ago with the latest 15.x Intel compiler. If you can systematically reproduce this compiler seg fault then it is worth to file a bug report to Intel. It mention a core file... do you have one in the PW/src directory?

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.

--------------------------------------

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
