[QE-users] Error in reading wfc files in ph.x and projwfc.x

[Changpeng Lin]

Dear all,

Recently I compiled the latest qe v6.3 and found that pw.x worked well. But
any program (e.g. ph.x, bands.x and projwfc.x) that need to read the wfcs
generated by the scf calculation in pw.x would falied and report errors.

The error is:
forrtl: severe (24): end-of-file during read, unit 99, file
/THL7/home/xlzhou/WORKSPACE/cplin/Bi2O2Se/band_soc/./tmp/Bi2O2Se.save/wfc1.dat

and no crash file is generated. In the *.out file, it stops at:
     Reading data from directory:
     ./tmp/Bi2O2Se.save/

     IMPORTANT: XC functional enforced from input :
     Exchange-correlation      = PBESOL ( 1  4 10  8 0 0)
     Any further DFT definition will be discarded
     Please, verify this is what you really want


     G-vector sticks info
     --------------------
     sticks:   dense  smooth     PW     G-vecs:    dense   smooth      PW
     Sum        1361    1361    385               118955   118955   18197

I guess it is due to the compilation problem because if I used the qe that
was compiled by the supercomputer center and it can read my wfc files and
performs calculations.

For the compilation, I used intel impi, icc and ifort version 16.0.3 to
compile the qe v6.3. I configure it as:
./configure CC=icc CXX=icpc F90=ifort F77=ifort MPIF90=mpiifort
BLAS_LIBS="-lmkl_intel_lp64 -lmkl_sequential -lmkl_core"
SCALAPACK_LIBS="-lmkl_scalapack_lp64 -lmkl_blacs_intelmpi_lp64"
FFT_LIBS="-lmkl_intel_lp64 -lmkl_sequential -lmkl_core"

Then make all.
