Hello,

Thank you for your kind help.

I did follow what you have said. But when I wrote "make" I ended up with the following error message:

gzip: /root/.abinit/tarballs/netcdf-3.6.3.tar.gz: unexpected end of file
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
make[4]: *** [uncompress-stamp] Error 2

OK this will prevent the netcdf error from happening ... I'll check
later why netcdf compilation hangs. Of course it won't solve your
parallelization problem.

By default openmpi builds a 64bit version of its libraries on a 64bit
operating system but abinit is build in 32bit without special flags -
this is my best assumption for your difficulties. So let's see if the
following recipe gives you better results.

As Matthieu mentioned, you'll have to "make distclean" to restore a
clean distribution. Nevertheless I suggest to compile abinit in its own
build directory i.e. never from the root of the distribution. I assume
that you have a working openmpi-1.2.8 in /usr/local (i.e. with the files
/usr/local/bin/mpif90 and /usr/local/lib/libmpi_f90.so.0.0.0) with paths
correctly sets - if yesterday's mpi hello test compiled by simply
invoking mpif90 and mpirun ... then it is okay - otherwise export PATH
and LD_LIBRARY_PATH and amend the FLAGS below. So starting from scratch ...

tar xzf abinit-5.6.4.tar.gz
cd abinit-5.6.4
mkdir tmp-build1
cd tmp-build1
../configure --prefix=/opt/abinit --enable-64bit-flags --enable-mpi
--enable-bigdft --disable-etsf-io --disable-netcdf --disable-etsf-xc
--enable-wannier90 --enable-fox --enable-xmlf90
--with-mpi-prefix=/usr/local --with-mpi-cppflags="-DNDEBUG"
--with-mpi-fcflags="-O3 -march=native"
--with-mpi-fc-ldflags="-L/usr/local/lib" --with-cpp-optflags="-DNDEBUG"
CC=gcc CPP=cpp CXX=g++ FC=gfortran CFLAGS=-O2 CXXFLAGS=-O2 FCFLAGS="-O3
-march=native" LDFLAGS="-L/usr/local/lib"
make
... and later a make install

at the end you should have a ./src/main/abinip

no panic, my gcc and openmpi are homemade, their directories are
different from yours.

If you reproduce the abinit parallel benchmark I described yesterday, it
takes a few minutes to run.
A head of the log_mpi says
  abinit : nproc,me=          2          1
  abinit : nproc,me=          2          0
  ABINIT
