Sorry - should have said: with the correct LD_LIBRARY_PATH - you
shouldn't need --with-batch --known-mpi-shared=1 options.

Looks like openmpi is installed in /opt/openmpi-1.2.6/ - so
LD_LIBRARY_PATH=/opt/openmpi-1.2.6/lib and
--with-mpi-dir=/opt/openmpi-1.2.6 is more appropriate.


But I see some wierd version differences between the above 2. Perhaps
you'll have not done 'make install' - after building openmpi? Or used
the wrong prefix for it?

Might be releated to the above.

Or - just let petsc install mpi to avoid these issues..

./configure --download-openmpi=1 --with-cc=icc --with-fc=ifort  --with-shared=1
