Thanks.

Unfortunately parallel compilation failed, while serial had been successful.
What I did (Amber9 Debian Linux amd64 etch):

openmpi-1.2.3 compiled with

./configure CC=/opt/intel/cce/9.1.042/bin/icc
CXX=/opt/intel/cce/9.1.042/bin/icpc F77=/opt/intel/fce/9.1.036/bin/ifort
FC=/opt/intel/fce/9.1.036/bin/ifort --with-libnuma=/usr/lib

ompi_info |grep libnuma

ompi_info |grep maffinity

reported OK

Then I set:

export MPI_HOME=/usr/local/openmpi-1.2.3

Then:

make clean

./configure -openmpi ifort_x86_64

make parallel

returned

make[1]: [Sander_MPI] Error 1
make: *** [parallel] Error 2.

Then I did:

make clean

./configure -openmpi ifort_x86_64

make parallel >& errors.log

That log file is attached. Unfortunately, the very many errors of type
"undefined references to 'mpi_bcast'" are unclear to me.

Thanks for help.

./configure -openmpi ifort_x86_64

reported:

Error, MPI_HOME must be set.

OK, for my installation and bash it should be
