Dear All;
I am interested to run NWCHEM-6.1.1/open-mpi-1.4.1 program over two nodes systems ( two core-de-quad PC's connected by ordinary internet cables). I know that under these conditions I will not gain any speed. I tried the command;
mpirun -machinefile my_hostfile -np 8 nwchem input
Where my_hostfile is:
localhost slots=4
10.0.0.203 slots=4
The environmental variables were set in the two nodes.
I got no output nor error messages .
The statements used to compile the code is:
export LARGE_FILES='TRUE'
export USE_NOFSCHECK='TRUE'
export LIB_DEFINES -DDFLT_TOT_MEM=16777216
export NWCHEM_TOP=/home/mohamed/nwchem-6.1.1
cd $NWCHEM_TOP/src
export NWCHEM_MODULES='all'
export NWCHEM_TARGET=LINUX64
export USE_MPI='y'
export USE_MPIF4='y'
export USE_MPIF='y'
export MPI_LOC=/home/mohamed/ompi-1.4.4
export MPI_LIB=$MPI_LOC/lib
export MPI_INCLUDE=$MPI_LOC/include
export LIBMPI="-lmpi_f77 -lopen-pal -lopen-rte -lotf "
export USE_64TO32='y'
make realclean
make nwchem_config
make 64_to_32
make realclean
make FC=gfortran
Do I need to recompile the code ?
I appreciate any help.
Best Regards
Makhyoun
