While both a serial version serial-siesta and an MPI-parallel version mpi-siesta are installed, only the former works at this point. Please contact us for suggestions on how get multiple Siesta runs started within a single program submission.
The MPI version of Siesta is run through the mpirun command:
mpirun -np 8 /opt/siesta/2.0.2/32/mpi-siesta < input.fdf
for the 32-bit version,or
mpirun -np 8 /opt/siesta/2.0.2/64/mpi-siesta < input.fdf
for 64 bit. This example uses input.fdf as an input file and runs using 8 processes.
