The program compiled for one processor can be started from a command line:
md < md.in > md.out
where md.in
is the main input file and md.out
is output. Names
of input and output files may be arbitrary
In the case of parallel execution, the input file must be always called
md.input
. The program starts for example as:
mpirun -np 4 mdp > md.out
where number of processes is 4 and md.out
is name of the output file.
Other arguments for mpirun
command can be given. Often
mpirun
can be invoked only from a queue batch script, see
the rules in your computer center. Sometimes command poe
is used
to start a parallel program
