You need to use "scatter" in conjunction with "scrun" to distribute stdin 
from the master node to the client node(s). F.e. to distribute your input 
file to only the first process of the job (rank 0), you should do 
something like:

scrun -nodes=8 scatter -node 0 == program < input

This is covered in the man pages.
