Dear all

I am trying to an example in a parallel system includes 1 server and 3
nodes. I want to use 2 nodes as I mentioned in texthost. When I run this
command I get an error:

mpirun --hostfile texthost -np 2 /home/client3/espresso-5.0.2/bin/pw.x -in
AdnAu.rx.in | tee AdnAu.rx.out

My hostfile:
# This is a hostfile.
# The following nodes are used for calculations
# # is the server
# nodes:
khalili at slots=4 max-slots=4
khalili at slots=4 max-slots=4
#khalili at slots=8 max-slots=8

Any help is really appreciated.
