Dear users

I want to run a quantum espresso program (with passwordless ssh). I
prepared a hostfile named 'texthost' at my input directory. I get this
error when I run the program:

texthost:
# This is a hostfile.
# I have 4 syetems are paralleled by mpich2
# The following nodes are that machines I want to use:
#client3_at_master.cluster.umz slots=4
khalili_at_client1.cluster.umz slots=4 max-slots=4
#khalili_at_client2.cluster.umz slots=4 max-slots=4
khalili_at_client3.cluster.umz slots=8 max-slots=8

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

error:
ssh: Could not resolve hostname texthost: Name or service not known

after press ctrl+c:
^C[mpiexec_at_master.cluster.umz] HYDU_sock_write (./utils/sock/sock.c:291):

Could you help me please?
