Subject: [OMPI docs] Behavior of --host and --hostfile flags on mpirun
From: Kelly Black (kjblack_at_[hidden])

Hello,

I have a question about the --host and --hostfile flags used by mpirun. Do
you have to use fully qualified host names in the arguments to the --host
option if the fully qualified domain name is given in the host file?

For example, if I have a host file like this:

# myhosts.txt
thingOne.clarkson.edu=4
thingTwo.clarkson.edu=4

Can I then use the following command?

mpirun --hostfile myhosts.txt --host thingOne -np 3 bubba

Sincerely,
kel
