I am trying to use graphlab with an openstack cluster. I managed to get the gl-ec2 script to "launch launchtest" with one slave per the tutorial.
As instructed I tried "gl-ec2 update" which compiles for a while and then fails with
"ssh could not resolve hostname <valid-openstack-instance-identifier>".
This is part of a call to
mpiexec.openmpi -hostfile <localpath> -nolocal -pernode rsync -e 'ssh -o StrictHostKeyChecking=no -i <pathtokey> -avz --exclude ...
Due to the dynamic nature of our cloud, we don't have DNS entries for the created VMs. Am I right in thinking that this is the problem here? Is there a way to tell the script to use IP addresses instead?
