Polaris hostfile is incorrectly interpreted by Thallium

[lukemartinlogan]

Polaris use $PBS_NODELIST file. This stores hostnames, which are resolved to different ip addrs. These addrs are resolved in different orders. This results in the hostname resolution containing ip addresses from different domains. This leads to problems in thallium, which does not seem to support networking across domains, leading to HG_NOENTRY issues.

We need to find a way to create a hostfile containing only IP addresses from the same domain.

To get the host names

ip addr
