[mvapich-discuss] osu benchmark over 10GE - hydra_pmi_proxy issue

[LaoTsao]

imho, this is really not mvaipch issues
the two vm on separate host need to talk to each other first
if you setup nic as bridge network then the two vm can use the hosts' ip network to talk to each other
if you use private network or nat then one need to open these nic between two hosts,
