[molpro-user] How to run molpro in parallel?

[Shenggang Li]

I tried to run in serial, 2 processors on a single node, or 2
processors on two nodes, but it ended with the same error message. 
The hostname shouldn't be a problem, as I have sucessfully run NWChem,
as well as molpro build without infiniband support.  What is the
registry file anyway?  Thanks for your help!
