Subject: AMBER: error on running parallel sander on remote node- amber9

Dear AMBER usrs,

I successfully run parallel sander on single PC with np -2, while get error
on remote node. BTW, openmpi seems to work for my test programme on remote
node.
Any suggestions for me? Thank you very much in advance.
