it *definitely* is a system setup problem and your sysadmin will have to solve it. it is not a QE problem. not at all. there are a number of possible reasons why this can show up, e.g. a forgotten firewall or one non-functional node in the cluster. you have to work with your sysadmin to figure this out. axel. > > > On Wed, Jul 3, 2013 at 8:17 AM, <foster362 at gmail.com> wrote: >> >> Can you ssh between nodes (node1 to node2) and server without having to >> enter a password? >> >> On Jul 2, 2013, at 2:52 PM, DHIRENDRA VAIDYA <dhirendra22121987 at gmail.com> >> wrote: >> >> Dear PW_forum community, >> >> I am new to Quantum Espresso and I am trying to instal QE on our institute >> cluster.
