Setting Up Access to Remote Hosts

To run jobs on remote hosts, you must set up access to these hosts by allowing use of the ssh command without specifying a password. If you have a firewall, you must allow access across the firewall. Setting up access is described in the subsections below.

Remote jobs can be submitted to Linux hosts, but not to Windows and Mac hosts.

• If access has been set up previously, you do not need to do so again.

• If you plan to run parallel or distributed jobs that involve more than one host, you must also set up passwordless access between these hosts. Passwordless SSH can sometimes be used even between a remote host and itself (e.g., when the compute host also is the queue host). The special case of clusters is discussed in Configuring Clusters.
