usermapping - user mapping entry file format
A usermapping entry is used to define alias names for a cluster user.
The user’s name known by the scheduling system is known as the cluster

execution host, the usermapping feature can solve the problem.
Each line in the usermapping entry file specifies a user name and the
host(s) where he has an account.
A list of currently configured user mapping entries can be displayed
via the qconf(1) -sumapl option. The contents of each enlisted user
mapping entry can be shown via the -sumap switch. The output follows

will be peter1. hostgroup(5) to obtain for more information about
