The command-line tool can also be used to administer Gurobi Remote Services and Gurobi Compute Server. The format of an administrative command is simply:
gurobi_cl [--command]*Available administrative commands are:
gurobi_cl --status.
Administrative commands can be run from any machine on the same
network as the server. All except --status prompt you for the
administrator password. Alternatively, you can provide the password
on the command line using the --adminpassword= command. For
security reasons, if no initial administrator password is specified
(via the grb_rs.cnf file), server administration is disabled.
One additional command-line argument that you may need in conjunction
with these commands is --server= (--servers= is also
accepted). This argument specifies the machine where the requested
command should be performed. If you omit this argument, the machine
name will be pulled from the COMPUTESERVER= line of your client
license file.
Note that the --joblimit and --newadminpassword
commands can only be applied to a single server at a time.
If you specify multiple servers (either through the --servers
switch or through your client license file), the command will only
be applied to the first member of the list.
The following shows sample output from gurobi_cl --status...
