Illustrated by an exemplary run of the spin glass server.
Given an instance of a two-dimensional quadratic 3x3 lattice on a torus with periodic boundaries.

The following represents the definition of a spin glass instance.
Note that the formerly used instance types (pm, gauss, pm3, gauss3, sk, and 2d) are obsolete, but still supported.

Name: 3x3 system as a test for this nice service
Problemtype: gauss
Size: 3

Machine: Intel Pentium 4 CPU 2.80GHz

result:

Energy (per spin): -0.98580397885
Magnetization (per spin):0.111111111111
CPU-Time (min:sec.1/100): 0:00.00

Here comes an optimal spin configuration:

total number of spins: 9
spins up: 4

CONFIGURATION_BEGIN
2 4 5 8
CONFIGURATION_END

Interpretation of the result:

The ground state was computed on an Intel Pentium 4 CPU 2.80GHz.
The computation finished on Fri Oct 1 12:47:43 2010.
It took < 0.01 seconds cpu time to compute an exact ground state.
The energy per spin is -0.98580397885.
The magnetization is 0.111111111111.
This configuration is mentioned explicitly between 'CONFIGURATION_START' and 'CONFIGURATION_END'.
The spins 2, 4, 5, and 8 are all oriented "up", the others (1, 3, 6, 7, and 9) "down".
(The magnetization per spin is: (5-4)/9 = 0.111111111111).

The command-line-client has also the option "-t short", to only give a short output that does not specify the used hardware.
