Yes, it works fine for (torque 2.3.5, maui 3.2.6p21), but only when one 
license count is required. It does not work anymore when using "-l 
software=whatever:2", "-l software=whatever+2" or "-l gres=whatever:2". 
The job is rejected by maui, telling that it cannot allocate the 

It seems that moab is able to handle this as explained in maob 
documentation, paragraph 13.3.2 Resource Manager Extension Values.

However managing a license count greater than one would be very useful 
with softwares that use tokens instead of simply one license per job. In 
such cases, the sofware request several tokens (that could be declared as 
global generic resourse, GRES) and the number of tokens depends on many 
parameters such as the cpu number used during the job and the type of 
task carried out by the software.
