Often also a calendar is used to disable certain queues. Once the calendar is defined, it can even be attached to a queue on the command line with `qconf -aattr queue calendar wartung common` where "wartung" is the name of the calendar and "common" the addressed queue. 

In your case I must admit you would need for sake of easiness a hostgroup containing all GPU nodes:

qconf -mattr queue calendar wartung common@@myGPUgroup
