[Beowulf] Functionality of schedulers

[Jon Tegner]

Hi list!

Is there any scheduler which has the functionality to automatically put 
a running job on hold when another job with higher priority is submitted?

Preferably the state of the first job should be frozen, and saved to 
disk, so that it can be restarted again when the higher priority job has 
finished.

Is this at all possible (we are using torque/maui, and I couldn't find 
this feature there)?

Regards,
