Hi Reuti

Thanks for the response.

My requirement is that when I reschedule a spectre job running on host x to resume on host y.

To achieve what can configuration needs to be in place? If checkpoint configuration is the answer how do I go about?

Regards
Veeru!

the job quits itself after writing the checkpointing file by the  
sigtstp? When you only defined the suspend and resume method, then  
the job stays on the node and won't get rescheduled at all. Therefore  
I don't understand your question in detail.
