> Hi all,

> I have a scenario here, I am trying to explain this in steps.
>  
> 1. I have some jobs running in the cluster, based on the priority of the queues (Few queues have higher priority than others & so on).
>  
> 2. I am also having a VIP.queue which is having the highest priority among all the queues. So ofcourse jobs which has been submitted through vip queue will definitely go up in queue, as I have shown below.

> 100    0.50500        job_name1      usr1       r              normal.q at exehost             32
>
> 101     0.50500      job_name2       usr1       r             normal.q at exehost              16
>
> 102     0.50500       job_name2      usr1       r             normal.q at exehost              32
>
> 103     0.50500        job_name3      usr2      r             normal.q at exehost              128
>
> 104     0.50973         job_name4      usr3     qw              VIP.q at exehost.              64
>
> 105     0.50973         job_name5      usr3      qw           normal.q at exehost         32
>
> 106     0.51514         job_name6        usr4     qw            normal.q at exehost         16
>  
> 3. Now These VIP Jobs are very important jobs & I want these jobs to run ASAP, Hence I will checkpoint the lower priority jobs which are running right now.
>  
> 4. Suppose job id 100 & 102 I have selected for checkpointing & send checkpointing signal to those jobs, & It has taken 2 hours to chekpoint these jobs.
>    I do not want any other job to run on these resources during this duration of 2 hours.
>    Because there is a possibilty that small jobs can get the resources & start running  
>  
>  
>  
> Kindly help me How can I be able to reserve the resources for the duration of checkpointing so that any other un important job can not able to start.
