do you want to submit the you with an resource reservation inside the advance reservation?
No. I am expecting that the '-R y' passed to qsub creates the advanced reservation based on the other resources requested by the jobscript. Then assing the job to that advanced reservation. Is this the expected behaviour? Is this something that can be done?
The question is: is the job eligible to run as the next one or is it somewhere down the list of waiting jobs?
The job is requesting i.e. 2 slots, is down in the list of waiting jobs, and without reservation is overcome by other jobs of almost the same urgency that require only one slot.
For a resource reservation to work, it's also mandatory to submit jobs with reasonable h_rt/s_rt requests. Otherwise the default in the scheduler will be taken and due to the default "infinity" may avoid any reservation.
the job was submitted with a well defined value of hard runtime, i.e. h_rt=600
The man page of `man sched_conf` explains it. NB: SGE judges "infinity" being smaller than "inifinity", hence jobs without specified runtime will always slip in as they are entitled for backfilling. It's better to put there a fixed high value as default_duration in the scheduler configuration like "9999:00:00".
