Objective:
As of today, if the server_dyn_res script does not return or hangs. The scheduler keeps on waiting for the script to complete the execution.
The objective of this design document is to propose the solution for this hang issue.
Interface 1: New Configurable Scheduler attribute: server_dyn_res_prog_timeout
- Visibility: Public
- Change Control: Stable
- Details:
- Admin can configure the scheduler attribute "server_dyn_res_prog_timeout". Default value is 60 seconds.
- Usage :
qmgr -c "set sched server_dyn_res_prog_timeout = 15"
- PBS will start polling from the time the server_dyn_res program/script starts executing and will wait for "server_dyn_res_prog_timeout" time. After the timeout, the interaction with the script will end and the scheduler will log a timeout info message.
