  3. PP-725: new "keep <select>" option for "pbs_release_nodes"

Overview

This is to enhance the "node ramp down" feature, by introducing a new option "-k <node count>" ("k" for "keep") to the pbs command "pbs_release_nodes". This will allow users or admins to retain some of the sister nodes (exec_host), while performing node ramp down operation. The number of sister nodes to be kept is specified by the argument to this new option.

Technical Details

Interface 1:  -k <node count>

...

• The count argument is internally converted to a "select" string parameter which will be passed to "pbs_relnodesjob()" using its "extend" argument which is of type "char * "
