How to aggregate heterogeneous entire clusters into “one big cluster” for cross-cluster job submission

The information disposed by qmgr -c "p s " , pbsnodes -av , qstat -fx , qstat -anws1 are in the memory. Any other attributes you change on any object is stored in database immediately - like form qmgr Node states are not updated in the database, since they are transient in nature, it is not stored in the database. you can get the real time job information by running qstat -fx , tracejob , pbs_dtj You can use the PBS Libraries and develop code which suits your requirement , plese f…

Also, you can use -F json with qstat and pbsnodes commands which will dump results in json which then can be easily parsed by your programs.
Usage: qstat -f -F json
pbsnodes -av -F json
