PBS Pro Community Forum Li= nk: http:/= /community.pbspro.org/t/pp-289-unique-job-ids-up-to-1-trillion/465
PP-289 - As an ad=
min, I would like to have unique job ids up to 1 trillion job ids Closed
Currently the largest possible Job ID which PBS can hold is "9999999". W= hich is a bit low for sites submitting lot of jobs. With new enhancement th= e largest possible Job ID that PBS would now hold will be "999999999999". T= hus the range will be (0 to 999999999999) with a total of 1 tr= illion unique job IDs.
qmgr obj=3D svr=3Ddefaul= t: Cannot set max_job_sequence_id < 9999999, or > 999999999999
qmgr: Error (15225) retu= rned from server
&= nbsp; Example: Given below an example = in which we can see the change in qstat output format:
= &nb= sp; = Previous Output: If max job= id is "9999999" and server name is "servern= ame-cent7" then output displays in Job id column like 9999= 999.servernam
&nbs= p; &= nbsp; &nbs= p; New Output: Now, if max job= id is increased to something greater than "9999999" like = set to higher limit "999999999999" then output would be li= ke 999999999999.servernam
&nbs= p; &= nbsp; Note: Increased the width of Job Id column(from 17 to 22 characters) only.
= Given below the output of pbs_rst= at command
&nbs= p; &= nbsp; Example: Given below an exampl= e in which we can see the change in pbs_rstat output forma= t:
= &nb= sp; = Previous Output: If max res= ervation id is "9999999" and server name is "servername-cent7" then output displays like:
Resv ID | Queue |
---|---|
R9999999.s | R9999999 |
=
=
New Output: Now, if column width is inc=
reased to 15(Resv ID) and 13(Queue) and max reservation id also increased t=
o higher limit "999999999999" then output would be like
Resv ID | Queue |
---|---|
R999999999999.s | R999999999999 |
&nbs= p; Note: Increased= the column width of "Resv ID" (from 10 to 15)and "Queue"(from 8 to 13) only
Limitation: With this implementation the maximum length of Job name (PBS_MAXJOBNA= ME) will be limited to 230 character wide.
