Just to make sure I understand what you are doing, is you want to set job #
bounds to, (for simplicity sake ) serverA 1-100, serverB 101-200 and serverC
My guess is you don't want job # collisions for metric gathering or
something similar, please correct me if I am wrong. We have a metric utility
that would break if we tried to suck in a second job for a particular server
that has already used that job # set as a key in our database, and I too, am
currently looking for a fix/work around. ( same server jobid overlap )
Wouldn't you at some point just end up with reusing ID's on the same server?

The highest avail job # is defined in include/server_limits.h and handles
rollover ( starting at 0 again )
#define PBS_SEQNUMTOP 99999999 /* top number for job sequence number, reset
/* to zero when reached, see req_quejob.c
Thanks for any input as to why you are using this,
