Hi,

To optimize the utilization of our pool of Abaqus licenses, I want to implement 
some form of preemptive scheduling, where urgent jobs can force suspension of 
less urgent ones.
I have used Marc Olesen's qlicserver (run as a load sensor) to account for 
external uses of licenses, which works fine.
I have created a Abaqus-dedicated queue with suspend, resume and terminate 
methods for suspending, etc...
The abaqus jobs that run on execution hosts are suspended all right, and the 
licenses are released correctly as far as the FlexLM license server is 
concerned, but for SGE they are *not* released, and consequently, no new jobs 
that need them are executed.
Since qlicserver compares the license use reported by the FlexLM server with 
that of SGE to determine the external (non-SGE) uses, and adjusts (reduces) the 
SGE complex accordingly, it seems possible to do something similar for 
suspended jobs: they are reported by qstat but not by FlexLM. Their license use 
count could be used to increase the SGE complex as long as they are suspended.
As far as I know, this would require an extension of the qlicserver. Or am I 
missing existing possibilities?
Are any of you aware of similar efforts in that direction ? Or alternative 
solutions ?

Thank you, best regards,

Patrick L. Goes
