We switched from LSF 7 to LSF 10 in the past couple of years.
As near as I can glean/remember from that time we did this to pack jobs:
1. Created an application in lsb.applications like this:
Begin Application
NAME = packthis
BIND_JOB = PACK
End Application
2. Then in lsb.queues you would need your:
RES_REQ = order[-slots]
3. Then you need to tell all of your jobs to use the aforementioned
application, "packthis". We were already using esub to short-circuit our
bsubs and we added the application therein (we were using esub for other
stuff - we just tacked this on).
I THINK that you could have a default application for all of your jobs in
lsb.params (DEFAULT_APPLICATION) and set that to "packthis".
This last part you will have to work out.
That is what I remember and what I can glean from our old files and manpages.
