#1476 duplicate Add a per-host consumables and resource maps like in Univa Grid Engine michel

Univa Grid Engine has implemented a very interesting system, allowing a "per host consumable" :

This allows for example a pe job to request N Slots and 1 complex within the same job.

In OGS, asking for a pe of N slots with a consumable complex leads to asking N time the complex and give the following message in the scheduling info: cannot run in PE "default" because it only offers 0 slots

#1475 fixed Client JSV slow down submit too much Dave Love <…> wangvisual

Without client JSVs, qsub can be finished within 0.03 seconds, with one JSV, qsub need 1.1 seconds, with 2 JSVs, qsub need 2.2 seconds. The JSV script only takes 0.1 second to run so it's issue with GRD.

Actually we'e using Univa Grid Engine 8.1.4 but as the code are from the same base, SoGE might have the same issue, you can verify it by just compare the turn around time for: date +%X.%N ; echo ls | qsub -P bnormal -clear; date +%X.%N and date +%X.%N ; echo ls | qsub -P bnormal -clear -jsv jsv_script ; date +%X.%N

We've reported to UGE and they will give a fixed version, but I just noticed they didn't open source their core since 8.0 any more.

The related codes are jsv_stop() in & sge_peclose() in

jsv_stop will first send 'QUIT' to jsv process and then call sge_peclose, at this time, the jsv process is about to exit, but most of the time it not becomes zombie yet, so first call of waitpid(pid, NOHANG) will fail and sge_peclose will sleep for 1 second and retry.

The 'sleep 1' is the root cause of the slowness.

BTW, There's one workaround for this issue, If the JSV script suicide after sending the ACCEPT or REJECT command, then the TAT is very short, eg: jsv_accept('Job is now accepted'); kill "INT", $$;

#1469 fixed New functionality for sge_ca (CSP certification management tool) markdixon

Hi Dave,

I am almost certain you'll hate this one :)

There are some patches (against 8.1.3) attached, to "improve" the sge_ca tool for managing CSP certificates; the aim is to allow overlap of multiple valid certificates.

Note that they change the behaviour of some existing options (-renew, -renew_sys, -renew_sdm).

What do you think?

I'm not running them in production yet so, even if you like them, you might want to wait a bit before putting them in a release.
