Well... I have an engineer here who want to run a 2048 core job. When
he tries, he gets this error:
I mean, a real use-case that needs the limit to be part of the queue
config, and one that can't just use the method I described in:
http://gridengine.org/pipermail/users/2012-May/003705.html
If you have a real good reason that setting S_DESCRIPTORS &
H_DESCRIPTORS in sge_conf(5) is not enough, then we can try to improve
things a bit... but the bottom line is that we need a good use-case.
(Even if we had unlimited time, we still don't want to add code that
duplicates existing code. Having said that, we can remove existing
code and switch to the new code if needed.)
You should be able to fix the issue by setting S_DESCRIPTORS &
H_DESCRIPTORS, or you can check the environment that starts the execd,
and see if it has a lower descriptor limit...

I have already modified the queue config as follows:
execd_params S_DESCRIPTORS=20480 H_DESCRIPTORS=65536 \
ENABLE_BINDING=true
With this in place, it seems odd that from one of my queues I
get a default setting for the number of descriptors of 1024.
So I have two questions really:
1. Why am I getting different behavior from the two queues?
2. Since H_DESCRIPTORS=65536, why can't I request that amount and get it?
