Just to add to what Ondrej said - there are two different settings in the
initial cgroup integration implemented.
One allows to over-commit memory as long as there is no memory pressure in the
kernel. But the actual
behavior depends on the Linux kernel. For debugging what Grid Engine set you
No direct support for that in SGE.

mean it is executed. Hence you would not have not any guarantee that
both are running at the same point in time.
You could submit the successor before the other one and give it the job id

Hi Mikhail
That is indeed strange and the support request is handled properly in the
support portal. Things I can imagine: You are using host resources which
are requesting cores implicitly when requested (having cores attached with
topology masks) or you are running into an rare strtok() issue
Hi Bill,
You changed the global configuration (qconf -mconf or qconf -mconf global).
This is most likely overridden by the host local configuration.
Try with changing it in the host local configuration (qconf -mconf ).
You are right it takes a few seconds that the changes are propagated but

Hi Joe,
Univa Grid Engine 8.3 added such a functionality to its APIs (WebService API)
so that you can submit on behalf of another user. The intention is to
simplify building web portals. But this is restricted to users listed in the
new sudoers Grid Engine ACL.
We can chat privately about that
There is unfortunately no way in SGE to limit main memory.
h_rss / s_rss does not work with the rlimit call in Linux kernel version above
2.4.
Hence in Univa Grid Engine we introduced multiple ways for doing main memory
limitations. If you have cgroups support turned on then the cgroup takes
Hi,
Please notice the difference between set linear:1:0,0“ and
set linear:1“. The first one means - give me one core starting
at socket 0 core 0 (which means here obviously you are
requesting core 0 on socket 0). The second means that
you want one core on the host and the execution daemon
takes
Since queue requests are not a part of DRMAA1 you
should use DRMAA_NATIVE_SPECIFICATION, which allows
you to set (almost) any qsub command line parameter
available. You can also use job categories but than
you have to configure it in the qtasks file.
DRMAA version 2 specifies queueName in the job

The easiest way would be to give a job a name with qsub -N job1 (or use -terse
for getting the job id) and
then using -hold_jid for the second job. More details you will find in the qsub
man page. Of course you
can also use DRMAA, or more unusual an array job with task throttling (-tc 1).
You can set arbitrary signals to be sent when suspension
is triggered (like SIGKILL). See: man queue_conf

What you could do is creating a queue for each GPU you
have on a host and assign them a queue exclusive GPU complex.
The amount of GPU queues are limiting then the amount of
GPU jobs. Then the total amount of cpu cores must be limited
differently by a RQS on a per host basis.
