[gridengine users] default value in complex cannot be changed via a user request

Dear all,

I ran into some trouble with the default value of h_vmem. I set to be 
consumable=yes and also set a default value of 1G. When I submitted a 
job asking for example for 10 slots with 1G per lost the job crashed 
with an error in the queue logs saying that the h_vmem needed by the job 
(around 3G) was over the hard limit of the queue (local host instance) 
of 1G. I would have thought that the request of 1G per slot, so 10G in 
total would override this and give enough memory for the job.

Setting the default value to 6G resolved the problem, but as we might be 
dealing with larger memory jobs in future I would like to find a proper 
fix for this. I am running SGE as installed by ROCKS 6.1.1 (OGS/Grid 
Engine 2011.11) and the only thing I changed was to set h_vmem to 
consumable=yes and set the relevant h_vmem values for each host.

I want users to request memory and jobs to be killed if they exceed the 
requested amount, so h_vmem seemed to be the way to go. But how do I set 
a small default value that users can change if they need more? Or should 
I set it to forced without a default and force users to request it?

Thanks in advance
