Parallel environment allocation_rule=$pe_slots requires all processes to be on the same node.   See "man sge_pe".

Subject: [GE users] gridengine 6.1u3 + openmp


I read the doc carfully, and watched the mailling list, i just can't find the answer i'm looking at.

I would like to know how i can run openmp program in a cluster composed of small nodes.
I've got 17 nodes of 4 processors each.
So if a user use 4 processsors for his openmp program, how can i tell gridengine that the 4 nodes must be in the same node ?

I know i can do a parallel environment with the $fill_up allocation rules, but i don't know how to tell gridengine to launch the code only when a node is free.
