Currently, when requesting multiple slots for a job, it's necessary to configure and use a parallel environment:

$ qsub -l slots=2 ./
Unable to run job: "job" denied: use parallel environments instead of requesting slots explicitly.

I have some SGE users who would like the ability to request multiple slots without being required to use a parallel

   ------- Additional comments from reuti Thu Oct 1 04:49:41 -0700 2009 -------
Simple question: why?

Not requesting a PE would let SGE in the dark whether they all should be located on one and the same machine, or multiple machines. And if
you got multiple machines: how to tell the jobscript where to find them, when there is no pe_hostfile created?

If it's just for SMP jobs, you can use the default setting of a new PE without any start/stop_proc_args. Whether someone request:

-l slots=5


-pe smp 5

is not much of a difference and would indicate clearly to SGE that it's a parallel job and how to handle additional resource requests.
