with the PE allocation rule

    allocation_rule 1

a N-slot parallel job will be scheduled across N hosts. A dynamic
distribution of granted memory is not possible.


> Hello All,

> mem_free=1.5GB job.sh.
> However is there a way where  I can do this in a parallel mode where it picks

> 1.5GB+1.5GB or as per the free memory available in the machines included in 
> the queue.
> Any inputs here?
