[torqueusers] Re: timesharing cpus

[Davide Cesari]

I am in a similar situation where I need to allow unlimited jobs to run 
on a cluster frontend node and I solved by using the :ts time sharing 
definition for the node and by defining a special queue including only 
that node, so that qsub -q that_special_queue sends the job there and 
the :ts definition allows an indefinite number of jobs to be running 
simultaneously. Without defining a special queue I found no way, in 
torque, to convince a job to run on a time sharing node, any other 
positive experience with :ts?
	hope this helps, Davide
