I wouldn't say that this is disjunct - you can also use a queuing system in a good way on such a machine IMO. But the idea was more: you have an application which is only Open MP parallel but scales in a nice way. Hence you could run larger jobs on such a machine. Is it worth to try it (and regarding this setup I was asking, whether anyone is using it and has experience - it's like running OpenMP across nodes).
