why are you requesting two instances for the memory?

- PE attached to a queue - does a job w/o mem_free/token run?
- Number of slots in the PE definition reflects the number of cores in the cluster?

I also tried different variations of the qsub (removing -hard or part of the arguments, setting mem_token=50M ... ), but it doesn't work.
