I was trying with h_vmem and my findings are: Memory consumed is multiplied by the number of slots user request in case h_vmem is set to "Yes". It is not multiplied if set to "Job". However, job memory limit (as per "ulimit") is in both cases multiplied by the number of slots consumed which is bit confusing.
So if we set up H-vmem to "JOB" and 2Gb, then "qrsh -pe ade 4", then we obtain a shell with 16Gb virtual memory limit but only 2Gb is subtracted from the host memory. Is that behavior expected?
