Does HiDRO take advantage of multiple virtual CPUs in a machine, or does it simply manage multiple tasks on a single virtual CPU? If the latter, I would be better off running multiple virtual machines, regardless of whether the program being run is HiDRO or DDR.
Which brings about another question, is either HiDRO or DDR significantly faster?

Alternatively can also run HiDRO stand alone on the bare processor via IPL from tape or CP PARM disk by selecting it as the "nucleus" to IPL with.
