[Beowulf] Odd SuperMicro power off issues

I agree with Alan, this sort of sounds like power. Proving it might
be difficult, but some ideas
* Use a different PS on a unit you can make fail
* Reduce the power demand somehow: unplug memories, disks, whatever is
unpluggable that you don't need
The ugliest idea I have is that fluent might have a pattern of power
demand that is
resonant with something in the power system, so it causes cyclical
voltage or current demand
that trips the power supply. Proving that could be really hard.
These are multicore processors
so does it depend on how many of them are running fluent and how many
are doing something else?
