You can by why would you? for a HPC application you normally want as
much cpu horse power as you can get, putting more vm''s on a single
cpu doesn''t give you that.
Now i will admit we DO use xen in our HPC environment. We use it for
testing scheduling policy without needing a large number of real
boxes. We do not currently use xen for production clusters. (we are
beowulf style clusters) but at SC last year people were using xen
for a type of checkpoint, so they could stop execution of jobs, save
the vm to disk (xm save) run a time critical job and restore the
saved image.
I just wouldn''t do it my self.
