    But how is that any different than having a PC on your desk?

    I see the deskside supercomputer as a revisiting of the
    “workstation” class computer. Used to be that PCs and Apples were
    what sat on most peoples desks, but some had Apollo or Sun or Perq
    workstations, because they had applications that needed the
    computational horsepower (or, more likely, the high res hardware
    graphics support.. A CGA was pretty painful for doing PC board
    layout).

    Same sort of thing for having the old Tektronix 4014 graphics
    terminal, rather than hiking down to the computer center to pick
    up your flatbed plotter output.

Jim,

One big difference is that this machine will be sold to department chairs and Deans not as a desktop or high end workstation but as a cheap "Supercomputer" that needs no support. The PC support available in an organization may be completely unable to deal with the realities of HPC. That's when I get an urgent call about a machine that I don't know about. The clock started ticking the day that the machine arrived and that's the impossible timetable to which I will be held. In other words, even with my absolute full attention my efforts will be presented as failing to set up the machine in a timely manner. In addition all of the other researchers who have invested in the centralized resources will complain that they are not getting the attention that they need.

I think that there are times that machines such as this on a departmental or even researcher level make sense even in an organization that provides central resources. But those times are the exceptions. I have 2.5 System Admins. I have ~300 machines in two different locations as standalone servers and parts of clusters. We can get by with this level of staffing through standardization of hardware and operating systems (currently 90% linux, 9% Solaris, 1% IRIX), security standards that lock down unused ports and services, and careful testing of software (physical sciences, math, OR, bioinformatics) before it is made generally available. With budget cuts looming on the horizon, adding support for new department level systems without additional staffing would leave us unable to continue to provide adequate support for the central systems. IMHO. YMMV.
