And how do you support my operational requirements with this policy

By not over-generalizing from a general policy to a place where it
doesn't apply? Craig has worked in weather forecasting, you know.
Actually, the tone sounded like it was already over-generalized. I
merely followed the trend.
You don't run your ensemble elements as separate jobs? Isn't that
asking for disaster if something goes wrong?
Actually, it depends on what you call a "job". Apparently IBM's
LoadLeveler (hardly a Beowulf implementation, but what I'm working with
right now) thinks that the job-file defines the job. I can check-point,
sleep or do quite a bit more within the normal job script but IBM wants
to treat that as a "job". Most of my runs on that machine complete in a
couple of clock hours for a single ensemble member, or less. The job,
however, can take 8-12 hours with WRF, Holland winds, ADCIRC, WaveWatch,
SWAN and ELCIRC in ensemble mode.
Some of my WRF climate runs can go for days, however. Those are cycle hogs.
