[Beowulf] Configuration management tools/strategy

[Peter St. John]

Walid,
I just wanted to mention genetic algorithms; control engineers use them
e.g. in chemical plants to dynamically optimize variable inputs (pressure
in a pipe, temperature, ingredient mixes...) for measurable outputs
(valuable gunk at the end), the point being that the inter-relations among
all the inputs, at the level of precision possible to the machinery, is too
esoteric for an exact qualitative model.

I think that managing diverse simultaneous applications (that each flourish
in their own mix of bandwidth, cache, numbers of threads on cores &c) where
a mix of hardware is available in a heterogeneous cluster, might be a
similar challenge.

So if someone were interested in trying a GA for dynamic performance
optimization of long-running applications   with mixed available hardware
I'd be glad to hear of it and I'd want to help.
