[Beowulf] Blue Collar Computing

I gotta say I didn't find the signal-to-noise ratio all that high in the
Blue Collar Computing article cited below.  And statements like this
seem downright misleading:

'National labs that do large-scale "heroic computing" -- the Departments
of Energy and Defense (DOE and DoD) and the National Science Foundation
(NSF) -- will continue to concentrate on monumental, "grand challenge"
problems.'

Really?  But, for instance, LBNL's Chombo software
(http://seesar.lbl.gov/anag/chombo/index.html) doesn't seem targeted to
only grand challenge problems:

'Chombo provides a distributed infrastructure for parallel calculations
over block-structured, adaptively refined grids. Chombo's design is
uniquely flexible and accessible. Any collaborator will be able to
develop parallel applications to solve the partial differential
equations in which she is interested with far shorter development times
than would be possible without the infrastructure. Very careful design
and documentation allows said collaborator to enter the software at many
levels. She will be able to use Chombo to investigate deep technical
issues of adaptive mesh refinement algorithms or to simply adapt the
example applications to solve different scientific problems.'

We hope to use Chombo in a new water resources modeling we're
developing, hardly a grand challenge application, yet possible only with
the advanced work already done by a National Lab.
