I basically agree. What I took home from Heidelberg in a nutshell is
Supercomping-Architecture really comes down to economical approaches
nowadays - making economies of scale accessible, to put it more precise,
this implying to widen the focus of designs beyond just deploying technology
for scientific use. From this point of view, the golden standard question in
the Hot Chair sessions "What commercial use for your concept do you see?" is
the crucial point of distinction. Red-Storm architecture looks charming for
its use of very balanced CPUs in terms of FP/integer capabilities in
comparison with other approaches at first glance. However, it's beyond my
scope to overlook how the combination of Linux and Catamount Os' works out
for running commercial stuff on it and how the mesh will deal with such
application, so I would appreciate any comments in this respect.
