There is some really interesting stuff in this article.
It has been argued on this list in the past (and successfully, I
think), that memory bandwidth is at least as serious an issue as
MFLOPS.
---------------- quote from article ---------------
"While today's machines are amazingly fast number
crunchers, many data-intensive applications are
slowed because of the time it takes to simply access
information from the memory chips. The Blue Gene/L
design will run these applications much faster
because the machine will be populated with data-chip
cells optimized for data access. Each chip includes
two processors: one for computing and one for
communicating, and its own on-board memory. Each of
the data-chip cells will work on a small part of a
larger problem. This increase in data access speed
will make a huge difference in the kinds of results
these machines can produce and the kinds of problems
they can solve."
