Not directly relevant to the discussion, but I attended recently a
talk from the main developer of STXXL (http://stxxl.sourceforge.net/),
an STL-compatible library for handling huge volumes of data. The keys
to efficient processing are support for parallel disks, explicit
overlapping between I/O and computation, and I/O pipelining. More
details are available at
