[Beowulf] Intro question

Malcolm,

Just a plug for the recherche' space-minimization solution (I'm still
thinking about my own hypothetical cluster, as you are). This article
http://www.linuxjournal.com/article/8177
is Ron Minnich's "Beowulf in a Lunchbox"; 16 mini motherboards with risers.

You could possibly consider a rackable system with diskless nodes
(hand-me-down desktop motherboards, with onboard NIC, would fit in 1U
slots,  right?) and put the disks and power supplies and routers in a dense
2 or 3U space. Then maybe you could just load it all into a rack lafter the
initial development in your basement. But as RGB mentions it depends on lots
of things; heat, dust in your office, the budget, etc.

Incidentally, if you built say 4 single-slot quad-core nodes with 2
dual-slot 8 core (per board) nodes, then you could find out which
bandwidth/mem-channel/per-core configuration works better for your app,
instead of anticipating; in the case that your initial prototype needn't be
ideal.

Peter

P.S. incidentally, I think that Ron Minnich is the one I knew in High
School; which is a bit odd, parallel to RGB from Duke. Next I'll meet a
bewulfer from my kindergarden class :-)
