The ARM11 does not pack much punch, there is no networking (though it should not be too difficult to add) and it is not even in production yet. But it does seem fun. Plus, $1000 would get you 40 units ...<BR>

Tema: [Beowulf] 512 atoms in a box<BR>
<BR>
I was thinking about the seamicro box - 512 atoms, 64 disks and<BR>
either 64 Gb ports or 16 10G ports. it would be interesting to<BR>
look at what the most appropriate "balance" is for mips/flops<BR>
of cpu power compared to interconnect bandwidth. maybe the seamicro<BR>
box is more intended to be a giant memcached server - that is,<BR>
the question is memory bandwidth/capacity versus IC bandwidth.<BR>
<BR>
in any case, you have to ponder where the amazing value-add is -<BR>
compactness? I'm not sure it competes all that well compared to<BR>
48 core-per-U conventional servers (whether mips/flops or memory-based).<BR>
<BR>
here's an idea, more commodity-oriented (hence beowulf): suppose you<BR>
design a tiny widget that gets all its power via POE. maybe Atom or<BR>
ARM-based - you've got 15-20W, which is quite a bit these days.<BR>
for packaging, you need space for a cpu, nic and sodimm. maybe some leds.<BR>
<BR>
plug them into a commodity 1U 48-port Gb switch, then stack 10 of them<BR>
and you've got a penny-pincher's approximation of a Seamicro SM100000!<BR>
<BR>
not going to win top500, but...<BR>
