The whole purpose of PC's is that they are generic to use. I remember
how in past decision taking bought low clocked junk for big price -
much against the wish of the sysadmins who wanted a PC for every
student exclusively. Outdated slow junk is not interesting
to students. Now you and i might
Interesting...
That seems to be a growing trend, then. So, now we just have to wait for them
to actually exist. The $35 B style board has Ethernet, and assuming one could
netboot and operate "headless", then a stack o'raspberry PIs and a cheap
Ethernet switch might be an alternate approach.

I thought the plan was for them to be powered from the HDMI connector,
but it appears I was wrong, it looks like it can use either microUSB

Latency didn't keep up with the CPU speeds...
Todays nodes have a CPU core or 12 and soon 16 which can execute,
let's take a simple integer example in my chessprogram and its IPC,
about 24 instructions per cycle

Excellent.. Purdue.. and have we really been beowulfing since 1994? I'll be
that the earliest clusters can legally buy alcohol now...
So, If I build a cluster with Arduinos using the PAPERS style interface, what
will it be called...
BeoPaperDuino?

I'm looking for the papers on the PAPERS cluster interface (based on using
parallel ports.. back in the 90s) and, of course, if you search for the word
papers, you get nothing useful..
I can't remember who the authors were or where it was done (I'm thinking
Yes..
And there's been a bunch of "value clusters" over the years
(StoneSouperComputer, for instance)..
But that's still $3k.
I could see putting together 8 nodes for a few hundred dollars. Arduino Uno R3
is about $25 each in quantity.

Completely superior chip that Cortex-M3.
Though i couldn't program much for it so far - difficult to get contract jobs
for.
Can do fast multiplication 32 x 32 bits.
You can even implement RSA very fa
Yes.. better the widget that one can whip on down to Radio Shack and buy on my
way home from work than the ghostware that may live for Christmas future.
Also, does the Raspberry PI $25 price point include a power supply? The Arduino
runs off the USB 5V power, so it's one less thing to hassle wit
That's all very expensive considering the cpu's are under $1 i'd guess.
I actually might need some of this stuff some months from now to
build some robots.

I think something like the Raspberry Pi might be easier for this sort
of task. They'll also be about $25, but they'll run something like
ARM/linux. Not out yet thought.

For educational purposes..
Has anyone done something where they implement some sort of message passing API
on a network of Arduinos. Since they cost only $20 each, and have a fairly

I don't have grey hair (part grey beard, I confess), but I have plenty of
