Cool, but what is the cost? The website doesn't even have a word about how to
obtain thier product. Insane, IMO.
http://www.google.com/products?q=tilera returns ONE (useless) hit.
Or is this chip not yet released?

Look at Tilera http://www.tilera.com/products/TILEPro64.php 64 cores on a
chip in the same technology as Intel used to get two cores on a chip. But
local memory is small, so it's no good for general computing. Someone might
try it for computer go though.

I think we will get another 64x to 256 x density then it will stop, for
single chips. We should eventually get desktop machines with thousands
of
cores, but probably never with millions of cores. There really are
limits
built into physics L
How about the cores becoming much smaller and simpler?
Intel's CPUs are approaching a billion transistors on a chip. But you
can probably make a very decent and fast CPU with just a million
transistors. Maybe double that number to give each a bit of cache
memory. If you can see computers with thousands of cores, does that
already assume they'll be simpler? Or could we have a few (hundred)
heavy-duty CPUs like today's for multi-purpose use and a card with a
million simpler CPUs on them next to it for tasks suitable for
parallel processing? A hybrid system if you will.
Just thinking out loud, I'm obviously a layman when it comes to
semiconductors.
