Tilera - Manycore

lorgix · 2012-02-12, 12:08

Could this be a good siever? (ECM?)

Tilera has created a 100-core processor and some other interesting stuff.

Does anyone here have experience with their products?

no I don't have experience with the products. without accounting for latency etc. the 100 core at 1.5 GHz is about 22 times my 2 core processor.

Strangely enough I was looking at their web page a couple of days ago, though for entirely different reasons.

There product may be very interesting indeed but until relatively easy access to a working system is available it's hard to make any significant comment.

I just realized my calculation is for 1 processor with 3 it's up to 66 times the 8000 series is 4 processors for up to 88 times.

The architecture is different. So IPC differs.

I believe I read somewhere that the CPU-power of the 700MHz ARM in Raspberry Pi was comparable to that of a 300MHz PIII. Another piece of interesting hardware. ($25 with 128MB RAM, or $35 with 256MB RAM + Ethernet and an extra USB 2.0)

So you can get one 700MHz ALU from Raspberry Pi for $25 and 2.5 watts, or 1792 800MHz ALUs from AMD for $500 and 250 watts, and the software hasn't been ported to either.

Tilera are packet-processing machines, as far as I can see their role is to have a lot of network interface onto the chip and to be easier to program than an FPGA of similar cost. xilman may well have a more perceptive opinion.

For those interested some documentation is available here, including the instruction set.

To sum up what is lacking: divisions and efficient floating-point. The rest looks rather complete and interesting

fivemack, why are you mentionning AMD? Are you talking about GPGPU?

My opinion is pretty much the same as yours for all but the 3000 series. I don't yet know enough about the latter to tell whether they are more suited to other applications.

Yeah, it does... complete cache heirarchy, inter-tile communication via register network, SIMD instructions... It looks like it would be fun to work with.

Indeed

can't divisions be affectively done via other things ?
