Processor (FT-matrix 2000+): 128 cores, 2TFlops in DP --> Node: 3 processors, 6TF -->
The prototype system: 512 nodes, 3PFlops. The interconnection is 200Gbps. Details will be available online later this month.
Looking at the Matrix processor it is very interesting: <a href="https://en.wikichip.org/wiki/nudt/matrix-2000">https://en.wikichip.org/wiki/nudt/matrix-2000</a>
Each Matrix consist for four 'super nodes' with 32 cores and its own paths to DDR4 memory. So you would imagine there are 4 separate chips in
the package, but I may be wrong. Each core has two 256bit wide vector units. Clocked at 1.2Ghz which makes sense.
A couple of observations:
A single 128 CPU machine with 256 wide vector units would have been a pretty respectable supercomputer in itself not so long ago.
If I have not miscalculated, it would have got you near the top of the Top 500 in 2010
I wish I could get a hold of one, or a test drive - probably not much hope of that.
Stu Midgley - I think you need to get your order in for a boat load of these!
So I will stick my neck out - Doug, get on a flight to Shanghai for your next clustermonkey building blocks.
