It used to be that supercomputers used highly specialized processors, interconnects and software. It appears today that this space is getting commoditized.
How to build a supercomputer:
1. Find lots of money
2. Take a pick of a few CPU vendors -IBM blue-gene, Intel Xeon, AMD Opteron;
3. Pick a co-processor preferably a graphics processor from any company starting with n
4. Choose an interconnect - Infiniband from Mellanox or Ethernet
5. Choose the switching topology fat-tree/ mesh and then the switch vendor based on (4) above.
6. Pick a light-weight OS
7. Run linpack
8. Make some noise on energy efficiency to sound like you are environmentally concious. Then go back to your mega-watt design
9. If not in the top500, add more cpus, switches, try again!
I just cannot figure out why this has to have China (or US) name-tagged.
To me it's like paying Barcelona FC, Real Madrid, and AC Milan together to represent China in the World Cup.
In the end, it's the three clubs making a huge load of money and nothing to do with China.
The competition of building the fastest computer has helped propelling the development of faster processors, faster interconnect bus and communication link. As far as I remember, Japan is leading as of today just a couple weeks ago. China was a couple month ago. Who will earn the lead by when?
