List of top 4 computers in the World:
The top one doubled in speed last week.
The PowerPC 440 System-on-chip is created by AMCC, who buy PowerPC 4XX IP from IBM.
The 440 in those systems is a highly custom design by IBM. The 440 cores take up very little room on the die, it's all cache and/or interconnets. The dual FPUs (which do all the computing) aren't even inside the 440s.
What if someone create Infiniband cluster based on 10 thousands processing element boards with 970 MP / Antares System-on-chip (2.5 GHz / dual core)?
Even 10,000 of them would probably come in second to the new record from last week.
Such a system would also have positively frightening power consumption - at least a couple of million watts - IBM used the custom 440s because they needed to get the power consumption right down for the final system - whihc is projected to deliver 360 Tera FLOPs.
PowerPC clusters don't use the 2.5GHz parts for a good reason...
Anyway, I'd use Myrinet not Infiniband ;-)
