IBM has a plan to take the #1 spot once the BlueGene project is complete
next year; their architecture is PowerPC based (each of its processor
chips has two PowerPC processors on the chip).  Their 1/128th scale
prototype is already #73.  See

http://www.research.ibm.com/bluegene/

The completed machine will have 2**16 compute nodes and 1024 I/O nodes.
The I/O nodes run a Linux kernel; the compute nodes run a tiny OS that
supports only one process but provides a Posix interface.
