[LINK] ANU Auctions Supercomputer (fwd)

[David Singleton]

Peter Strazdins suggested the assembler is quite similar to SPARC
except for the bits like

     vadd  vr32 vr64 vr120

which do 2048 double precision flops in one instruction.  The vector
pipes are 16 wide so 16 results each cycle.  One of the most amazing
bits is the memory bandwidth - measured 17.6GB/s per cpu and this
dates from when PCs were lucky to see 100MB/s.  This is achieved with
512-way memory interleaving!  (Still way behind the NEC shared memory
vector-parallel systems with 32K-way interleaving.)

Also the OS had a pfork() - the vpp is distributed memory but it can
fork to a different processor/OS to spawn parallel jobs - neat.
