Sounds like a Multiflow Trace.  4 simultaneous 64-bit FP reads
from memory over 4 data busses to 4 modules, each containing 2
FPUs (separate add and multiply), 2 IUs, 64 sp/32 dp FP
registers, 64 32-bit integer registers, instruction cache only. 
Memory consisted of up to 8 memory controllers with up to 8 banks
of memory per controller, with a 7 beat latency in returning
data.
