The IBM vectors are 128 elements in the current implementation, but the architecture definition allows for 16 (I think) to 512; it's done in a nice way so the compiler doesn't have to KNOW what it is. The Amdahl (Fujitsu) VP's have a reconfigurable register section that can go from something like 8 regs of 8192 to 256 regs of 256. If the Hitachi machine is the one being nmarketed here by NAS, it exists, and they claim some pretty impressive price/performance relative to the IBM 3090's.
