This paper presents how to make inexpensive personal supercomputers getting the merit of commercial-off-the-shelf (COTS) continuously after the death of vector supercomputer venders. It is designed to realize this goal without any modification on CPU, bridge chips on motherboard and memory chips. Only plugging a new memory module with vector load/store function make an inexpensive home-use personal computer into a node similar to Earth simulator's one. These nodes can be connected by COTS Infiniband 4X type or 12X type switches in order to make parallel systems. COTS SO-DIMMs on the memory modules can be accessed fastly by remote nodes by using AOTF, BOTF, RDMA and remote vector load/store operations. Applications with unit striding or indexed accesses are going to be accelerated. How to accelerate NAS CG class B is shown as an example. Used evaluation methodlogy is about 500 times faster than that of SimpleScalar based methodlogy. It is predicted with bandwidth analysis that up to 8.75 times improvement can be achieved by proposed system for a single CPU Pentium4 PC without parallel processing.
