The GRAPE-4 System --- 1995 and 1996 Gordon Bell Prize Winner

GRAPE-4 is a special purpose computer for astrophysical simulations being developed in our lab. The peak speed exceeding 1 Tflops has been achieved. The figure shows four cluster units and the host computer. The host is a DEC Alpha AXP 3000/900.
