Abstract: We present a fast shared memory multiprocessor with uniform memory access time. A first prototype (SB-PRAM) is running with 4 processors, a 128 processor version is under construction. A second implementation (HPP) using latest VLSI technology and optical links shall run at a speed of 96 MHz. To achieve this speed, we first investigate the re-design of ASICs and network links. We then balance processor speed and memory bandwidth by investigating the relation between local computation and global memory access in several benchmark applications. On numerical codes such as linpack, 2 and 8 GFlop/s shall be possible with 128 and 512 processors, respectively, thus approaching processor performance of Intel Paragon XPS. As non-numerical codes we consider circuit simulation and raytracing. We achieve speedups over a one processor SGI challenge of 35 and 81 for 128 processors and 140 and 325 for 512 processors.
