Abstract

The growing gap in performance between processor and memory speeds has created a problem for data-intensive applications. A recent approach for solving this problem is to use processor-in-memory (PIM) technology. PIM technology integrates a processor on a DRAM memory chip, which increases bandwidth between the processor and memory. In this paper, we discuss two PIM-based multiprocessor systems, the System Level Intelligent Intensive Computing (SLIIC) Quick Look (QL) board and a hypothetical V-IRAM multiprocessor board. The former system includes eight COTS PIM chips that are connected by a flexible FPGA-based interconnect network. The V-IRAM board modeled contains four Berkeley V-IRAM PIM processors (currently under development) that are connected using FPGAs. The performance of several data intensive applications on the SLIIC QL board is measured. The performance of the applications on the V-IRAM board is modeled at the clock cycle level. The performances of these boards are compared with a PowerPC-based multicomputer and a Pentium system.
