Popis:	The DIVA (Data IntensiVe Architecture) system incorporates Processing-In-Memory (PIM) chips as smart-memory coprocessors to a host microprocessor. It exploits the inherently high on-chip memory bandwidth and additionally provides a separate memory-to-memory high-bandwidth interconnect across the system. By design, the DIVA system architecture targets a broad rabge of applications, including those with irregular data access patterns. At the same time, DIVA supports familiar programming paradigms from parallel computing and offers an evolutionary migration path for application development. The DIVA project is constructing a demonstration system using a conventional superscalar host processor with a main memory composed of VLSI PIM chips in place of standard DRAMs. This system has a novel mix of operating-system challenges, combining aspects of conventional "dumb" memory management and both shared-and distributed-memory multiprocessor operations. This paper describes our solutions to the memory-management problems posed by this multifaceted environment.
