Title: Method for zero-copy message passing
Inventor: MUN KYEONG DEOK
IPC: G06F12/00
Filed: 1998-12-03
Abstract: PURPOSE: A method for zero-copy message passing is disclosed to eliminate memory duplication overhead caused by message-passing and to minimize the decline in performance by sharing a memory, which is used for passing process, demo and network card message passing, in a network environment. CONSTITUTION: A method for zero-copy message passing is composed of transmission, reception, and direction. When sending message to a remote host, message is copied from processor(201)'s local area to an area where memory(203)'s DMA is possible. A network card(204) transmits data to network, therefore eliminating overhead through zero-copy. A memory area(203) for all processes of message passing and network card receives designated area allocated by boot time. The memory area receives the physical address of start point and size that are returned by operation system and informs the general processor of the information. Each process finds the area where common memory can enter within its imaginary memory, maps the physical memory area and imaginary memory area using a map. Therefore, when writing in its imaginary memory space, it's actually writing in common memory.
