Management method, adapter, and program for coherency lowest point (LPC) memory using service layer adapter

摘要

A low coherency point (LPC) memory is managed using a service layer adapter. An adapter is coupled to a processor and an accelerator on a host computing system, wherein the processor is configured for symmetric multiprocessing, the management receiving, by the adapter, a memory access instruction from the accelerator. Reading the real address for the memory access instruction by the adapter, and determining, using the base address register on the adapter, that the real address is intended for the LPC memory; Determining, by the base address register, a memory access request between an LPC memory location on a host computing system and another memory location; Address, and transmitting the media controller for LPC memory, media controller for the LPC memory includes the steps of that, the transmission is attached to the adapter through a memory interface, a.
