Abstract:
A method for sharing memory between a first cell and a second cell of a distributed shared memory system, wherein the first cell and the second cell are separated by a fault-isolating fire-wall, comprising the steps of:(1) receiving a request in the first cell to access a page of memory that is located in the first cell, the request having been sent by the second cell;(2) determining in the first cell whether the second cell is permitted to access the page of memory;(3)(a) opening a portion of the fault-isolating fire-wall between the first cell and the second cell to permit the second cell to access the page of memory, if the second cell is permitted to access the page of memory;(3)(b) generating a record of the page of memory exported from the first cell to the second cell; and(4) closing the opened portion of the fault-isolating fire-wall.
