Abstract
A method is provided for operating a communications adapter employed in a multinode data processing system in a fashion which enhances the performance of remote direct memory access data transfers. The system is provided with pointers and a table which are employed to determine whether or not an address which has been supplied for the transfer has already been mapped to a real address at the source or destination node. The table is also preferably provided with counters which can be incremented or decremented to enable the use of least recently used mechanisms at the upper level protocol layers to more efficiently control the setting and resetting of table entries.
