Abstract
A method, computer program product, and data processing system for sharing memory protection tables and address translation tables among multiple Host Channel Adapters are disclosed. The protection and address translation tables for a shared memory region are written in memory of the host. The Host Channel Adapters are registered with the memory region so that each adapter stores an address pointer to the tables. In this way, the tables need not be duplicated for each adapter.
