Abstract: System and method for supporting configurable legacy P_Key table abstraction using a bitmap based hardware implementation in a high performance computing environment. A mapping table in DRAM can be provided through the use of a software based SMA that implements the mapping table. With this mapping table, it is possible to provide a legacy compliant view of a bit map based P_Key table. Such a legacy compliant view can be called a virtual P_Key table, or a configurable legacy P_Key table abstraction.
