Systems and methods to support scalable bitmap-based P_Key tables in high-performance computing environments

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for supporting a P_Key table based on a scalable bitmap in a high-performance computing environment. The method provides at least one subnet comprising one or more switches, a plurality of host channel adapters and a plurality of end nodes. Multiple end nodes can be associated with at least one of multiple partitions, each of which is associated with a P_Key value. The method can associate each of one or more switches with a bitmap-based P_Key table out of a plurality of bitmap-based P_Key tables. The method can also associate each of the host channel adapters with a bitmap-based P_Key table out of a plurality of bitmap-based P_Key tables. [Selection diagram] FIG. 13
