A method and structure for inter partition communication within a logical partitioned data processing system are provided. Each partition is configured for an inter partition communication area (IPCA) allocated from partition's own system memory. Each partition's IPCA combined together forms a non-contiguous block of memory which is treated as a virtual shared resource (VSR). Access to VSR is controlled by hypervisor to maintain data security and coherency of the non-shared resources of a partition. Messages are written to and read from VSR under a specific partition's IPCA for inter partition communication. No physical shared or non-shared resources are involved during inter partition communication, hence no extra overhead on those resources, thus achieving optimized performance during inter partition communication.
A method of sharing information between different partitions in a partitioned data processing system, wherein a specific block of memory is assigned to each partition and is accessible by the assigned partition, comprising the steps of:
A virtual memory structure in a partitioned data system, wherein each partition has its own memory with each memory being accessible from its own partition,
An article of manufacture comprising a computer usable medium having a computer readable program embodied in said medium, wherein the computer readable program, when executed on a computer, causes the computer to:
