Abstract
A method, system and apparatus for multicasting or broadcasting a piece of data from one partition of a partitioned computer system to a plurality of partitions of the system are provided. When a partition needs to transfer data to more than one partition of the system, the partition first stores the data into a global memory accessible by all partitions of the system. The memory is then marked “read-only” to ensure that the data is not over-written and the Ids (identifications) of the recipient partitions are passed to a piece of firmware or hardware of the computer system. This firmware or hardware then alerts the recipient partitions that there is a piece of data ready to be read in the memory. Once all the recipient partitions have read the data, the global memory is reverted to a “read” and “write” memory.
