Abstract
A data processing system and method provide for sharing a partition of a memory in the system between a first task and thread and a second task and thread, so as to more efficiently enable adaptive sharing of data for local tasks or alternately copying of data into I/O buffers for remote tasks. The system and method automatically determine whether sharing has been established between two local tasks and if not, the system and method will adaptively copy data for messages to be transferred between the tasks.
