ABSTRACT:
A method is provided for sharing and/or transporting data within a single node of a multi-node data processing. The method avoids the necessity of making more than one copy of the data to be shared or transported. The method is tunable based on the size of the data segment involved. A shared memory area between tasks running in different address spaces on the node is used to coordinate the process and for task to task communication. The increase in efficiency provided by the intranodal process described herein also provides advantages to the internodal communication process since more CPU cycles are available for that aspect of system operation.
