Abstract
A communication arrangement facilitates transfer of messages among a plurality of processes in with a computer, the computer having a memory shared by the processes. The communication arrangement comprises, allocated to each process, a plurality of buffers, and a plurality of postboxes each associated with one of the other processes. Each process includes a message size determination module and a message transfer module. The message size determination module is configured to determine whether a message to be transferred to another process can be accommodated by a postbox. The message transfer module is configured to (i) in response to a positive determination by the message size determination module, store the message in the postbox associated with the process as allocated to the other process, and (iii) in response to a negative determination by the message size determination module, store the message in one of the buffers allocated thereto, and providing a pointer to the one of the buffers in the postbox associated with the process as allocated to the other process.
