A Symmetrical Communication Interface for Distributed-Memory Computers

example, both sends and receives can operate on both Applications have very diverse communication local and remote buffers. Although this communication requirements. Although individual algorithms often use model does not correspond directly to the low-level regular communication patterns, there is little regularity communication primitives supported by the hardware, it across applications or even across different phases of the can be implemented efficiently, and it gives the users same application. For this reason, a low-level more control over how and when transfers over the communication interface should support the unrestricted, network takes place. The interface is the lowest-level reliable exchange of variable-length messages. communication interface for the Nectar multicomputer.
