The IEEE SCI standard defines a shared memory interconnect from the physical layer to the transport layer. However, no standard software layer is defined. One might argue that in a distributed shared memory environment little software is required because once a distributed shared memory (DSM) system is set up, all accesses can be performed by directly reading/writing from/to the appropriate target addresses. This is the main advantage of the distributed shared memory architecture. It results in the lowest possible message passing latency and transaction overhead. No procedures or system services need to be called in order to exchange data between different nodes in the system.
