VSM is implemented through a programming model, where software creates and manages all of the communication between the processors and the memory. VSM is implemented on a distributed computing environment, but provides the connected processors with the impression that they are in a shared memory environment (a single memory shared between multiple processors). It is primarily implemented to provide a uniform value of the data being processed within the memory to all connected processors.

For example, if a processor is changing/altering the variable X, all other processors working on the same variable will see the new value.
