Shared Memory Coordination

Shared Memory Coordination. We will be looking at process coordination using shared memory and busy waiting . So we don't send messages but read and write shared variables. When we need to wait, we loop and don't context switch. This can be wasteful of resources if we must wait a long time.

The Critical-Section( ??? ) Problem

The Critical-Section( ??? ) Problem. n processes all competing to use some shared data. Each process has a code segment, called critical section , in which the shared data is accessed.
