A producer/consumer problem with two processes accessing a single shared variable. A producer/consumer problem with two producer processes producing values to be stored in a shared buffer of size n with a single consumer process con- suming the values. A pipe-like mechanism between two processes where the pipe is a buffer of 4096 bytes.
