Concurrent Programming Project 1( Due Sept. 23th)
You have to write a concurrent program using the BACI system. BACI provides the
mechanisms to support the concurrent execution of programs written in the C - -
programming language. This tiny programming language, C - -, allows you to use a
constructs to initiate the concurrent execution of two or more processes. All you have to
do is to enclose all the process (threads) to be executed concurrently in a cobegin { … }
construct. For instance, we might indicate the concurrent execution of processes P1, P2,
and P3 by using:
Cobegin{P1 (…); P2 (…); P3 (…)}
Process synchronization can be carried out in C - - using Semaphores and Monitors.
Write a concurrent program using semaphores to implement the Producer/Consumer
algorithm. We will have two cases:
1.- One producer, one consumer, and one buffer.(the producer run faster than the
consumer)
2.- One producer, one consumer, and one buffer.(the consumer run faster than the
producer)
You must turn in a floppy or CD with the pseudo code of the above mentioned
procedures and clearly indicate the initial values, and a running version of your solution
in BACI with results for different data sets(different buffer sizes). The buffer size must
be smaller than the number of items produced.
