    I'm working on a C project, and I require troubleshooting assistance. The project is experiencing errors that need to be fixed. Are you familiar with such a project: Write two programs that operate in NON-BLOCKING mode and communicate Hello messages back and forth. The programs must be named Exercise11_4a.c and Exercise11_4b.c. The two programs use a single shared file for messaging and a semaphore for synchronization. Program A (Exercise11_2a) will start the exchange by sending Hello B to B (Exercise11_2b) and, once the message is received, B will print the message and then send Hello A to A. Program A will then print the message from B and respond with Hello B. This should continue until the programs are stopped. The output should look something like t...

In the case of a stream, the channel decides when to finish the stream - the user interface should be able to search for entities by name - user thread selects next videos to watch (randomly) - the channel publishes new content at random moments - the user can view detailed information about the object in a separate window - use a semaphore or monitor to solve multithreading problems - saving and reading the simulation state should be solved using serialization - the basic evaluation criteria are code quality and functionality consistent with the requirements; the aesthetic values of the visualization work to the advantage of...

Note, you need to maintain a counter that counts how many REPLY messages you receive from all other hosts. If no enough REPLY received, you still need to call recvfrom function (and therefore the process is blocked). Requirements: You can only use C programming lanuage to complete this project. Your implementation should not rely on any extra library (to compile your code). Your code must compile by using gcc installed on the Linux workstations in FH 133. Your distributed mutual exclusion primitive must be based on UDP based message passing. 3. (30 points) The UDP networking platform (code) is provided.

    The Reader Writer Problem In this project you will need to provide a solution to readers-writers problem in which several processes (readers and writers) are trying to access shared variables. Obviously, if two readers access the shared data simultaneously, no adverse effects will result, hence, they are allowed to access. However, if a writer and some other process (either a reader or a writer) access the data simultaneously, chaos may ensue. To ensure that these difficulties do not arise, we require that the writers have exclusive access to the shared data while writing to the data. The solution must guarantee that: If a writer has begun writing process, then No additional writer can perform write function No reader is allowed to read If 1 or more readers are reading, then Othe...

You need to use the Nachos synchronization primitives given to you in your implementation. Make sure you make a call to (char c) in your consume method so that the test program can test your implementation. The database has the functions startRead, endRead, startWrite, and endWrite. You are to implement the Read- ers/Writers problem using these functions. The test classes Reader and Writer are located in SynchTest.java.
