This assignment is based on Programming Project 6.40 in Silbershatz. Implement the ProducerXConsumer program according to the instructions for Project 6.40 for both Linux and Win32 threads. (1) However BEFORE you add any synchronization to your code use sleep()/usleep() calls to force your code to produce as many different types of synchronization bugs as possible. Use the output produced by your program and for your Linux implementation only also use 'strace -f' to explain how and where in your code the synchronization bugs occur. Be sure to use the command line argument for strace - see the man pages for details on this Each of your threads should fprint out a line of output to stderr when it is first started, and again when each buffer of input/output is processed.
Submit code and annotated test output for these experiments explaining where the race conditions occur.
NEXT, modify your code by adding appropriate synchronization (mutex locks and/or signal semaphores and/or count semaphores) so that it always executes correctly. Use diff on Linux & comp on Windows to verify that the input & output files are identical by annotating your trace output clearly and concisely and using diff/comp to compare the contents of the input & output files. Explain the logic of how you synchronized your code in your design documentation by submitting high level pseudocode with semaphore synchronization (init, p(), v()) and an explanation of the logic that you used; (2) submit wellXcommented source code and annotated output (including strace listings) to demonstrate that your code is executing correctly, despite the sleep/usleep commands from the previous part.
Run your final program with 3 buffers (each of which is 13 bytes long), 6 producers, 3 consumers and a file that contains about 200 bytes; annotate & submit this output. (3) For the third part of this assignment, modify your synchronization so that a deadlock condition occurs, and document this situation by explaining in your design documentation how deadlock was produced in your code and how it can be avoided.
Define the WindowsNT WindowsNT provides a two-level approach to resource management: process and thread. The process is the uppermost level and contains most of the application

Define spooling. A spool is a buffer that holds output for a device, like printer, that cannot accept interleaved data streams. When a request finishes printing, the spooling s
What are the multithreading models? There are three models:- a) Many-to-One model b) One-to-One model c) Many-to-Many model
Q. Under what conditions do page faults occur? Explain the actions taken by the operating system when a page fault occurs. Answer: A page fault take places when an access to
Q. Is there any way to execute truly stable storage? Describe your answer. Answer: Truly steady storage would never lose data. The fundamental technique for steady storage is
We are use to using variables within C without thinking about where they are stored. Most variables are dynamic i.e. can change, therefore they are stored in Ram, unlike a program
