Multi-threaded concurrency programming with threads, Computer Engineering

Assignment Help:

Your task is to implement a memory manager that manages page reads and writes from multiple client threads. In the first programming task the memory manager keeps all the pages in a memory buffer large enough to fit all the pages and the server processes a list of requests and sends them to clients to log. In the second programming task a user is allowed to specify a memory buffer size limit. The memory manager needs to place some of the pages on disk in order to cope with the buffer size limit. To do this the memory manager uses the least recently used (LRU) page replacement algorithm in order to choose which page to evict from memory when the memory is full. In the third task you extend the solution for task 1 so that requests are sent from the client to the server instead of all the requests originating in the server.

Please look at the AssignmentDiagram.ppt file in the assignment folder to gain a better understanding of the assignment requirements. Sample input and output files are also provided in the SampleFilesForTasks1to3.zip file.

Please do not use sleep anywhere inside your code. Or something that simulates a sleep system call. Eg. while (1) { }. However you are allowed to use the pause(), pthread_cond_wait() or pthread_cond_timedwait() system calls and their Java equivalents to block a thread or process.

Please submit separate source files for each of the three tasks.
