Pthread mutex työt
...student, she goes outside to the waiting area to see if there are waiting students. If so, she takes the next student and begins to help them. If there are no waiting students, she returns to her chair in he office and takes a nap. If a student shows up and sees the TA sleeping, they sit in her chair and wake her up. Using POSIX mutex locks and sempahores, design a solution to the sleeping TA problem. A simple solution can use one mutex lock and two semaphores: - the mutex lock for controlling access to the chairs. (This of course can be simplified by keeping track of the number of waiting students which roughly resembles the number of students sitting in chairs.) - a semaphore for signalling the sleeping TA that a student has shown up. - a semaphore for signal...

Write a multi-threaded C program to find all prime numbers up to N using Sieve Eratosthenes algorithm(where N is an integer greater than 1).To find the prime numbers up to N, the program will use Pthreads library to implement a pipelined parallelism model.

Remember that all global memory is shared among threads of a process. Both threads need to count to 2,000,000 which means a correct overall count is 4,000,000. Thread1 needs to be modified so that every time it sees (counter− > value%100) == 0 it increments counter− > value by 100. That counts for an 100 individual updates. You also need to keep track of how many times this happens and report it. Use the POSIX implementation of threads. You will need t...

A shared variable, called shared_count, keeps track of the number of items in the shared buffer. While this program does work (thanks to the mutex locks and unlocks already provided), it is unfortunately very inefficient. To see just how inefficient this program is, compile the original minor5.c program (using the pthread library) and execute the program. You should type in some keys and see them echoed back on the screen in their correct order.

...access the same resources declared as global variables. It has many potential problems because some changes by one thread affect other threads which need the previous information. This conflict may cause severe problems and must be avoided. Synchronization tools are developed to solve this problem. Semaphores are one of the tools. There are two types of semaphores – binary semaphore (similar to mutex) and counting semaphore. A thread which obtains the semaphore can access the critical resources, whereas other threads should wait until the semaphore is available to get. Using the semaphores, we can control accesses to the critical resources. For more information, review the chapter 5. III. Implementation The program has the similar format as the first project. Wh...

Need some help with PTHREADS. I want to keep over 1000 threads opened at any time, something like a thread pool. Here is the code : After spawning 300 threads it begins to give errors, return code from pthread_create() is 11, and after that keeps executing them one by one. BUDGET : 100 USD (just fix pthreads bug and make it run, no more than that).
need some1 who has good expertise in multithreading applications using pthread library.
using pthread need to implement thread pool one shud be well versed with Linux environment and can debug the multithreaded API's
thread pool implementation using pthread api's it shud not be too complex to understand
