Part I I– In this part of the project, you need to develop a global synchronization mechanism called barriers. When the threads call the barrier, they will not be able to proceed until all threads reach the barrier. You need to write your own barrier function using semaphores. Use this function between the levels described above to implement the sorting algorithm. Do not use the barrier function available in Pthreads. ...

    The goal of this project is to become familiar with semaphores in the Unix operating system. In addition, you will implement a concept, provide it as a statically linked library, and use it to solve the following problem. Problem: Write a program to compute the summation of n integers in each of the following ways and assess their performance. Assume that n is a power of 2. 1. Partition the n integers into n/2 pairs. Use n/2 processes to add together each pair of integers resulting into n/2 integers. Repeat the method on the n/2 integers and continue until the final result is obtained. (This is a binary tree algorithm.) 2. Divide the n integers into n/log n groups of log n numbers each. Use n/log n processes, each adding the numbers in one group sequentially. Then add the n/log n re...

    ...for the volunteers using semaphores as synchronization primitives. Now, all jokes aside, this is an actual problem related to computer science. The agent represents an operating system that allocates resources, while the volunteers represent applications that need resources. The problem is to make sure that if resources are available that would allow one or more applications to proceed, those applications should be awakened. Conversely, we want to avoid waking an application if it cannot proceed. A restriction of the problem is that you are not allowed to modify the agent code. (Indeed, if the agent represents an operating system it makes sense to assume that you don’t want to modify it every time a new application comes along.) The agent uses these binary semaphores...

A green light, often called a “high green” because it was displayed at the highest place on a signal staff, indicated that a train was cleared to operate at full speed. The term “High Green” suggested that all operations were proceeding as planned. “High Green” traces John Shanahan’s return to the only job he ever wa...
