Load Sharing: Processes are not assigned to a particular processor. A global queue of threads is maintained. Each processor, when idle, selects a thread from this queue.
Gang Scheduling: A set of related threads is scheduled to run on a set of processors at the same time, on a 1-to-1 basis. Closely related threads / processes may be scheduled this way to reduce synchronization blocking, and minimize process switching. Group scheduling predated this strategy.
Dedicated processor assignment: Provides implicit scheduling defined by assignment of threads to processors. For the duration of program execution, each program is allocated a set of processors equal in number to the number of threads in the program. Processors are chosen from the available pool.
Dynamic scheduling: The number of thread in a program can be altered during the course of execution.

What is term that describes to any type of scheduling in which a running thread may involuntarily lose control of the CPU to another thread?
interrupt
What is orphan thread meaning in CPU scheduling?
When a particular thread has many dependent thread, and that particular thread is terminated, then all the threads that depends on that terminated thread will no longer belong to something and they will certainly mislead to their each functions. This is what it call orphan thread.
What are the devices which contain multiprocessor and multicomputers?
multiprocessor and multicomputer
Difference between realtime and multiprocessor scheduling?
uniprocessor : - A type of architecture that is based on a single computing unit. All operations ( additions, multiplications, etc ) are done sequentally on the unit. . multiprocessor : - A type of architecture that is based on multiple computing units. Some of the operations ( not all, mind you ) are done in parallel and the results are joined afterwards.
What has the author Nai-Fung Chen written?
Nai-Fung Chen has written: 'An analysis of scheduling algorithms in multiprocessor computing systems' -- subject(s): Computer programming, Critical path analysis, Multiprocessors
What are user level threads?
•No special support needed from the kernel (use any Unix) •Thread creation and context switch are fast (no syscall) •Defines its own thread model and scheduling policies
What are some common strategies for solving the job scheduling problem efficiently?
Several strategies are commonly used to solve the job scheduling problem efficiently, depending on the complexity of the tasks and available resources. Popular approaches include greedy algorithms, which make the best immediate scheduling decision at each step, and dynamic programming, which evaluates multiple possibilities to find an optimal solution. Heuristic and metaheuristic methods are also widely used for large or complex scheduling problems where finding the exact optimal solution may be too time-consuming. In practical business environments, task prioritization, resource allocation, workload balancing, and automated scheduling software help improve efficiency and maximize resource utilization. Modern scheduling platforms can also integrate with route planning tools such as Upper Route Planner to optimize both job assignments and travel routes, helping businesses complete more work while reducing time and operational costs.
What does multiprocessor free and multiprocessor kernel mean in re to OS Build Type?
In the context of operating system build types, "multiprocessor free" refers to an operating system build that does not support multiprocessor systems. This means it is designed to run on single-processor systems only. On the other hand, "multiprocessor kernel" refers to an operating system build that supports multiprocessor systems, allowing for parallel processing and improved performance by utilizing multiple processors simultaneously. The inclusion of a multiprocessor kernel enables the operating system to take advantage of the capabilities offered by multiprocessor hardware configurations.
Why do you need multiprocessor environment?
for improving the efficiency of the computer system.In multiprocessor environment , instructions can be executed parallely.
What is CPU scheduling?
The CPU scheduler is the part of the Operating System that determines when to allow each thread to execute. Usually this is done by seeing if all the wait conditions, such as IO wait, timer wait, semaphore wait, etc. have been cleared, and if the thread priority or round-robin turn criteria have been met.
What are example of multiprocessor system?
Multiprocessor systems have gained popularity over the years as they allow the user to do more than they could with a single processor system. Xbox 360, CELL, and Sequent are examples of multiprocessor systems.
