That is the Operating systems KERNAL's job.
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.

Threads are the actual path of execution of a program.
A process is a collection of threads that share the same virtual memory. A process has at least one thread of execution, and a thread always run in a process context. Thread is used to allocate and distribute the CPU work scheduling, many programs a re assigned to different threads and they are most of the time independent of each other. Eg: We can open many instance of MS word and MS Excel in our PC, all are monitored and managed by threads. Process is nothing but a program in execution, many threads can run under a process or many thread can combined under the one thread.

A process is a program in execution,it needs resources like CPU time,memory,files and i\o devices to accomplish its task. Threads are lightweight process
cells and genetics
Execution context within a process is called Thread. Threads run, process does not. Every process starts with one thread.
Since the core 2 duo processor has two execution units, it can execute two threads simultaneously. (If you said quad instead of duo, the answer would be four.)
A multithreaded program is one that has multiple threads in execution. They may execute parallel to one another or totally without relation to one another. In Java you can create multithreaded programs using Java threads.
A Java Thread is a thread of execution in a Java Program. A Java Virtual Machine can have a single application running multiple threads, which is known as concurrency. Threads are what make the program run. Each thread has a different priority, and when the machine queue fills up, the threads are executed in the order of their priority.
A program is an executable. A process is an executable that has been loaded into working memory and is currently executing the program. A thread is a thread of execution within a process. Every process has at least one thread, but threads can spawn additional threads as required to allow concurrent operations to be performed near-simultaneously.
