How do threads communicate in multithreaded programs?

Threads in multithreaded programs communicate by exchanging data through shared resources. Pthreads provides condition variables, semaphores, and mutexes for this purpose, whereas the Win32 threading API provides events, semaphores, mutexes and a specialized form of mutex variable called a critical section.

What is the difference between OpenMP and thread libraries?

OpenMP-compliant compilers are available for most operating systems, including Windows and Linux. Thread libraries, on the other hand, are not portable. Obviously, the Win32 API is only available on Microsoft operating systems. Even then there are slight differences in supported features between different versions of Windows.

How to optimize thread behavior in multithreaded programs?

Tailoring thread behavior to a particular runtime environment is often overlooked in multithreaded programs. On a single-user system, for example, allowing idle threads to spin may be more efficient than putting them to sleep. On shared systems, however, forcing idle threads to yield the CPU may be more efficient.

Is the system heap safe to use by multiple threads?

Background The system heap (as used by malloc) is a shared resource. To make it safe to use by multiple threads it is necessary to add synchronization to gate access to the shared heap. Synchronization, in this case lock acquisition, requires two interactions (i.e., locking and unlocking, with the operating system – an expensive overhead.
