YoLinux Tutorial: POSIX thread (pthread) libraries
The POSIX thread libraries are a standards based thread API for C/C++. It allows one to spawn a new concurrent process flow. It is most effective on
multi-processor or multi-core systems where the process flow can be scheduled to run on another processor thus gaining speed through parallel or
distributed processing. Threads require less overhead than “forking” or spawning a new process because the system does not initialize a new system virtual
memory space and environment for the process. While most effective on a multiprocessor system, gains are also found on uniprocessor systems which
exploit latency in I/O and other system functions which may halt process execution. (One thread may execute while another is waiting for I/O or some other
system latency.) Parallel programming technologies such as MPI and PVM are used in a distributed computing environment while threads are limited to a
single computer system. All threads within a process share the same address space. A thread is spawned by defining a function and it’s arguments…
