Introduction

One of the earliest parallelization techniques was through the use of POSIX threads, usually shortened to just pthreads. Like other threading constructs, pthreads parallelization relies on the assumption of a shared memory environment and is, therefore, typically used only on a single node with the number of active threads limited by the number of available CPU cores on that node. While pthreads can be used with a variety of programming languages, in practice the main target language is C. To parallelize a Fortran program using threads, OpenMP is almost certainly a better idea while C++ programmers would probably find the constructs in the Boost threading library or which are part of the C++11 standard to be more attractive options, given their consistency with object-oriented design.
