Openmp is an implementation of multithreading, a method of parallelizing whereby a master thread a series of instructions executed consecutively forks a specified number of slave threads and the system divides a task among them. It supports widely used programming models for parallel and distributed computing and provides a rich set of optimizations for serial programming models. See this page if you are upgrading from a prior major release series of open mpi. It is not meant to be the official or complete implementation due to the fast changing nature of the specification and our resource limitations.
