Introduction
The main requirement shown to modern
information technologies, creation of
the technologies working in real time is. This creation of a combination of the software
and systems of technical providing which can solve various questions in parallel. Now
technical providing already outstripped the software. Despite creation of multinuclear
processors, software are still intended for consecutive work.
And it slows down
calculation process. Now with a view of acceleration of process of parallel
programming many tools and means are widely used. From them we will consider
features of an OPEN MP package.
Open MP (OpenMulti-Processing) is the interface of the applied programming
intended for creation of multiline appendices, and is developed for parallel computing
systems with the general memory. Open MP consists of
a set of compilers and the
collection of instructions for libraries of special functions. The Open MP standard is
developed, that within the next 15 years to calculate architecture with the general
memory. The Open MP standard in an expanded look for parallel computing systems
with the distributed memory in recent years is issued. At the end of 2005
the Intel
company provided software product of Cluster Open MP.
