MPI (Message Passing Interface) has been effectively used in the great enactment calculating community
for years and is the leading programming model. MPI implementations typically associate an MPI procedure with an
OS-process, subsequent in a coarse-grain indoctrination model where MPI processes are certain to the corporal cores.
Fine-Grain (FG-MPI) ranges the MPICH2 application of MPI and devices a combined runtime system to allow multiple
MPI processes to perform simultaneously confidential an OS-process. FG-MPI routines fibers (coroutines) to provision
numerous MPI courses confidential an operating scheme process. These are fullfledged MPI processes each with their
individual MPI rank . The main goal of this paper is to provide a better sympathetic of decomposition technique in
MPICH and analyse to improve coarse-grain mechanism in distributed environment. MPICH is a high-performance and
generally portable implementation of the Message Passing Interface (MPI) standard (MPI-1, MPI-2 and MPI-3). To use
MPICH2 for programs with frequent small message passing.So objective is to study decomposition methods, which are
used to recover MPI implementation.
