  The parallel and distributed processing are becoming de facto industry
standard, and a large part of the current research is targeted on how to make
computing scalable and distributed, dynamically, without allocating the
resources on permanent basis. The present article focuses on the study and
performance of distributed and parallel algorithms their file systems, to
achieve scalability at local level (OpenMP platform), and at global level where
computing and file systems are distributed. Various applications,
algorithms,file systems have been used to demonstrate the areas, and their
performance studies have been presented. The systems and applications chosen
here are of open-source nature, due to their wider applicability.
