This book demonstrates the practical implementation of distributed systems by using the recent open source compilers and environments. Faculties and students can use this book as laboratory manual for distributed operating system.

Distributed systems are workstations that can communicate with each other and data processors, as well as different hierarchical architectural configurations of data processors that have differing data storage capabilities.
A distributed system can be much larger and more powerful given the combined capabilities of the distributed components, than combinations of stand-alone systems. But it's not easy -for a distributed system to communicate in reliable way. This is a difficult goal to achieve because of the complexity of the interactions between simultaneously running components.

Message Passing Interface (MPI) is a standardized and portable message-passing system developed for distributed and parallel computing. MPI gives user the flexibility of calling set of routines from C, C++, Fortran, C#, Java or Python....
