The Mosix architecture

The Mosix architecture was developed by prof. Ammon Barak team on Hebrew University of Jerusalem, and it gives to Linux clusters the better of clustering. The features of Mosix are:

• Automatic load balancing of process. Mosix asures the best use of all the resources of the cluster;
• Memory ushering. Process will run wherever they have space, for not to swap;
• Descentralized control There is not a central authority;
• Common interprocess space. A Mosix cluster looks like an alone machine to the user;
• Backwards compatibility. It can be used PVM, MPI and sockets; all the clustered and Beowulf applications runs on a Mosix without modifying code;
• Fork and forget programming model. Creating a Mosix parallel aplication is so easy as calling the fork() Unix POSIX function;
• Transparent to the user; and, finnaly, the applications can give clues of where is their bottlenecks, for Mosix optimize them; but this is not compulsatory.
