Migshm

Migshm is a software patch that enhances openMosix by providing Distributed Shared Memory (DSM) capabilities. The main feature of this project is process migration for applications that utilize shared memory, such as apache and Xfracky.
One of the major drawbacks of openMosix is the lack of migration support for multi-threaded applications and those that rely on shared memory. Consequently, these applications cannot take advantage of openMosix's load-balancing features. With Migshm, this limitation is addressed.
The acronym Migshm stands for Migration of shared memory. Although not a complete DSM at present, it is adequate in enabling shared memory applications to benefit from openMosix. Migshm facilitates the migration of SYSV shared memory-based processes through system calls such as shmget(), shmat(), shmdt(), and shmctl(). Moreover, threads created using the clone() system call can also be migrated with Migshm.
In summary, Migshm is a promising tool that opens up new possibilities for openMosix users by overcoming limitations associated with shared memory and multi-threaded applications.
