Presentation:

The Mome DSM provides a shared segment space to parallel programs running on distributed memory computers or clusters. Individual processes can freely request mappings between their local address space and Mome segments. The next release of Mome (Mome  1.0) will integrate more dynamicity (adding and removing nodes), better scalability (using a hierarchical implementation), more consistency models (sequential consistency, release consistency, application-managed consistency, parallel reduction), support for background checkpoint consolidation, and better support for the POSIX SMP computation model.

Current status:

Mome is implemented in C (50,000 lines). It involved 24 persons-months. The current stable release is Mome  0.8. The next major release Mome  1 will integrate all current developments.
