OpenSSI 1.1.0 is a development release, and is not necessarily suitable for production use. It has versions for Fedora Core 2 and Debian. New features include several CFS performance enhancements and the integration of LVS-NAT. POSIX process groups and multi-threaded applications can now atomically migrate as a group. Also, processes can migrate while holding file record locks. New commands include 'fast' and 'fastnode'. Several files have been added to /proc/cluster for dynamic modification of nodedown detection parameters. Finally, a variety of bugs have been fixed.
