Concurrent Computer Corp has agreed to partner Novell Inc’s Unix Systems Group in developing real-time extensions to the Unix System V.4.2MP multiprocessor operating system. This is to ensure that System V.4.2MP complies with the new IEEE Posix 1003.4 standard for real-time computing. The first offering will include queued signal capabilities to ensure prioritised delivery of asynchronous event notifications and will enable applications to include data value in a signal that identifies a particular event. The Oceanport, New Jersey minimaker will release its own implementation of System V.4.2MP, or version 7, of its Real-Time Unix operating system, by the second quarter of next year, and Unix Systems Group will follow with a standard about six months after that. Version 7 will be backwards-compatible with earlier releases, but users will need to recompile their applications.
