Apparatus and method for efficient transfer of data and events between processes and between processes and drivers in a parallel, fault tolerant message based operating system
A parallel, fault-tolerant computer system in which data is transferred between processes in a single CPU by two methods. In a first method, the data is copied each time it is transferred. In a second method, the data is not copied, but is passed through a shared memory, queueing system. The first method is used to ensure fault-tolerance and linear expandability. The second method is used to minimize the time required for inter-process communication. Use of the shared memory queueing system allows for faster communication between processes executing in a same CPU.
