RTEMS requires that an MPCI layer be provided when a multiple node application is developed. This MPCI layer must provide an efficient and reliable communications mechanism between the multiple nodes. Tasks on different nodes communicate and synchronize with one another via the MPCI. Each MPCI layer must be tailored to support the architecture of the target platform.

For more information on the MPCI, refer to the Multiprocessing Manager chapter.
