Admission

To avoid unnecessary resource consumption, the admission manager executes a three-way handshake protocol for transferring SMs between neighbor nodes. First, only the resource table is sent to the destination for admission control. If the SM admission fails, the task will be informed, and it can decide on subsequent actions. If the SM is accepted, the admission manager checks, using the code bricks' IDs (computed off-line by applying a hash function on the code), whether the code bricks belonging to this SM are cached locally. Then, it informs the source to transfer only the missing code bricks. (These code bricks will also be cached upon arrival.)
