    2828ALMOS-MK defines six vseg types:

    3737 1. '''CODE''' : This private vseg contains the user application code. ALMOS-MK creates one CODE vseg per active cluster. For a process P, the CODE vseg is registered in the VSL(P,Z) when the process is created in reference cluster Z. In the other clusters X, the CODE vseg is registered in VSL(P,X) when a page fault is signaled by a thread of P running in cluster X. In each active cluster X, the CODE vseg is localized, and physically mapped in cluster X.
