    17 For each process P, the process descriptor is replicated in all clusters containing at least one thread of P (these clusters are called active clusters). In each active cluster K, the virtual memory manager VMM(P,K) is stored in the local process descriptor, and contains two main structures:

In each active cluster K, the virtual memory manager VMM(P,K) is stored in the local process descriptor, and contains two main structures:
    1818 * the VSL(P,K) is the list of all vsegs registered for process P in cluster K,
    1919 * the GPT(P,K) is the generic page table, defining the actual physical mapping of those vsegs.
