- * A vseg is '''public''' when it can be accessed by any thread T of the process, whatever the cluster running the thread T.  It is '''private''' when it can only be accessed by the threads running in the cluster containing the physical memory bank where this vseg is mapped. A '''private''' vseg is entirely mapped in one single cluster K. For a '''public''' vseg ALMOS-MK implement a global mapping : In all clusters, a given virtual address is mapped to the same physical address. For a '''private''' vseg, ALMOS-MK implements a local mapping : the same virtual address can be mapped to different physical addresses, in different clusters.

  * A '''public''' vseg can be '''localized''' (all vseg pages are mapped in the same cluster), or '''distributed''' (different pages are mapped on different clusters, using the virtual page number (VPN) least significant bits as distribution key). A '''private''' vseg is always '''localized'''.
