    5 The GIET_VM is a fully '''static operating system''' for shared address space, '''many-cores architectures'''. These architectures are generally  NUMA (Non Uniform memory Acces), because the memory is logically shared, but physically distributed, and the main goal of the GIET_VM is to address these NUMA issues.

    77The GIET-VM assumes that the hardware architecture is structured as a 2D mesh of ''clusters''. There is one physical memory bank, and several processor cores per cluster. Each processor is identified by a composite index [x,y,p] where x, y are the cluster coordinates, and p is the local processor index.
