You have megalomania. There will never be a computer with 77.000 cores
in shared memory. NUMA won't scale to that extend, M(O)ESI won't scale
to that extent and the software also won't scale to that extent. sgi
has dropped is massively parallel shared memory system with its NUMA-
link-architecture because of that.
