Maybe you are talking about the edges of a graph with 1e9 nodes. This
structure is surely quite sparse, so you don't need to store the edges
in a matrix, you can manage is as a sparse structure, and maybe you
don't need a Blue Gene.

If you find ways to clean your data, reduce the vertex and arc count,
and if you have a lot of memory, then maybe Boost Graph for Python may
suffice:
