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: http://www.osl.iu.edu/~dgregor/bgl-python/ Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
