Is this what you mean? If not, you will have to explain your question better.

Get a faster machine. Or use fewer nodes. Or be patient and wait. Solving a graph problem with 1000 nodes is a fairly big problem for a desktop PC. It will take time. Calculations don't just happen instantly, the more work you have to do the longer they take. The last alternative is to ask on a specialist numpy list. But I expect they will probably tell you the same thing. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
