You do not tell us what problem you are facing. numpy/scipy are pretty
efficient at multiplying sparse matrices. It is always possible to run
out of memory at the sizes you are talking about, but that should be
obvious. Beyond that, your best hope is a map-reduce algorithm with
something like Hadoop.
