There was some discussion of this recently. The most direct approach to the problem is to annotate some or all of numpy's inner C loops with OpenMP constructs, then provide some python functions to control the degree of parallelism OpenMP uses. This would transparently provide parallelism for many numpy operations, including sum(), numpy's version of IDL's total(). All that is needed is for someone to implement it. Nobody has stepped forward yet.
