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.
