Um, what exactly are you doing with Sage? Your question seems to assume that absolutely anything you do with Sage would parallelize to use all available CPU resources, which is impossible (see, e.g., "Amdahl's law") unless we do something really stupid. That said -- people regularly ask exactly the same question you just asked. -- William > > Alex > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/groups/opt_out. -- William Stein Professor of Mathematics University of Washington http://wstein.org -- You received this message because you are subscribed to the Google Groups "sage-support" group.
