Justin and Alasdair,
Thanks for your help.
I'm sorry that you had to reformat the code. I had it written up in a
text file and was just copying and pasting it into the terminal
running sage. I suppose that the formatting must have gotten screwed
up when I copied from the text file to post here.

Without running the code, you may have a memory problem; it could be
that all previously computed results are stored until the program is
finished. You may possibly get around this by either deleting
variables after they've been used, or running the program with a
smaller range for c.

That would indeed be helpful.
BTW, tachyon is supposed to run over MPI. Can I use SAGE to run
tachyon over a cluster?

I think it is RealField(sci_not=True) or something like that.

Hi,
I really liked the method for speeding numerical integration of ODES
presented in the sage documentation. However, it uses the GSL solver
instead of the scipy.integrate.odeint I normally use.
I tried to apply the same methodology but I can't get past this error:
